OptionalbgcolorWhen there is no colorscale sets the color of background pattern fill.
Defaults to a marker.color background when fillmode is overlay.
Otherwise, defaults to a transparent background.
OptionalfgcolorWhen there is no colorscale sets the color of foreground pattern fill.
Defaults to a marker.color background when fillmode is replace.
Otherwise, defaults to dark grey or white
to increase contrast with the bgcolor.
OptionalfgopacitySets the opacity of the foreground pattern fill.
Defaults to a 0.5 when fillmode is overlay.
Otherwise, defaults to 1.
OptionalfillmodeDetermines whether marker.color should be used
as a default to bgcolor or a fgcolor.
OptionalshapeSets the shape of the pattern fill. By default, no pattern is used for filling the area.
OptionalsizeSets the size of unit squares of the pattern fill in pixels, which corresponds to the interval of repetition of the pattern.
OptionalsoliditySets the solidity of the pattern fill. Solidity is roughly the fraction of the area filled by the pattern. Solidity of 0 shows only the background color without pattern and solidty of 1 shows only the foreground color without pattern.
'Sets the pattern within the marker.
