How can I maximize my figure on matplotlib python using macOS?

Question

fig, ax = plt.subplots(figsize=(16,8),dpi=100,subplot_kwn {'projection':nccrs.PlateCarree()})
ax.set_global()
plt.subplots_adjust(left=0.04, bottom=0.02, right=0.96, top=0.96)  

# set a figure window's title
fig2 = plt.gcf()
fig2.canvas.set_window_title('Metheoros 1.0')
 mng = plt.get_current_fig_manager()
 mng.Maximize(True)

I Tried this, but didn't work on mac

Answer 1

The first line should have an equals sign in place of the n in subplot_kwn:

fig, ax = plt.subplots(figsize=(16,8),dpi=100,subplot_kw= {'projection':ccrs.PlateCarree()})

You might want to check what you have imported cartopy.crs as, because that may cause problems as well.

EDIT:

So I did quite a bit of digging, and found that in mng has a method called 'full_screen_toggle', so in theory, you could call mng.full_screen_toggle() followed by mng.show() . I tried that, but that seemed to have no effect. I dug through the source code and found that the Mac OS X backend does not have a fullscreen function implemented (as far as I can tell).

That means that you'll have to use a different backend. You can change backends by calling plt.switch_backend('backend') where backend is your desired backend. This function accepts the following arguments:

'pdf', 'pgf', 'Qt4Agg', 'GTK', 'GTKAgg', 'ps', 'agg', 'cairo', 'MacOSX', 'GTKCairo', 'WXAgg', 'template', 'TkAgg', 'GTK3Cairo', 'GTK3Agg', 'svg', 'WebAgg', 'CocoaAgg', 'emf', 'gdk', 'WX'
