[Matplotlib-users] colorbar() fix limit on Heat map
Hi All, You may remember from my previous post I was having problems plotting a heatmap, however Pete came through for me and made it work. Anyway, I have almost finished what I want to do. The only issue is fixing the colorbar() range limit. Sometimes the my values are 0.01 to 0.2 for example, and other times there 0.01 to 0.99. So what happens it the colorbar() automagically adjusts the gradient according to my values, however I do not want it to do that, I want the graph to be consistantly 0 - 1 (blue - red). I have tried things like colorbar(0,1), however no luck. If you could let me know how to fix the range, I would be very grateful.

[Matplotlib-users] SVG and pdf
Hi! This may be a pdf issue or an SVG issue and have nothing to do with matplotlib. If so, sorry... Whenever I produce a figure with matplotlib and 'crop it' using the axis command the svg comes out fine. However, when I save this svg to pdf using inkscape's 'cairo' backend the part of the data that was 'cropped' becomes visible in the pdf. e.g. if I had plotted data from x = -2 to +10, and then I set the axes to only show the data from +3 to +6, the svg comes out fine, but the pdf shows the rest of the graph leaking out from the axes. I currently have to manually crop my data to prevent this.

Re: [Matplotlib-users] SVG and pdf
Sounds like a Inkscape/Cairo issue to me, if the PDF it converts doesn't match the SVG. That said, SVG is tricky to get right, and we may be able to produce things in a different way that Inkscape will handle correctly. I'll look into this and file a bug with Inkscape and/or Cairo if it turns out to be a bug on their end. Does directly outputting the PDF from matplotlib work as a workaround?

[Matplotlib-users] ticks labels
I am having some trouble getting the ticks and labels on my plot to match what I want and I was hoping that someone here would be able to help. Here are what I want (on the yaxis): logarithmic ticks with major ticks every order of magnitude but labels ONLY every other magnitude. Additionally, I would like the labels to be only the exponent (2 instead of 1e2 or 10^2). For the minor ticks, I want a tick at all 9 values between the major ticks. Here is what I have so far. For the minor ticks, I have subsy=[1,2,3,4,5,6,7,8,9] as an argument for semilogy which seems to work fine. To have labels every other magnitude I used ticker.LogLocator(base=100.0), which gives me the labels where I want them. The two things I have been unable to figure out are how to add a major tick at all of the other magnitudes (those without a label) and how to change the format of the labels so that only the exponent is showing. I'm sure both of these are straightforward, but I have been unable to figure them out. Thanks for your help. -Jeffrey - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users

Hi Jonathan, On earlier versions of Matplotlib, you can use the NavigationToolbar2 class without actually displaying it (the toolbar) in your program. Instead you can use your custom buttons, keypresses, etc, to tie into the class' methods. We've done that with our app, and it works quite nicely. In fact, you can borrow the bits you need from that class to create your own zoom/pan routines.
