Re: [Matplotlib-users] Hovemuller Diagram

[Sudheer Joseph]

Thank Daswson  & Sterling,
   Got it, you meant the data should not have date and 
longitude against each grid point instead should have only 2 vectors rather 
than grid.
with best regards,
Sudheer

Hi,

Is there a way to make the below as a hovemuler diagram which I tired but could 
not succeed  

import pandas as pd
 
dates = pd.date_range('20130101',periods=30)
df=pd.DataFrame(np.random.randn(30,5),index=dates)

Re: [Matplotlib-users] Graphing in an existing PyGTK window

[Sudheer Joseph]

Hi Paul,
    If you start python like below with qt console. You will get plots 
with out controls etc. You can right click on plots and save it as png. Else 
from command prompt as pdf as you wish.


ipython qtconsole  --colors=linux  --pylab=inline

[Matplotlib-users] modification to m.scatter

[Sudheer Joseph]

Dear Developers/users,
 I updated matplot lib to 1.4.2 and below example appears to be 
not working for m.scatter. May I know what change is implimented ?. m.scatter 
plots the river discharge in gridded format if the x,y=meshgrid(lon,lat) is 
used else it do not plot over map.

Thank you,
  Ifact I was referring to the example given on the page.

Becasue it has reference to the data to be downloaed, I thought it is better to 
send the link rather than sending the code which need data.

Re: [Matplotlib-users] modification to m.scatter

[Sudheer Joseph]

Sorry,
 in below steps, the converting lat lon to map projection coordiate is 
not working unless I do meshgrid. If I do meshgrid then the scatter 3rd axis 
get plotted at each grid which is not expected 

the figure after In [16]: do not result if we follow the steps

m = Basemap(projection='robin',lon_0=0,resolution='c')
x, y = m(df_data['lonm'][0:50], df_data['latm'][0:50])

 There are
 lots of code examples on that page. You have yet to provide
 a sscce. Nor have you posted what happens when you run your
 sscce. At the very leat, post the traceback or the bad image
 that differs from what you expect.

[Matplotlib-users] Corr plot in subplot

[Sudheer Joseph]

Dear Matplotlib exprets,
I am trying to place the corrplot in subplot environment. But not able to 
figure out how to do it properly. Can any one advice please?


from biokit.viz import corrplot
df = pd.DataFrame(dict(( (k, np.random.random(10)+ord(k)-65) for k in letters)))
df = df.corr()
c = corrplot.Corrplot(df)

I wanted to make the corrplot in below 4 boxes which can come out as a single 
figure. The above data is a test data actually I wanted use seasonal data for 
this purpose.

fig = plt.figure()
fig.subplots_adjust(left=0.2, wspace=0.6)
ax1 = fig.add_subplot(221)
ax2 = fig.add_subplot(222)
ax3 = fig.add_subplot(223)
ax4 = fig.add_subplot(224)

[Sudheer Joseph]

Thank you Paul,
  I could not follow fully what you meant by that in 
reply. but below is the info available with corrplot.
Kindly provide some help.
With best regards,
Sudheer
 Here are some examples provided that the data is created 
and pass to c::
 |  
 |  c = corrplot.Corrplor(dataframe)
 |  c.plot(cmap=('Orange', 'white', 'green'))
 |  c.plot(method='circle')
 |  c.plot(colorbar=False, shrink=.8, upper='circle'  )

 All the
 pandas plots that I've used take an axes keyword so
 try:
 
 c =
 corrplot.Corrplot(df, ax=ax1)
 
 or
 c =
 corrplot.Corrplot(df, axes=ax1)
 
 Do either of those
 work?

 All the
 pandas plots that I've used take an axes keyword so
 try:
 
 c =
 corrplot.Corrplot(df, ax=ax1)
 
 or
 c =
 corrplot.Corrplot(df, axes=ax1)
 
 Do either of those

Re: [Matplotlib-users] Corr plot in subplot

[Sudheer Joseph]

Hi Paul,
I could not succeed in plotting corrplot.Corrplot(df,ax=ax1).

infact the plotting procedure is
c=corrplot.Corrplot(df,ax=ax1)
then issue command
c.plot().
So there are 2 steps involved, which may be the complication. I am not very 
well versed with Matplotlib.
Kindly help.

