when trying to see diskspace with Webadmin, I get the message "Piechart could not be displayed. Please check log file to solve the problem.". I looked into the log messages, searched in the forum and installation troubleshooting guide but my problem seems to be none of the previously reported.
Here's the error and traceback that I find in the log:

The "could not open display" may be related to the fact that there's no display, it's a remote virtual machine.

EDIT: I looked into the matplotlib documentation and found this
matplotlib documentation on http://matplotlib.sourceforge.net/faq/h ... ion-server wrote:Many users report initial problems trying to use maptlotlib in web application servers, because by default matplotlib ships configured to work with a graphical user interface which may require an X11 connection. Since many barebones application servers do not have X11 enabled, you may get errors if you don’t configure matplotlib for use in these environments. Most importantly, you need to decide what kinds of images you want to generate (PNG, PDF, SVG) and configure the appropriate default backend. For 99% of users, this will be the Agg backend, which uses the C++ antigrain rendering engine to make nice PNGs. The Agg backend is also configured to recognize requests to generate other output formats (PDF, PS, EPS, SVG). The easiest way to configure matplotlib to use Agg is to call:
- Code: Select all
# do this before importing pylab or pyplot
import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt
I don't know python but I looked into ''lib/python/omeroweb/webadmin/views.py'' and found something that already said ''agg''.
- Code: Select all
from matplotlib.backends.backend_agg import FigureCanvasAgg as FigureCanvas
import numpy as np
import matplotlib.pyplot as plt
from pylab import *
