Sets the area to fill with a solid color. Use with `fillcolor` if not *none*. scatterpolar has a subset of the options available to scatter. *toself* connects the endpoints of the trace (or each segment of the trace if it has gaps) into a closed shape. *tonext* fills the space between two traces if one completely encloses the other (eg consecutive contour lines), and behaves like *toself* if there is no trace before it. *tonext* should not be used if one trace does not enclose the other.

Sets a reference between this trace's data coordinates and a polar subplot. If *polar* (the default value), the data refer to `layout.polar`. If *polar2*, the data refer to `layout.polar2`, and so on.

Sets the source reference on Chart Studio Cloud for  theta .

The scatterpolargl trace type encompasses line charts, scatter charts, and bubble charts in polar coordinates using the WebGL plotting engine. The data visualized as scatter point or lines is set in `r` (radial) and `theta` (angular) coordinates Bubble charts are achieved by setting `marker.size` and/or `marker.color` to numerical arrays.

The data visualized by the radial span of the bars is set in `r`

Sets where the bar base is drawn (in radial axis units). In *stack* barmode, traces that set *base* will be excluded and drawn in *overlay* mode instead.

Shifts the angular position where the bar is drawn (in *thetatunit* units).

Sets the bar angular width (in *thetaunit* units).

Determines how bars at the same location coordinate are displayed on the graph. With *stack*, the bars are stacked on top of one another With *overlay*, the bars are plotted over one another, you might need to an *opacity* to see multiple bars.

Sets the gap between bars of adjacent location coordinates. Values are unitless, they represent fractions of the minimum difference in bar positions in the data.

Area traces are deprecated! Please switch to the *barpolar* trace type. Sets the radial coordinates for legacy polar chart only.
