Why Are My matplotlib Images Blank?

Troubleshooting Blank Images in matplotlib's Savefig

When attempting to save matplotlib plots as images, users may encounter blank output. To resolve this issue, consider the following factors:

1. Figure Structure: Examine the code structure related to subplot creation. Ensure that the specified indices for plt.subplot() are consistent and correspond to the subplots being created. Adjust these indices accordingly.
2. Figure Display and Saving Sequence: Pay attention to the order of commands. To avoid saving an empty figure, it is recommended to call plt.savefig() before plt.show(). Alternatively, save the figure object using plt.gcf() before plt.show() and then save the figure at any desired time.
3. Blank Image Indicator: In your code, tessstttyyy.png is blank because it is saving the new figure created after plt.show(), which contains no plots.
