In the Spyder IDE, I want to keep the inline console plotting (I don't want separate windows to spawn for each plot), but I want to programmatically disable plotting, i.e. in different cells.

In my workflow I need to plot a few simple graphs, and then generate figures and save them as video frames (many thousands). My frames are created by loading a jpg image, and then overlaying some annotation i.e.;

for jpg_path in path_list: img = mpl.image.imread(jpg_path) ax.imshow(img) ax.text(etc...) fig.savefig(etc...)

I want to keep the inline backend; %matplotlib inline.

But turn off plotting with something like plt.ioff().

But plt.ioff()only works with i.e. %matplotlib qt backend, not inline!

I've had several cases where I forget to change to %matplotlib qt (because it's not a python command and I have to enter it into the console seperately) and then plt.ioff() - resulting in 10000 images being posted in the console, freezing my machine.

Ok I think I found an answer, thanks to this answer;

The key was the python command for the line magics get_ipython().run_line_magic('matplotlib', 'inline'). I created a context manager to wrap my video frame for-loop; 

from IPython import get_ipython class NoPlots: def __enter__(self): get_ipython().run_line_magic('matplotlib', 'qt') plt.ioff() def __exit__(self, type, value, traceback): get_ipython().run_line_magic('matplotlib', 'inline') plt.ion()

Or is there a better approach?
