Hello,
I am using Linux Mint (latest version) with Sage Math 6.7 64bits . All 3D and 2D graphics are working perfectly but matrix_plot. When I use the example (of help):
matrix_plot(matrix([[1,3,5,1],[2,4,5,6],[1,3,5,7]]))
I got only a vertical axis from 2 to -2 . It happens in Firefox and Chrome.
Can someone help me, please? Thank you in advance.
