I have a contour plot and I want to draw the zero isoline / contour line at value 0 of another plot on top of it to be able to compare the two plots:
(For this example the curve was added manually.)
1.: Is there a way to overlay contour plots?
2.1: Can I draw points/lines onto a contour plot?
2.2: Can I extract the contour line that plotly found into an array or similar? I tried extracting it with marchingsquares-isocontours.js but that gave me unsatisfactory results, with interrupted or missing lines.
The ranges of my axes are the same for every sample.
