Subplot problem - plots are on top of each other?

I have a script that creates 2 plots. I would like them to be next to each other in a typical subplot form. However, when I run this script, it only plots the second plot and the axes are messed up, such that it looks like it's layering plots on top of each other perhaps. If I take out the subplot syntax and run them as separate figures, they look fine. It's only and issue when I try to use subplot. I cannot figure out what the problem is. I know my code isn't going to win any code beauty pagents, but this is an odd problem I cannot figure out. I'm running 2018a. Thank you all in advance.

subplot(1,2,1);
h1 = axes;
The subplot() call creates an axes that covers half of the figure. The axes() call creates an axes in the default position, covering the figure. These are not the same axes. You should use
h1 = subplot(1,2,1);