Re: [Matplotlib-users] subplot layout

[Sudheer Joseph]

Thank you Paul,
Thanks for the tips related to margins and also about 
colormaps. Is there a way to stop the automatic aspect ratio setting ( though 
it it distors map in present case ) if I wanted to use that for other plots?

With best regards,
Sudheer

 Your
 basemap plot is likely setting the aspect of the axes to
 "equal", so it resizes the plot accordingly.
 Otherwise you'd have a pretty nasty amount of vertical
 distortion.
 When you save
 the figure, using bbox_inches='tight' will trim the
 excess white space from the
 margins:fig.savefig('map_and_bars.png',
 dpi=600, bbox_inches='tight')
 Also, you should try the new viridis
 color map :)

Re: [Matplotlib-users] subplot layout

[Sudheer Joseph]

Hi Paul,

I tried to get the new colormap suggestion from you but could not get the 
colormap package. Where can I get it? google search did not took me to the 
package/
Is it a development package?
 May I know how to use  viridis color map  with an example plot? 


Below is an example code from the link you send

'''
For each colormap, plot the lightness parameter L* from CIELAB colorspace
along the y axis vs index through the colormap. Colormaps are examined in
categories as in the original matplotlib gallery of colormaps.
'''

from colormaps import cmaps
import numpy as np
import matplotlib.pyplot as plt
from matplotlib import cm
import matplotlib as mpl
from colorspacious import cspace_converter

Re: [Matplotlib-users] Matplotlib Figure margin transparancy

[Sudheer Joseph]

Dear Expert,
Recently after up-gradation of matplotlib and ubuntu 16.04 I am 
getting transparent figure axis when using the "linux color scheme"  option in 
ipython qtconsole. May I know if there is a way to fix this issue?. I  wanted 
to keep black screen as it reduces eye strain.

ipython qtconsole --matplotlib inline

If I save the image i am able to get axis properly but to see on screen as the  
axis is not plotted with white background the black axis line and labels are 
not visible. Earlier I used to get figures as attached in second figure.

[Matplotlib-users] plot control

[Sudheer Joseph]

Dear Experts.I have been trying to modify plot properties of taylor diagram 
from below package. I wanted to make markerfacecolor as None( this allows me to 
show symbols which falls over another) of s as possible in normal matplotlib 
plots but I am not sure how to pass the argument in modified figure environment 
of taylor plot. If I try to use markerfacecolor option the code says it do not 
know about such option. I was also checking it is possible specify alpha= n so 
that the color intensity of symbol can be modified. But both options are not 
working or I am not putting it in proper way in such situation. 
Please advice if it is possible.Sudheer

This would seem like a bug in that package's code. The traceback shows that it 
is performing its own check on the passed in kwargs, and failing to recognize 
it as a valid argument. I suggest contacting the maintainers of the 
"skill_metrics" package and find out from them if there is a bug in their 
package. I am unfamiliar with this package, so I can't say anything for certain.

Cheers!

[Matplotlib-users] cross correlation

correlation between 2 time series for my research and was looking at options 
available with python and found 
http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.xcorr . However I 
wanted to save the results in a netcdf file for further use. ie the 
correlation, lags and significance if possible. Is there a way to get the corr 
and lags from the axis.xcorr ?? any help in this matter will be greatly 
appreciated.

Sudheer,

A call to axes.xcorr returns the lags, correlation (from np.correlate) and the 
line artists on the figure.

In IPython, doing "plt.xcorr??" should provide sufficient information. It's a 
pretty simple method.

