Charts very slow to resize

[deedy]

Some of my plots have many data points.

At some point, these plots become unresponsive.

(1) Are there any settings to plot only a subset of values?

(2) I also suspect that MultiCursor may be slowing things down as well. I tried commenting out (in plot.py):

        cursor = MultiCursor(
            fig.canvas, list(self.pinf.daxis.values()),
            useblit=True,
            horizOn=True, vertOn=True,
            horizMulti=False, vertMulti=True,
            horizShared=True, vertShared=False,
            color='black', lw=1, ls=':')

        self.pinf.cursors.append(cursor)

But that breaks things.

Any thoughts?

Thank you. I was looking for something that will "sparsify" the data, like for every 10 points only plot 1.

Also, is there a way to disable the MultiCursor?

Kind Regards

Mock it! Monkey patch the module and create a Mock class which does nothing.

Thanks I'll try it out
