Methods

setShading(scheme)

Sets the shading scheme of the renderer

Parameters:

Name	Type	Description
scheme	array	single object or array of objects denoting shading Properties Name Type Argument Description primary String <optional> left series for comparison; if omitted, use chart.dataSegment[i].Close secondary String <optional> right series for comparison; if omitted, use first series in the seriesMap color String <optional> color in hex, rgb, rgba, etc to shade between primary and secondary greater String <optional> color in hex, rgb, rgba, etc to shade between primary and secondary if primary is greater in price than secondary lesser String <optional> color in hex, rgb, rgba, etc to shade between primary and secondary if primary is lesser in price than secondary Note: if scheme.greater or scheme.lesser are omitted, scheme.color is used. At a bare minimum, scheme.color is required. It is not required if scheme.greater and scheme.lesser are supplied. If scheme.primary is omitted, the shading will only occur if the series share the same axis as the chart.dataSegment[i].Close. If shading cannot occur for any reason, series lines will still be drawn.

Example

renderer.setShading([
	{primary:'ibm', secondary:'ge', greater:'green', lesser:'red'}, // switches shading based on crossover of values
	{primary:'t', secondary:'intc', color:'blue'}, // color always blue between them regardless of which is higher or lower
	{secondary:'t', color:'yellow'}, // compares masterData with the named series
	{color:'yellow'} // automatically shades between master and the first series