Re: [Matplotlib-users] cross correlation

[Sudheer Joseph]

Thank you  very much Smith and Paul,
                                          I was away from office due to a 
medical situation. So could not respond and thank you regarding the help. I 
have got the results now and the tips from both of you were extremely useful. I 
am facing an issue with the code when I call plt.xcorr,  in a loop. it builds 
up usage of memory by python and reaches to the RAM what ever available ( in my 
4 GB laptop it reaches almost full and in my 24 GB desktop it reaches the 
available. I suspected the plot not being closed during each iteration so have 
given a plt.close('all') in the loop. after which it is taking a good time to 
run the code which was otherwise faster until ram usage reaches its maximum.
Is there a way to get out of this situation?. I am attaching the code here and 
also the link to the data I am using. If possible kindly help.

Sudheer,

For the documentation you are looking for

print ax1.xcorr.__doc__

(Paul tried to give you the IPython method of getting that documentation which 
is by typing a ? (or ??) after the desired object.)

In the documentation (at the link you gave 
http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.xcorr), it says 
that there are three objects returned by xcorr:
Return value is a tuple (*lags*, *c*, *line*) where:

  - *lags* are a length ``2*maxlags+1`` lag vector

  - *c* is the ``2*maxlags+1`` auto correlation vector

  - *line* is a :class:`~matplotlib.lines.Line2D` instance
     returned by :func:`~matplotlib.pyplot.plot`.

So the error you were getting is due to the fact that you have only specified 
two variables to hold the three returned objects.

Try:
lags,c,line = ax1.xcorr   .

(Note that you have xcorr and lags backwards in your attempt.)

-Sterling

Thank you Pierre,
                              I will test the other options. I did not know the 
number limitation in case of plt.xcorr.
Thanks a lot

Thanks for sharing the code. By a quick look at gen_xcorr_wnd.py,
you are generating a quite high number (about len(lons)*len(lats))
of xcorr series over 365 lags. Here are two thoughts about why I
would not recommend using xcorr from matplotlib for this job :

1) There is an overhead in creating a plot object which is
unnecessary since you're only interested in correlation values

2) internally, plt.xcorr uses numpy.correlate

(https://github.com/matplotlib/matplotlib/blob/master/lib/matplotlib/axes.py#L4319
 and https://github.com/numpy/numpy/blob/master/numpy/core/numeric.py#L731) 
which is quite fast but unfortunately cannot be well tuned in terms of the 
output length (only three modes : 'valid', 'same' or 'full'. Matplotlib uses 
'full' )
All this to say that when you're interested in 365 correlation
values, the internal computations takes place on (N+M-1) points
(where N, M are the length of the input vectors, i.e. 2189 if I'm
right) and so about 90 % of the output is thrown away.



This being said, there is a tiny issue : I don't know a good module
which has the (x)correlation function. statsmodel has acf (aka
correlation) but I don't remember if there is crosscorrelation. For
acf has two computation modes : one based on fft, one based on
numpy.correlate which suffer from the same problem as matplotlib's
xcorr ( 
https://github.com/statsmodels/statsmodels/blob/master/statsmodels/tsa/stattools.py#L347)

best,
Pierre

Re: [Matplotlib-users] cross correlation

[Sudheer Joseph]

Dear Pierre,
                        I was checking the plt.xcorr and it calls the 
np.correlate in side it. It calls np.correlate(ts1,ts2, mode=2).
Is there a way to see which vector is sided back in time? ie 
ts1[t1,t2,t3,t4] ts2[t1,t2,t3,t4...]  ( ts2[t2] correlated with ts1[t1] or 
ts2[t1] is correlated with ts2[t2] ie {to make out which one is the cause and 
which is effect)
in case of cross correlation it can be obtained by either sliding ts1 back in 
time or ts2 back in time. Is there a way to know this? I am not able to make 
much from np.correlate. Also is there a way to get 95% significance or p value 
from the xcorr.? in case of matlab? in matlab xcorr can be called with option 
of corcoeff instead of default cross correlation but is there similar option 
for matplotlib?
sincerely.
Sudheer

Just as a side note, mode=2 is the old fashioned way to specify
mode='full' [1]. This may help in reading the numpy.correlate doc.

