[Matplotlib-users] How do you use ticklabel_format?
Hello,
I'm trying to make a simple plot that doesn't use scientific
notation for the x axis since the axise only goes from 1 to 1600. I
tried using ticklabel_format like this:
from pylab import *
l, cltt = loadtxt('ABF_20_20.dat',unpack=True)
semilogx(l, cltt)
xlim(1,1600)
ax = gca()
ax.ticklabel_format(style='plain',axis='x')
show()
I get this error This method only works with the ScalarFormatter.
which seems to be the error refered to in the documentation. However,
I'm not sure how to fix the problem? Is there way to use this
ScalarFormatter some how? Did I code it wrong?
If anyone knows how to get the xaxis to not display scientific
notation this would be helpful. Thanks.
Joseph Smidt

Sebastian,
Thanks, your hint worked.

from pylab import *
a = arange(1600)
plot(a,a)
xscale('log')
from matplotlib.ticker import ScalarFormatter
ax = gca().xaxis
ax.set_major_formatter(ScalarFormatter())

[Matplotlib-users] Artifacts In Transparent Contour Plots?
I am making contourf plots with some transparency as I want to eventually overlay such plots. When I plot such plots I see artifacts or lines that shouldn't be there as seen here: http://josephsmidt.googlepages.com/ex.png Is this a bug or am I plotting incorrectly? My script is here: http://josephsmidt.googlepages.com/plotex.py and the data needed for the plot is here: http://josephsmidt.googlepages.com/exCHI.txt However, the relevant part of the code for plotting I'll just cut and paste here: levels = [x0, x1, x2, x3] contourf(Y,X,transpose(CHI),levels,alpha=0.7) show() Thanks.

Re: [Matplotlib-users] Artifacts In Transparent Contour Plots?
Thanks a lot. The code you mentioned:
cs = contourf(Y,X,transpose(CHI),levels,alpha=0.7)
for c in cs.collections:
c.set_edgecolors('none')
worked great and the extra lines are gone.

PS. Good luck with this issue. I'd help but I'm not that good.

[Matplotlib-users] Possible To Contour Around 1-Sigma Curves?
I have a function on a 2d grid that looks like a skewed mound. I would like to make a contour plot where each contour represents each sigma, or confidence interval. I.e. Is there a straight forward way to make such a contour plot where it is then easy to say: This line is 1-sigma or 68% confidence interval, this line is 95% confidence interval, etc... Such plots look like this: http://lambda.gsfc.nasa.gov/product/map/current/pub_papers/threeyear/parameters/images/Med/ds_f07_PPT_M.png where the first region of each graph is the on sigma or 68% confidence interval and the second line is the 95% confidence interval.

[Matplotlib-users] Remove box around legend?
I see lots of examples on how to play around with the legend, adding columns, shadow, etc...Is there a way to remove the box so that all you see are the items of things being plotted with no box around them? Also, keeping the box but removing the black outline around the box is good enough since it would look like there is no box.

[Matplotlib-users] Add units to plots?
I have several plots where the scientific notation exponential overflows to the top of the plot like this: http://matplotlib.sourceforge.net/examples/pylab_examples/plotfile_demo.html. Is there any way to add units to this? So that, if I wanted, the units would show up in the overflow as: 1e8 m^3 , for meters cubed? Also, is there an easy way to add units to the numbers on the x or y axis in general? Thanks.

[Matplotlib-users] Another Gnuplot style question
Okay, I am another gnuplot user trying to migrate over to matplotlib. I like what I see, but there are a couple things that are very easy to do in Gnuplot that I can't figure out how to do with matplotlib. I have a file with 3 columns of data called data.txt that looks like: 0. 1. 1.0 0.0634 1.0655 1.1353 0.1269 1.1353 1.28899916094 0.1903 1.2097 1.46345358199 0.2538 1.2889 1.6615188369 0.3173 1.3734 1.88639043926 ... I can plot this data, 2 versus 1 and 3 versus 1, very easily on the same plot, with a legend, with log y values, and only for the xrange between 2 and 3 with gnuplot: set log y set xrange[2:3] plot 'data.txt' u 1:2 w l t 'apples', 'data.txt' u 1:3 w l t 'oranges' Now, how do I do that same thing with matplotlob? Ie: 1. Both graphs overlayed on the same plot. 2. Semilogy. (log y values), 3. Only ploy for x in the range 2-3. 4. Legend for the two graphs on same plot. I have spent time looking through the documentation but I can't find anyway to do this is any straightforward way. plotfile() looks promising, but I can't seem to make it do the above. Thanks in advance.
