I’ve been having issues with a web system I coded for a while now and couldn’t find a solution that worked to my satisfaction to eliminate the need of a Xvnc running to provide a virtual DISPLAY to run some commands to plot data using pylab.
Finally, today, I found the solution here and I want to share it.
import matplotlib matplotlib.use('Agg') # Must be before importing matplotlib.pyplot or pylab! import matplotlib.pyplot as plt fig = plt.figure() plt.plot(range(10)) fig.savefig('temp.png')
The solution, here, is the Agg option as the “device” to be used to plot files.
Solution in place, and I can now eliminate the requirement for Xvnc from my code and all the issues that came with it are also automatically gone.
So, here’s the code for Pylab:
import matplotlib matplotlib.use('Agg') # Must be before importing matplotlib.pyplot or pylab! import pylab pylab.plot(range(10)) pylab.savefig('temp.png')