This being said, I'm really unfamiliar with cross-correlations. I just
kind of know the usual 95% confidence interval for autocorrelation at
1.96/sqrt(n). Just as a quick check, this is what R uses by default, but
there are options like ci.type get more appropriate intervals for an MA
series

[Matplotlib-users] depth longitude plot

[Sudheer Joseph]

Dear Users,
                             I am trying to make  vertical section plot along 
equator of Indian ocean from 45E to 100E and latitude 0.
from levitus climatology using below code. What is the best and simple way to 
achieve this? np.meshgrid allows only 2 variables so I am not able to make  
x,y,z= using np.meshgrid(lat,depth,temp)
how to go about this? Is there a set of codes for handling such graphs?

url='http://www.marine.csiro.au/dods/nph-dods/dods-data/climatology-netcdf/levitus_monthly_temp_98.nc'
import cdms2
from matplotlib import pyplot as plt
from netCDF4 import Dataset as ncd
f=cdms2.open(url)
f.variables()
x=f.getAxis('lon')
y=f.getAxis('lat')
z=f.getAxis('z')
depth=z.getData()
lat=y.getData()
lon=x.getData()
temp=f('TEMP')
lonmin=np.where(lon==45)
lonmax=np.where(lon==100)
nlon=lon[lonmin:lonmax]
lat0=np.where(lat==0.5)
ntemp=temp[:,lat0,lonmin:lonmax]

basically I wanted to make a plot plt.plot(nlon,depth,ntemp)
Please help.

with best regards,
Sudheer

Perhaps something like:


from matplotlib import pyplot as plt
from netCDF4 import Dataset
import numpy as np


url='http://www.marine.csiro.au/dods/nph-dods/dods-data/climatology-netcdf/levitus_monthly_temp_98.nc'
ds = Dataset(url)


temp = ds.variables['TEMP']
lats = ds.variables['lat']
lons = ds.variables['lon']
depths = ds.variables['z']


# filter all but one latitude
lat_index = np.where(lats[:] == 0.5)[0][0]
lats = lats[lat_index]

# filter a range of longitudes
lon_lower_index = np.where(lons[:] == 44.5)[0][0]
lon_upper_index = np.where(lons[:] == 100.5)[0][0]
lons = lons[lon_lower_index:lon_upper_index]

temp = temp[0, :, lat_index, lon_lower_index:lon_upper_index]


plt.pcolormesh(lons, depths[:], temp)
plt.gca().invert_yaxis()

plt.show()




The indexing approach used here is quite flakey, so I certainly wouldn't use 
this in anything operational.

Hope this helps,

Phil

You can overlay contours on the pcolormesh image by simply using the 
plt.contour() function after the pcolormesh() call.  It allows you to control 
which levels to contour and you can specify the attributes of those contours 
like the color or thickness.  Note that unlike Matlab, you don't have to call 
"hold on" between plots.  By default, matplotlib will hold.

I hope that helps!

Re: [Matplotlib-users] depth longitude plot

[Sudheer Joseph]

Thanks to all Matplotlib experts for extending help,
 With the suggestions I could make the script work and I am close to the target 
I had in mind, 
Below script produces as depth longitude contou-filled plot.
However I have below concerns,
1) There is a wide gap between label and the contours ie  it appears like 
--     2.4      . is there a way to reduce this gap?
2) The labels are appearing cluttered at about 100m depth though they culd have 
spread apart at each level. Is there a way to control their placing to avoid 
cluttering?
3) Is there a way to make the longitude as in case of maps ie can the x axis 
labels be 50E 60E ... 90E
I am not sure if I am too much ambitious with regard to matplotlib, but I was 
using ferret where it takes care of the labeling.
with best regards,
Sudheer

Try inline=False for the clabel call, but that might over-do it.
 
