Good morning,
I have an odd problem with saving plot images via the navigation bar
(unsure if it is unique to the navigation bar) if I have added custom
text.
BACKGROUND.
I have a python gui which is used to connect to some hardware as a
diagnosis tool. Its a pyGTK program and on one ui tab there is an
embeded matplotlib plot.
Now some of the signals I plot rather than being a waveform is more of
a collection of flags (16bit but thats a by and by)
eg:
fault
0 = fault1
0 = fault2
1 = fault3
0 = fault4
so for this I can plot this and it will show 2 (possibly changing w.r.t. time).
I then hook in via a onpick event such that if I click on a plot I
essentially do this:
self.figtxt =
self.fig.text(0.79,0.92,'\n'.join(txt),va='top',
bbox=dict(boxstyle='round', facecolor='white',alpha=0.7))
self.plot_marker =
self.plot_area.plot(xdata,ydata,'x',color=event.artist.get_color(),ms=7)
ie I put a cross where someone clicked (for indication) and I also
create a texxbox which lists human readable version of what bits are
set.
Great, really helpful in debugging.
The issue is if you click on the save image icon on the navigation
toolbar it saves the waveform and legend BUT not the additional
content (the cross and the textbox).
any idea as to how todo this?
