How to add to an existing plot a marker for points in the chart
<p>So hello community,
I have a program which includes several functions and they all have 5-6 fix points. On those points i always want to have whether a square or diamond marker style. I can do it in the program but i want to have it in the script so they already appear when i run the program. ANy ideas?</p>

<p>So the answer is described on this website and much more.

<p>basically the command is just:</p>

<pre><code>ax1f1.plot(x, y, marker='s', linestyle='-', color='k')
</code></pre>

python matplotlib marker
