This looks like a duplicate of #2900

Sorry, not a duplicate after all. #2900 is describing a different bug, but the description contains mention of this warning.

I've moved all the graph generation code to the web_ui module and this seems to get rid of the matplotlib warning message. I also took the opportunity to move the mdashboard code into the web_ui, and model modules. It seemed unnecessary to have a separate module. See:

Thanks for investigating on this. I think matplotlib has been quite a problem for us. I am thinking about changing to Open flash chart (​http://teethgrinder.co.uk/open-flash-chart/) but am not sure when I will get around to do it. Does anyone have any experience with it? I hope it's easy to move. Then we don't really need to numpy and matplotlib to use TracMetrix.

Please try the new version. This problem should go away.
