savefig('filename.png') saves a blank image in the folder

Question

fig, ax = plt.xticks(datechange_index,datechange)
datacursor(display='single')
plt.ylabel('Temp in Kelvin')
plt.figure(figsize=(200,20))
plt.savefig('temp_plot.png')
plt.show()

The block of code above is what I tried to save a plot in matplotlib. However, it ends up generating a blank image. I've tried a few solutions commonly suggested (which is why I have plt.savefig now above plt.show(), to no avail.

Answer 1

@BigBen has answered this question:

plt.figure(figsize=(200,20)) creates a blank figure, right before you savefig

which explains why the OP initially was showing a blank figure.

Also, @BigBen went on further to flag that the naming convention used in the variables for the xticks function was misleading.
