I’m trying to hide the Plotly.js created legend for the contour plot.
I set the showlegend: false in the layout object as well as in the trace object, but for some reason it ignores that setting and still draws the legend (although partially visible).
A contour plot legend shows the values that each contour color represents; a symbol plot legend shows the values that each vector color represents. The X–Y plot legend refers to each curve by label and shows the curve’s style.