I tried this but it totally removes the space, the inline_space=n do not appear 
to take the given value and it works always with default value..


2) The labels are appearing cluttered at about 100m depth though they culd have 
spread apart at each level. Is there a way to control their placing to avoid 
cluttering?

This has been a long-standing issue with matplotlib.  There has been 
improvements, but it still isn't perfect.  I am not familiar with some of the 
newer tricks that are available.
Hope some one tried those will respond!
 
3) Is there a way to make the longitude as in case of maps ie can the x axis 
labels be 50E 60E ... 90E

You can set the tick formatter.  Here is one example of how to do it.

[Matplotlib-users] matplotlib multiple windows comparison

[Sudheer Joseph]

Dear experts,
Is there a way to get back to the prompt after a plot is made and displayed 
with out closing the plot?
The objective is to compare to plots or check some aspect about the plot made 
from the loaded variables. This is the standard behavior of matlab after 
plotting we get the prompt and we can make another plot if we want to compare 
2. I know there is subplot option but it will be of small size if I need to 
make a spatial map at to time intervals and compare. The detail of my 
matplotlib is below


I use Ubuntu 12.04 64 bit version
and

In [3]: matplotlib.get_backend()
Out[3]: 'WXAgg'

In [4]: matplotlib.__version__
Out[4]: '1.2.0'

with best regards,
Sudheer

Thank you Phil, 
                            But I had tried it earlier after seeing a another 
mail thread. I get command prompt but no figure pops up.

In [3]: import matplotlib.pyplot as plt

In [4]: plt.ion()

In [5]: plt.plot(range(10))
Out[5]: []

In [6]: 

 Any way out??
with best regards,

Hi Sudheer,

Try the interactive mode 
(http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.ion):


>>> import matplotlib.pyplot as plt
>>> plt.ion()
>>> plt.plot(range(10))
[]

**a figure pops up here and hands you back the python command line**

Thank You Phil,
                                  It did it correctly. TkAgg is good with 
interactive plotting.

I hadn't spotted you were using the WxAgg backend too - this looks like the 
same bug that Brendan reported yesterday. 

The easiest solution would be to use another back-end until this is fixed. Do 
you have 'TkAgg' available? I currently do not have a wx installation to hand 
to try out any workarounds at the moment.

Re: [Matplotlib-users] windrose

[Sudheer Joseph]

Thank you Paul,
                          I think the font issue is the mischief of Yahoo. I 
think I should send mail in text mode rather than html then the issue will not 
be there I hope. The signature is in normal text mode I saved. Please revert 
back if my mail shows font issues again so that I can try some thing different. 
However when I see it in Yahoo there is no issues though..
with best regards,
Sudheer

[Matplotlib-users] windrose

[Sudheer Joseph]

Dear users,
          Below is a sample script I got from windrose pack. I would like to 
place 2 windroses side by side so that a comparison can be made. For example I 
have created additional variables ws1 wd1, and I would like that to be placed 
in the same row as a 1 row 2 column way. Any help in this regard will be great. 
(I tried subplot(221) subplot(222) but it do not work as the windrose uses new 
axis each time.)

from windrose import WindroseAxes
from matplotlib import pyplot as plt
import matplotlib.cm as cm
from numpy.random import random
from numpy import arange

#Create wind speed and direction variables
ws = random(500)*6
wd = random(500)*360
ws1 = random(500)*6
wd1 = random(500)*360
def new_axes():
    fig = plt.figure(figsize=(8, 8), dpi=80, facecolor='w', edgecolor='w')
    rect = [0.1, 0.1, 0.8, 0.8]
    ax = WindroseAxes(fig, rect, axisbg='w')
    fig.add_axes(ax)
    return ax

def set_legend(ax):
    l = ax.legend(axespad=-0.10)
    plt.setp(l.get_texts(), fontsize=8)

#windrose like a stacked histogram with normed (displayed in percent) results
ax = new_axes()
ax.bar(wd, ws, normed=True, opening=0.8, edgecolor='white')
set_legend(ax)

