[Matplotlib-users] matshow / imshow with date-axis
Hi, is it possible to perform a surface plot a NxM matrix with date-axes? Similar to plot_date for 1D-Plots. The dates are available as an N-sized (or M-sized) array of float values. At the moment, I am using imshow or matshow for the color plots, but the only way I found to manipulate the axes is the 'extent' keyword argument, which is not sufficient in this context. Any hints?

Micha Hi Micha, Did you already set the date-xaxis by hand? - for axes 'ax' using e.g. ax.xaxis_date(tz=None) ax.yaxis_date(tz=None) I would hope that extent and this together yield your aim, but I'm not so familiar with date-axes. Kind regards, Mattthias -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.

Hi Matthias, Thanks for the help. The problem is, however, that the 'extent' parameter only manipulates the range of the (integer) values on the axis. Before setting the *axis_date property, I need to set the axes data to arrays of (non-equidistant) floats.
