Although I think it is possible to calculate the bounding box of the all legends automatically, Here is a manual way. from matplotlib.patches import Rectangle l1.get_frame().set_visible(False) # make background frame of legends invisible l2.get_frame().set_visible(False) # make a large backgrou

[Matplotlib-users] imshow + pixels values

2008-10-09 Thread Xavier Gnata
Hi, I can do everything I want with pylab (and even more :) ). I'm only missing one thing: I really would like to have one more option in imshow to get the pixel value of the pixel pointed by the cursor. The backends are showing X qnd Y coordinates. It is fine but I need also to look at the pix

Hi Sebastien, Sorry, I had forgotten about that. I've taken a look at the code that we have ... and it doesn't separate out nearly as much as I had thought. The code that rebuilds the plots is actually pretty complicated and messy ... not so much from a conceptual point of view but in how it

Re: [Matplotlib-users] Lines and columns in legends

2008-10-09 Thread Jae-Joon Lee
The current legend class does not support multiple columns. Eric Wertman once mentioned in this list that he would work on this feature, but I don't know the current status. A (partial) rewrite of the legend class which I plan to support multicolumns is in my TODO list but I haven't started it yet.

[Matplotlib-users] Lines and columns in legends

2008-10-09 Thread José Alexandre Nalon
Hello, Is there an easy way to make a legend with multiple lines and columns? I need 8 plots in the same figure, and the legend takes a lot of space. I believe that if I could orient the legend in multiple lines and columns (say, 2 lines with four columns each), I could save a lot of space, giving
