              angle
                  Sets the marker angle in respect to `angleref`.
              angleref
                  Sets the reference for marker angle. With
                  "previous", angle 0 points along the line from
                  the previous point to this one. With "up",
                  angle 0 points toward the top of the screen.
              anglesrc
                  Sets the source reference on Chart Studio Cloud
                  for `angle`.
              autocolorscale
                  Determines whether the colorscale is a default
                  palette (`autocolorscale: true`) or the palette
                  determined by `marker.colorscale`. Has an
                  effect only if in `marker.color` is set to a
                  numerical array. In case `colorscale` is
                  unspecified or `autocolorscale` is true, the
                  default palette will be chosen according to
                  whether numbers in the `color` array are all
                  positive, all negative or mixed.
              cauto
                  Determines whether or not the color domain is
                  computed with respect to the input data (here
                  in `marker.color`) or the bounds set in
                  `marker.cmin` and `marker.cmax` Has an effect
                  only if in `marker.color` is set to a numerical
                  array. Defaults to `false` when `marker.cmin`
                  and `marker.cmax` are set by the user.
              cmax
                  Sets the upper bound of the color domain. Has
                  an effect only if in `marker.color` is set to a
                  numerical array. Value should have the same
                  units as in `marker.color` and if set,
                  `marker.cmin` must be set as well.
              cmid
                  Sets the mid-point of the color domain by
                  scaling `marker.cmin` and/or `marker.cmax` to
                  be equidistant to this point. Has an effect
                  only if in `marker.color` is set to a numerical
                  array. Value should have the same units as in
                  `marker.color`. Has no effect when
                  `marker.cauto` is `false`.
              cmin
                  Sets the lower bound of the color domain. Has
                  an effect only if in `marker.color` is set to a
                  numerical array. Value should have the same
                  units as in `marker.color` and if set,
                  `marker.cmax` must be set as well.
              color
                  Sets the marker color. It accepts either a
                  specific color or an array of numbers that are
                  mapped to the colorscale relative to the max
                  and min values of the array or relative to
                  `marker.cmin` and `marker.cmax` if set.
              coloraxis
                  Sets a reference to a shared color axis.
                  References to these shared color axes are
                  "coloraxis", "coloraxis2", "coloraxis3", etc.
                  Settings for these shared color axes are set in
                  the layout, under `layout.coloraxis`,
                  `layout.coloraxis2`, etc. Note that multiple
                  color scales can be linked to the same color
                  axis.
              colorbar
                  :class:`plotly.graph_objects.scatterpolar.marke
                  r.ColorBar` instance or dict with compatible
                  properties
              colorscale
                  Sets the colorscale. Has an effect only if in
                  `marker.color` is set to a numerical array. The
                  colorscale must be an array containing arrays
                  mapping a normalized value to an rgb, rgba,
                  hex, hsl, hsv, or named color string. At
                  minimum, a mapping for the lowest (0) and
                  highest (1) values are required. For example,
                  `[[0, 'rgb(0,0,255)'], [1, 'rgb(255,0,0)']]`.
                  To control the bounds of the colorscale in
                  color space, use `marker.cmin` and
                  `marker.cmax`. Alternatively, `colorscale` may
                  be a palette name string of the following list:
                  Blackbody,Bluered,Blues,Cividis,Earth,Electric,
                  Greens,Greys,Hot,Jet,Picnic,Portland,Rainbow,Rd
                  Bu,Reds,Viridis,YlGnBu,YlOrRd.
              colorsrc
                  Sets the source reference on Chart Studio Cloud
                  for `color`.
              gradient
                  :class:`plotly.graph_objects.scatterpolar.marke
                  r.Gradient` instance or dict with compatible
                  properties

                  properties
              maxdisplayed
                  Sets a maximum number of points to be drawn on
                  the graph. 0 corresponds to no limit.
              opacity
                  Sets the marker opacity.
              opacitysrc
                  Sets the source reference on Chart Studio Cloud
                  for `opacity`.
              reversescale
                  Reverses the color mapping if true. Has an
                  effect only if in `marker.color` is set to a
                  numerical array. If true, `marker.cmin` will
                  correspond to the last color in the array and
                  `marker.cmax` will correspond to the first
                  color.
              showscale
                  Determines whether or not a colorbar is
                  displayed for this trace. Has an effect only if
                  in `marker.color` is set to a numerical array.
              size
                  Sets the marker size (in px).
              sizemin
                  Has an effect only if `marker.size` is set to a
                  numerical array. Sets the minimum size (in px)
                  of the rendered marker points.
              sizemode
                  Has an effect only if `marker.size` is set to a
                  numerical array. Sets the rule for which the
                  data in `size` is converted to pixels.
              sizeref
                  Has an effect only if `marker.size` is set to a
                  numerical array. Sets the scale factor used to
                  determine the rendered size of marker points.
                  Use with `sizemin` and `sizemode`.
              sizesrc
                  Sets the source reference on Chart Studio Cloud
                  for `size`.
              standoff
                  Moves the marker away from the data point in
                  the direction of `angle` (in px). This can be
                  useful for example if you have another marker
                  at this location and you want to point an
                  arrowhead marker at it.
              standoffsrc
                  Sets the source reference on Chart Studio Cloud
                  for `standoff`.
              symbol
                  Sets the marker symbol type. Adding 100 is
                  equivalent to appending "-open" to a symbol
                  name. Adding 200 is equivalent to appending
                  "-dot" to a symbol name. Adding 300 is
                  equivalent to appending "-open-dot" or "dot-
                  open" to a symbol name.
              symbolsrc
                  Sets the source reference on Chart Studio Cloud
                  for `symbol`.
