Tick labels in a matrix plot

I want to plot the following matrix m with k and l in {-2, ..., 2}:

m = [[k+l for k in range(-2,3)] for l in range(-2,3)]

with matrix_plot:

m_plot = matrix_plot(m, origin='lower')

The ticks on both axes are automatically set to {0 , ... , 5}, but I want the ticks to be {-2, -1, 0, 1, 2} on both axes. I could not figure out how to do this.

Hello,

You could use the option ticks and tick_formatter as follows

sage: matrix_plot(m, ticks=[[0,1,2,3,4],[0,1,2,3,4]], tick_formatter=[[-2,-1,0,1,2],[-2,-1,0,1,2]])

These are documented in the function plot and you can access the help with

sage: plot?
