Is there a way to make a contour plot ax.contour line style not a simply dot-dashed but with some hollow markers, like this:
In documentation I see only linestyles parameter with limited set of values, and I know also about a way to tune dash-dot style, like this linestyles=[(0, (7, 3))], but what I looking for is a way to use a marker instead of a simple point in dot-dash style.
