How can I adjust calibration figure size?

Question

I'm hoping to obtain a larger picture of the calibration figure. The original command is

meas_fitter.plot_calibration()

I tried to use

meas_fitter.plot_calibration(figsize=(10,10))

but that doesn't work. How can I make it bigger? Thanks!

Answer 1

It seems you tried to recreate the plot of the calibration matrix from this tutorial. Which output a plot like something like below when you execute meas_fitter.plot_calibration().

But you want the image above to be larger. If that is the case, then you can change the image size as follows:

import matplotlib.pyplot as plt
fig, ax = plt.subplots(figsize=(10, 10))
meas_fitter.plot_calibration(ax)
