Sets the color of the contour level. Has no effect if `contours.coloring` is set to *lines*.

Sets the amount of smoothing for the contour lines, where *0* corresponds to no smoothing.

A data visualized by the sectors of the pie is set in `values`. The sector labels are set in `labels`. The sector colors are set in `marker.colors`

Sets the sector labels. If `labels` entries are duplicated, we sum associated `values` or simply count occurrences if `values` is not provided. For other array attributes (including color) we use the first non-empty entry among all occurrences of the label.

Alternate to `labels`. Builds a numeric set of labels. Use with `dlabel` where `label0` is the starting label and `dlabel` the step.

Sets the label step. See `label0` for more info.

Sets the values of the sectors of this pie chart. If omitted, we count occurrences of each label.

Sets the color of each sector of this pie chart. If not specified, the default trace color set is used to pick the sector colors.

Sets the color of the line enclosing each sector.

Sets the width (in px) of the line enclosing each sector.

Sets the source reference on plot.ly for  colors .

Sets text elements associated with each sector. If trace `textinfo` contains a *text* flag, these elements will seen on the chart. If trace `hoverinfo` contains a *text* flag and *hovertext* is not set, these elements will be seen in the hover labels.

Sets hover text elements associated with each sector. If a single string, the same string appears for all data points. If an array of string, the items are mapped in order of this trace's sectors. To be seen, trace `hoverinfo` must contain a *text* flag.

If there are multiple pies that should be sized according to their totals, link them by providing a non-empty group id here shared by every trace in the same group.

Determines which trace information appear on the graph.

Specifies the location of the `textinfo`.

Sets the font used for `textinfo` lying inside the pie.

Sets the font used for `textinfo` lying outside the pie.
