Re: [Matplotlib-users] setting x tick labels with matshow

[Sterling S. <sm...@fu...>]

Kelson,

Reading the documentation of matshow 
help(matshow)
reveals that it passes most keywords to imshow.  Documentation of imshow 
help(imshow)
says it has an extent keyword to indicate the x and y ranges (instead of the array index).  So something like (untested)
matshow(<your matrix>,extent=(left,right,bottom,top)) #where left is probably min(x), right is max(x), etc.
should work.

The x dimension is a series of floats, but they don't correspond to the data matrix cell index values (0,1,2…) that make up what matplotlib obviously thinks are the x values for the plot.  Is there a way that I can set the x tick labels so that they will be laid out and formatted in the normal way for numbers on the x-axis?  It would be great if they also scaled in the normal way when the plot is manipulated in the little gui window.
