[Matplotlib-users] Multiple tick labels
Hello all, I feel like this is possible but I am having trouble figuring it out. I want to put extra labels on the ticks on the xaxis like in the upper panel of the figure http://sprg.ssl.berkeley.edu/fast/graphics/socfig1.gif Following http://matplotlib.sourceforge.net/examples/axes_grid/demo_parasite_axes2.html doesn't seem to be the right thing. It seems that I can get the tick values from ax= gca() ax.get_xticks() and from here do the calculations on what the other labels should be (interpolate the spacecraft position). but then how do a create another row of labels with the values that compute? For some reason ax.get_xmajorticklabels()[0].get_text() returns '' Thanks much, Brian -- Brian A.

[Matplotlib-users] Map displayed on a plot
Hello all, I am plotting satellite orbit files and it looks really nice to plot an Earth in the center with the continents on it to orient people to where the spacecraft is. Does anyway know how to do this? All I seem to be able to do is create a whole globe as the figure. In this simple example: from pylab import * r = ndarray(40) r[:] = 3.3 rad = linspace(0, 2*pi, 40) figure() subplot(111, polar=True) plot(rad, r, lw=3) draw() wouldn't it look great to have the earth plotted in the space up to 1.0 (as measured in earth radii)?

Re: [Matplotlib-users] Map displayed on a plot
Thanks, that a step, but how do I tell matplotlib where to then put this map? It needs to be on the current figure with the current axes but between 0 and 1 in radius. Imagine this plot but the black circle instead contains a map of the earth as seen from space in the right viewing geometry. http://plasmasphere.nasa.gov/models/gcpm_v22_eq_kp1.jpg I can work out the geometry and all but putting the map in that black region has me baffled.

[Matplotlib-users] Font size on an axis
Hey all,
wow, this seems like it should be an easy thing but I am not finding
answers in the gallery or searching the documentation.
How does one set the font size on ticklabels and labels for a figure?
I would expect something like plot(arange(11), xfontsize=14) to work
but I am not finding any keywords here for that. what am I missing?
this works for the labels
plot(arange(11))
ax=gca()
ax.set_xlabel('i am x', size=18)
I am trying all sorts of weird things for the ticklabels like
plot(arange(11))
ax=gca()
for val in ax.get_xticklabels():
ax.set_xticklabels(val._text, size=18)
but this must be wrong.
Thanks much,
Brian

[Matplotlib-users] imagsc comparison
Hello all, several of my colleagues and I are 99% sure we are making the change from IDL to python-matplotlib. I have just one issue that I am trying to work out that I need to solve. We are so far really impressed and looking forward to the change. I have seen discussion on this list about imagesc and imshow but none of them have quite answered the questions. In IDL we spent way too much time writing an clone that is still not full featured: http://people.bu.edu/balarsen/IDLdoc/imagesc.html I have data of probability distributions which have an X and Y array associated with the axes of the 2-d distribution (image). What I don't see how to do in any easy fashion is plot this data in a imshow() manner with the axes correct (which are unevenly distributed and need to be plotted on a log axes). This can be done with contourf(X,Y,Z) but this has a few issues: - I dont see how to do a log axes on a contour - contour is the wrong plot as the inherent smoothing that a contour does is highly undesirable. Using matlab imagesc one can easily make plots similar to: http://img269.yfrog.com/i/2dprob.png/ Imagine taking the above plot and make the pixels different sizes so that each pixel has identical counting statistics. Now assume that one wanted the Y-axis to be plotted in log. Anyone have any thoughts or toy examples?
