I'm trying to plot the graphs of some mathematics equations using Sympy.

The graphs representing the equations look fine but when I checked the indexes on both the X-axis & the Y-axis, they are not equal. In other words, the Y-axis might represent twice the length of the X-Axis. You can check the picture below for a better visual understanding.

So my question is: How can we adjust the coordinate plane so that the X-axis and Y-axis are equal in length?

Thank you

Code :

formula = x**2 - 5*x   9
plot( formula )

There is the aspect_ratio keyword argument that allows you to achieve what you want by specifying aspect_ratio=(1, 1) (same aspect ratio on both axis). You might also want to play with xlim and ylim to center the view:

formula = x**2 - 5*x   9
plot( formula, aspect_ratio=(1, 1), xlim=(-2.5, 7.5), ylim=(0, 10) )
