Hello,

I am using matrix_plot to display my 2 dimensional array of data. Is there a way to change the tick mark values? Right now they are set to the index values of the matrix.

Also see this example from Matlab Stackoverflow

I was already trying to overload matplotlib keyword extent Example:

matrix_plot(mat, extent=[horLeft, horRight, verTop, verBottom])

I modified my sage source code to do solve this for me. I had to modify matrix_plot.py.

Can you tell us what you did? It would be great to add something like this to Sage - see for instance http://trac.sagemath.org/sage_trac/ticket/2189 for an attempt that never quite got in because of the resizing of the matrices in corner cases.

to whom may I send the patch to review it?

I think you can email to sage-devel ( https://groups.google.com/forum/?fromgroups#!forum/sage-devel ) if you don't want to create an account and submit to the trac website.
