[Matplotlib-users] Best way to set scales bounds to appropriate values

Hi, I'm a matplotlib newbie. An example is worth a thousand words: In [1]: matplotlib.__version__ Out[1]: '0.99.3' In [2]: a, b, x = np.zeros(10), np.ones(10), np.arange(10) In [3]: plot(x, a); plot(x, b) Well all I see is an empty plot with the two horizontal lines at y=0 and y=1 covered by t

[Matplotlib-users] No autoscaled and correctly tickered logarithmic y-axis after zoom

Dear Matplotlib-Users. After changing the scaling from the y-axis from default to semilogy the tickers were not updated anymore automatically when a zoom is applied. Even after deep searches within the ticker API as well as the mail archive list I could not find an appropriate solution for this

[Matplotlib-users] Fancy labelling / tickering of isolines

Dear Matplotlib-Users. I try to generate some 2d plot with dimension log10(p)-h from refprop. For the isolines (isentropes, isotherms, isochores etc.) I was successful but adding labels to these isolines were quite discouraging until now. Please have a view on the screenshot to have an idea of

[Matplotlib-users] Stair plot

Hi: Any suggestion for making a stair plot in Matplotlib (like the stairs function in Matlab)? The attached figure is the output of the following Matlab commands: x = 0:10; stairs(x); I guess it is a matter of using a zero-order hold interpolation rather than linear interpolation between the po

Can you please see the code below and let me know why the png figure comes out empty (it only contains the x-axis, does not contain the scatterplot). The pdf file has no such problems. I have tried saving another usual line plot in .png format and I had no problems. Does this have to do with scatt

Tom, I just went through this, though with version 1.01 of mpl, so it may be different. You can read the very long thread at: http://www.mail-archive.com/matplotlib-users@lists.sourceforge.net/msg20031.html Those who maintain mpl don't think there is a memory leak. What I found was that imsh
