I would like create 10 plots displayed on 2 lines that will stay in the same place on the jupyter notebook during the loop and new There is a clear figure command, and it should do it for you: (121) / subplot(122) for the same plot, different position. by having it be the last thing in a cell). I now If you have a list of images and want to animate through them, you can use something like this: from keras. import matplotlib. figure(). barplot( code for plot 1 ) # plot 1 plt.
