Rotating custom tick labels — Matplotlib 3.1.3 documentation
This might be enough:
<code class="language-python">

<code class="language-python">import matplotlib.pyplot as plt

x = [1, 2, 3, 4]
y = [1, 4, 9, 6]
labels = ['Frogs', 'Hogs', 'Bogs', 'Slogs']

plt.plot(x, y)
# You can specify a rotation for the tick labels in degrees or with keywords.
plt.xticks(x, labels, rotation='vertical')
# Pad margins so that markers don't get clipped by the axes
# Tweak spacing to prevent clipping of tick-labels

How do I get the handles of all open figures in MATLAB - Stack Overflow
There are a few ways to do this. One way to do this is to get all the children of the root object:

figHandles = get(0,'Children');

Or you could use the function FINDOBJ:

figHandles = findobj('Type','figure');

If any of the figures have hidden handles, you can instead use the function FINDALL:

figHandles = findall(0,'Type','figure');
