i looked at the options of the contour_plot funciton and tried this:
enter code here
contour_plot(pic, (x,-1,1), (z,-1,1), region=region_to_include, contours= 30, plot_points=200, cmap=colormaps.jet, colorbar=True, axes_labels=['$x$ in [m]','$z$ in [m]'], legend_label=['Potential in $V$'])
but that does nto give any effect.
I want to put the unit of my plot there. how can i do that?
