I have been successfully producing graphics as pngs with matplotlib and
running them as cron jobs with Linux for some time. These graphics used
I recently changed some of the colours, using tuples of RGB values instead
of the standard colors and now the scripts will run from the command line,
but not as scheduled cron jobs and I get the following error:
Unable to access the X Display, is $DISPLAY set properly?
The script then terminates.
Can anyone help me with how to set the display in cron and run Matplotlib
as a cron job.
