python - Prevent Matplotlib to stretch plot to only bbox of drawing area

Question

Please see below image:

I set the figure size of plt equal to something like (4,6) and set axis to off and margin to zero. Then continue to draw polyline using coordinate array by ax.plot(line[:,1],line[:,0])

after this I don’t use the plt.show() But convert the plot to numpy array which has correct (4,6) size but surprisingly fill the plot by stretched to only bbox of the draw line

How can i see all the unused space of figure?

Is there any flag that i have to change in somewhere in matplotlib?

Any help appreciated

Answer 1

The plot of matplotlib will define the output based on shape and size of drawing not based on the pre-defined figure size,some kind of back-end and front-end, or simply it is a responsive-layout when you resize the window everything will scale else those are passed through linewidth= and ...

then i changed my workflow and problem solved ;)
