Overlaying grid over contour graph

📊 Plotly Python
1

Hi everyone! First one, I’d like to figure out is it possible to overlay grid over contour graph (problem illustrated on the first attached image). And second one, when I set Histogram2dContour.contours.coloring=‘none’ I can disable contour graph using legend (second attached image) and with other values I can’t do this (there is no trace0 on the first attached image’s legend). Is it possible to dissable contour graph using ‘heatmap’, ‘lines’ or ‘fill’ values of coloring parameter?

Overall I want to use Histogram2dContour.contours.coloring=‘heatmap’ with ability to dissable contour graph using legend and grid which overlaying contour graph

Any help is highly appreciated.
