How to programmatically select pan/zoom in pyqt/matplotlib navigation

Question

I have a pyqt4 matplotlib application and I would like the figure to start out (default) to the pan zoom mode when the application opens. I can't find any example or clue from the documentation on how to do this programmatically.

Also along this same line how would I enable the shortcut keys in my application (http://matplotlib.sourceforge.net/users/navigation_toolbar.html)

Thanks for any suggestions.

I had a similar issue and in my case I solved it by using toolbar.zoom():

import pylab

plt.Figure()
thismanager = get_current_fig_manager()
thismanager.toolbar.zoom()

In that case the figure will appear with the zoom tool already selected

My setup as a pyqt4 application is a little different than what you describe but you got me on the right track. – Colin Talbert Apr 13 '12 at 19:36

The solution I ended up with was:`code`self.mpl_toolbar = NavigationToolbar(self.map_canvas, None) self.mpl_toolbar.pan()'code' – Colin Talbert Apr 13 '12 at 19:38
Thanks! It's frustrating when something so simple can take so long to find. – Colin Talbert Apr 13 '12 at 19:39
If you're using `import matplotlib.pyplot as plt` , use this one liner `plt.get_current_fig_manager().toolbar.pan()` to default to pan – coreyb Sep 20 '18 at 14:47
