Interface IPolarHeatmapDataLabelProviderOptions

Sets the color for data labels. Defaults to axis label color

Draws immediately, set this True when using sub-surfaces for proper data label layering

When set, this provider's labels are drawn immediately after generation (during the series draw), clipped to the returned rect (surface coordinates), instead of in the deferred global text pass. Consequences: clipped labels draw at the series-layer z-order and are excluded from {@link DataLabelLayoutManager} global text layout. Return undefined to skip drawing clipped for a pass. Use getYRangeClipRect to clip to the series' y-axis range (e.g. one grid column).

Flag to enable/disable dataLabel generation. Default true

If this is set it will be used to get text values from metaData, rather than formatting y values. The selector will be called even if the metaData for an index is undefined.

Gets or sets numeric format to use for formatting values to text. For a list of values, see ENumericFormat

Gets or sets the precision to use when formatting values to text.

Sets the text style used for data labels. The style must be set, with fontFamily and fontSize set, in order for text to be drawn.
