What do you mean by selecting Fig? Please be more specific.

Hi,
Sorry - this was an automated error code generated by Spyder, and I presed OK before reading it properly.
The error occured when creating a plot using Matplotlib within Spyder. The code was as follows:

import matplotlib.pyplot as plt
fig = plt.figure(figsize=(20, 10))

A variable appeared in Variable Explorer called fig. I double clicked on it to examine, and this caused an error.
I've added a screen shot to this note.

Let me know if there is anything else I can provide
Thanks
