Dear list,
apologies for what might be a simple question. I am creating an application
that uses matplotlib for plotting, using the Qt4Agg backend. I can create
the figures without a problem.
However, I wish to save the state of the application, including the graphs.
The complicating factor is that the user may have altered the appearance
of the graphs via a NavigationToolbar.
I have no problems saving the data that makes up the graphs, but how do I
save the properties of the graphs (line colour, linewidth, etc)?
I tried using matplotlib.artist.ArtistInspector(Line2D).properties(). This
gives a dictionary of all the properties. However, when I try to pickle
this I get picking errors:
cPickle.PicklingError: Can't pickle <class 'matplotlib.axes.AxesSubplot'>:
attribute lookup matplotlib.axes.AxesSubplot failed
I am sure that there is an easy way of achieving this, I just can't see it
in the documentation. I appreciate any help the list is able to give me.
regards,
Andrew
