Set true if the paletting does not depend on the visible Range. This prevents the palette being recalculated if only the visible range changes.
Called when the PaletteProvider instance is attached to a RenderableSeries. Use this to be notified when attached and keep a reference to the parent series
Called when the PaletteProvider instance is detached from a RenderableSeries.
Called by SciChart and may be used to override the color of filled polygon in various chart types.

true if paletting should be forced to run. If this exists and returns false, the existing paletting state is reused if possible. If this does NOT exist, the palette will be recalculated on every render. This default will change in v4. Use this to force the palette to be recalculated if some external parameter to it changes.

A Default Palette provider is applied to the BaseRenderableSeries.paletteProvider property in the constructor however all its functions such as DefaultPaletteProvider.overrideFillArgb, DefaultPaletteProvider.overrideStrokeArgb etc... are set to undefined. This allows a user to do quick one-line paletteproviders in vanilla Javascript like this:
const series = new FastLineRenderableSeries(wasmContext); series.paletteProvider.overrideFillArgb = (xValue, yValue, index) => { return yValue > 0 ? parseColorToUIntArgb("white") : undefined; }
