Plotts slightly different size

The three plots are plotted separately and put together in latex. However, for some reason, they are each slightly different in size.

I’m plotting using the following, not sure why it’s the same size.

plt.style.use("science")
plt.figure(figsize=(6, 6))
plt.plot(x, y)
plt.ylabel(ylabel)
plt.xlabel(xlabel)
plt.savefig(savefigname, bbox_inches="tight")
plt.clf()

If you’re using bbox_inches='tight', the result will be shrunk/expanded to fit. If you want a fixed size, then don’t do that.
