              bgcolor
                  When 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.
              bgcolorsrc
                  Sets the source reference on Chart Studio Cloud
                  for `bgcolor`.
              fgcolor
                  When 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`.
              fgcolorsrc
                  Sets the source reference on Chart Studio Cloud
                  for `fgcolor`.
              fgopacity
                  Sets the opacity of the foreground pattern
                  fill. Defaults to a 0.5 when `fillmode` is
                  "overlay". Otherwise, defaults to 1.
              fillmode
                  Determines whether `marker.color` should be
                  used as a default to `bgcolor` or a `fgcolor`.
              shape
                  Sets the shape of the pattern fill. By default,
                  no pattern is used for filling the area.
              shapesrc
                  Sets the source reference on Chart Studio Cloud
                  for `shape`.
              size
                  Sets the size of unit squares of the pattern
                  fill in pixels, which corresponds to the
                  interval of repetition of the pattern.
              sizesrc
                  Sets the source reference on Chart Studio Cloud
                  for `size`.
              solidity
                  Sets 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.
              soliditysrc
                  Sets the source reference on Chart Studio Cloud
                  for `solidity`.
