[Matplotlib-users] AXES properties
BTW: I tried to use set_position to change the position of the axes label as suggested by previous posting. No effect. - Original Message Hello, I am creating a plot with multiple y-axis (up to 6) and twinx works pretty well. The problem is that there are too much wasted spaces used up by the axes. Since I have multiple axes, it cuts into the amount of space available for the plot area. I need to know how I can squeeze some spaces out of the standard axes. First thing I discovered was that I can rotate the tick labels to vertical by: plt.setp(ax.major_ticklabels, rotation=vertical) where ax is my y-axis. But then: (1) How to reduce the space between the tick and the axes label? First I tried to place the label on top but couldn't get that to work. Then I tried to change the position property of the axis label object and that have no effect. So, can somebody please tell me how I can do these 2 things? (2) How to avoid overlapping tick labels? With the way the standard x and y axis are drawn, after I do a vertical rotate of the y tick labels, the first y tick label overlaps with the last x tick label since they are both center aligned. Is there any way to change the alignment of only the first and last tick labels of an axes (while keeping the rest center aligned)?

[Matplotlib-users] how to add text below the legend
Hi, I would like to add some text relative to the legend, let's say below it, and I don't know how to get the legend coordinates so I can pass them to the text() method. Does anyone know how to do it? Alternatively, if there was a way to add text inside the legend itself, it would also do the trick. Thank you in advance.

[Matplotlib-users] Problem formatting a 'step' histogram with a log scale and empty bins.
Hi! I want to create a histogram with the step scale and I am finding an inconstancy when using a log scale. I have a very simple example without a log scale which works just as expected creating alternating bins with value one and value zero. from pylab import * hist([0.5,2.5,4.5],bins=[0,1,2,3,4,5,6],histtype='step',log=False) ylim(0.1,1.1) show() When I change the keyword log=False to log=True, the line connecting the bins with value one to the bins with value zero disappear. Is there any way I can get them to reaper? Is this a bug that should be fixed or is there a workaround?

It works for me using svn, and the problem sounds familiar, so I think this is a bug that was fixed.

[Matplotlib-users] Values returned by axis() do not match the actual axis in the plot window
Hello, I have matplotlib widget set up in a PyQt 4 program. The axis is set for auto scaling. I'm using the following command to determine the upper y boundary: self.plotWidget.canvas.ax.axis()[3] where plotWidget is the name of the widget in my program. I get a number from this command just fine, but it doesn't always agree with the actual axis on the plot window. For instance, after plotting a curve with a maximum y-value of 0.125, the command above gives me an upper y-limit of 0.14. However, the plot window goes up to y=0.16. Sometimes things work out correctly, but they call above and the plot window do not typically agree. I really need the plot window to match what comes from this call to axis(). Can anyone offer any suggestions on what might be going wrong? Thanks, Steve -- View this message in context: http://old.nabble.com/Values-returned-by-axis%28%29-do-not-match-the-actual-axis-in-the-plot-window-tp27397234p27397234.html Sent from the matplotlib - users mailing list archive at Nabble.com. -- The Planet: dedicated and managed hosting, cloud storage, colocation Stay online with enterprise data centers and the best network in the business Choose flexible plans and management services without long-term contracts Personal 24x7 support from experience hosting pros just a phone call away. http://p.sf.net/sfu/theplanet-com ___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
[Matplotlib-users] using subscripts and tex in labels
hi all,
two quick questions about labels. first, is there a way to make
subscripts/superscripts *without* using TeX in labels? For example, I
use helvetica in all my labels and I want to plot something like:
plt.xlabel(log10) where 10 is a subscript of log, but without
doing: plt.xlabel(r$\log_{10}$), since that will use LaTeX fonts
instead of my helvetica font.
second question, when using TeX, I tried the following TeX command in labels:
plt.annotate(r\frac{\sigma}{\sqrt{\mu}}, ) but it complains that
not all arguments converted during string formatting -- but it seems
like correct TeX to me. if I try r\frac{1}{2} then it works, but
using \sigma and \sqrt inside breaks it.. any idea how to fix this?
thanks.

Unicode strings might be the answer for this. Though needs someone's
confirmation.

Have you forgotten $ ? The following works correctly in my system.
plt.xlabel(r$\frac{\sigma}{\sqrt{\mu}}$)
thanks.

See the mathtext options in matplotlibrc.template. It looks like what
you need is
matplotlib.rc('mathtext', fontset='stixsans')
maybe with the additional kwarg, default='regular', if you don't want
italics.
All this is with text.usetex=False (the default).

This is working for me with usetex=False or True but including dollar
signs to signal the use of mathtext (or TeX) parsing.

[Matplotlib-users] How to calculate relative positions between objects
Hi everyone
I've been going around matplotlib objects trying to find a way to
pre-calculate positions depending on input.
I'm trying to create a function that draws two barplots facing opposite
directions.
This is what I managed so far:
###
import numpy as np
import matplotlib.pyplot as plt
from scipy.stats import gamma
from mpl_toolkits.axes_grid import make_axes_locatable
fig = plt.figure(1, (10, 10))
ax1 = fig.add_subplot(1, 1, 1)
ax1.set_xlim(1,0)
labels = ('0-9', '10-19', '20-29', '30-39', '40-49',
'50-59', '60-69', '70-79', '80-89', '90-99')
pad = np.max([len(i) for i in labels]) * .15
divider = make_axes_locatable(ax1)
ax2 = divider.new_horizontal(size=100%, pad=pad, sharey=ax1)
fig.add_axes(ax2)
N = 10
ind = np.arange(N) # the x locations for the groups
width = 0.35 # the width of the bars
x = [gamma.pdf(i, 1, scale=2) for i in range(N)]
y = [gamma.pdf(i, 5, scale=1) for i in range(N)]
ind = np.arange(N)
ax1.barh(ind, x)
ax2.barh(ind, y)
for loc, spine in ax1.spines.iteritems():
if loc in ['left','top']:
spine.set_color('none') # don't draw spine
for loc, spine in ax2.spines.iteritems():
if loc in ['right','top']:
spine.set_color('none') # don't draw spine
ax1.set_title('Men')
ax2.set_title('Women')
ax1.set_ylim(0, N)
ax2.set_ylim(0, N)
# Name bars
ax1.set_yticks(ind + width)
ax1.xaxis.set_ticks_position('bottom')
ax2.xaxis.set_ticks_position('bottom')
ax1.yaxis.set_ticks_position('right')
ax2.yaxis.set_ticks_position('left')
for tl in ax1.get_yticklabels():
tl.set_visible(False)
ax2.set_yticklabels(labels,
horizontalalignment='center'
)
for i in ax2.get_yticklabels():
i.set_position((-(pad * .12) , 0))
plt.show()
###
However I would like to generalize this function but he space between
the two plots and the position of the labels is giving me a hard time.
In particular, the lines:
pad = np.max([len(i) for i in labels]) * .15
i.set_position((-(pad * .12) , 0))
include two values (.15 and .12) that are completely arbitrary and
defined by trial and error for current labels.
However with different labels:
labels = ('-9000', '10-19', '20-29', '30-39', '40-49',
'50-59', '60-69', '70-79', '80-89', '9-99000')
the values are no longer valid and the final image is no longer properly
aligned.
I know my current approach is not the proper way but due to the
complexity of matplotlib, my very superficial knowledge about it and the
overwhelming documentation this was the closest I could get.
In the end I would like to contribute the final result as something to
be included in the gallery/examples section of the website as I'm
positive that it will be helpful to others.
Any comment or suggestion is extremely welcome.
Cheers,
Renato
