Determines whether of not the contour level attributes at picked by an
algorithm. If “true”, the number of contour levels can be set in
ncontours. If “false”, set the contour level attributes in
Determines the coloring method showing the contour values. If “fill”,
coloring is done evenly between each contour level If “heatmap”, a
heatmap gradient is coloring is applied between each contour level. If
"lines", coloring is done on the contour lines. If “none”, no coloring
is applied on this trace.
Sets the number of contour levels.