#Another stacked histogram representation, not normed, with bins limits
##print ax._info
plt.show()

Thank you Scott,

Some how I am not getting the trick of the 
rect = [0.1, 0.1, 0.8, 0.8]

I tried 
rect1= [0.1,0.1,.4,.4]
and rect2=[.4,.4,.8,.8] 
but did not work

[Matplotlib-users] legend and text

[Sudheer Joseph]

Dear users, 
            I was trying to figure out 2 things for my below script. 
1) How do I put a correct legend in below plot for both the bar and line?
Also if I wanted add another set of bars(for comparison) side by side with a 
different color is ut possible with proper legend?

2) Is there a way to keep the position of text ( eg. 
ax.text(np.mean(x),20,"N-SAMPLES: "+str(npts))) in below plot independent of 
data based location-  but dependent on plot size ie npoints from left of the 
plot and mpoints from bottom of the plot? this way it is possible to keep it at 
same place even though I use data with different range. 
Please help

Thank you Eric and CM,
I have the below piece of code and added the new definition for minorLocs, but 
gets the below error. I believe I did not fully understand the concept you 
mentioned. 

minorLocs = mdates.MonthLocator(bymonth=[1,3,5,7,9,11],bymonthday=15)
minorFmt = mdates.DateFormatter('%b')

class MonthLetter(minorFmt):
    def __init__(self):
    DateFormatter.__init__(self, "%b")
    def __call__(*args):
    s = DateFormatter.__call__(*args)
    return s[:1]
minorFmt = MonthLetter()




    531 def viewlim_to_dt(self):
--> 532 vmin, vmax = self.axis.get_view_interval()
    533 return num2date(vmin, self.tz), num2date(vmax, self.tz)

Thank you CM,
  I tried to rotate the labels but only major ticks get rotated 
and when I try with minor ticks as below I get error

p.xticks(minlabels,rotation=90)



--> 192 base =  float(dt.toordinal())
    193 if hasattr(dt, 'hour'):
    194 base += (dt.hour/HOURS_PER_DAY + dt.minute/MINUTES_PER_DAY +

Re: [Matplotlib-users] time axis format

[Sudheer Joseph]

Got a solution as below

p.setp(ax.xaxis.get_minorticklabels(), rotation=90 )
but still to understand how to get single letter from month name!

with best regards,
Sudheer

[Matplotlib-users] savefig

[Sudheer Joseph]

Dear experts,
I start ipython in ipython qtconsole --pylab=inline mode and make a plot. But 
if I use savefig('fig.png') the figure do not get saved instead I get a blank 
page.

 I also tried img.save('fig.png',png) but no use. Is there a way out or I need 
to do this after quitting and restarting in normal mode each time I want to 
save?

ipython qtconsole --pylab=inline
 

In [93]: ts.plot()
Out[93]:

[Matplotlib-users] ipython with pylab inline and normal

[Sudheer Joseph]

 Dear experts,

 I have been making some scripts to do some routine 
plotting 
 of model results with ipython qtconsole --colors=linux --pylab=inline mode for 
 fine tuning and then used the same script for running from command line  
ipython 
 alt_hyc_trak.py, the results in plot gets messed up 
 It appears the setting I did by using below commands are different for inline 
 mode and ipython.
 
 plt.subplots_adjust(hspace = -.15,wspace=.1)  
 
 
Is there a way to set the properties of plot acceptable for both.
I am attaching both figures here.
https://www.dropbox.com/s/heeadhkf9u2czns/ipython_cmdline.png

Thank you Signell,
   I was looking for better looking labels as well as a 
solution with in matplotlib without needing to install additional packages. I 
had some trouble with some libraries while trying to install iris. I was 
wondering if it is possible with in matplotlib with out additional 
installations using the features of basemap package.

Thank you Phil,
   Which repository I need to add to source list which 
allow me to install iris with apt-get install python-iris. I do not have it in 
my default lists.
