Need help graphing 4 curves using Euler's Numerical Method

This is my code now. I need to graph each curve with step size 1, 0.5 and 2. Also, the analytical curve also needs to be graphed. All 4 curves need to go on the same graph. I am receiving the correct output values but it has been a while since I have used python and have forgot how to plot.

The analytical equation is

Where as the equation using the step sizes is

The end of that equation equals the step size.

Values given are g= 9.81, m = 68.1, c = 12.5
