How to convert long mpl annotations that modify the figure's margins about plotly.py HOT 4 CLOSED

Alright, so, there's no simple way to tell from mpl upon figure opening if the figure is going to need to be bigger. However, the reason you see the long annotation is b.c. you're using mpl in IPython! Try this:

You'll note that the GUI that opens clips off the text just like Plotly would, and that's because that's just where the figure ends!

This may not be a real issue. I might suggest we throw a warning when an annotation runs over the edge of a plot in matplotylib.

What do you think?

from plotly.py.

Oh wow! I did not see that coming!

Randal's figure rendered with .show() yields:

But, with plt.savefig() and within the notebook, the figure's margins are adjusted.

I suspect that plt.savefig() has no affect on the mpl object.

from plotly.py.

I think issuing a warning is the right call.

The warning should make a reference to the Margin object and the Annotation object(s) that caused the issue.

Moreover, maybe we include a few words about how plt.savefig() and IPython NBs adjust the margins so that matplotlylib user can correct their mpl code accordingly.

from plotly.py.

I don't know if the NB actually adjusts anything, the margins are still the same, it's just that the background of the notebook is white, so there's extra canvas to draw on perhaps? i'm not sure how mpl draws in a NB. Nevermind, yeah IPython definitely adjust accordingly.

Yeah, i'll just work on a warning.
