Sets the width (in px) of line bounding the box(es). Note that this style setting can also be set per direction via `increasing.line.width` and `decreasing.line.width`.

The scatterpolar trace type encompasses line charts, scatter charts, text charts, and bubble charts in polar coordinates. The data visualized as scatter point or lines is set in `r` (radial) and `theta` (angular) coordinates Text (appearing either on the chart or on hover only) is via `text`. Bubble charts are achieved by setting `marker.size` and/or `marker.color` to numerical arrays.

Sets the unit of input *theta* values. Has an effect only when on *linear* angular axes.

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 plot.ly 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.

Sets the global font. Note that fonts used in traces and other layout components inherit from the global font.

Determines whether or not a layout width or height that has been left undefined by the user is initialized on each relayout. Note that, regardless of this attribute, an undefined layout width or height is always initialized on the first call to plot.
