Method Details

getPreferredYRange

public double[] getPreferredYRange(ChartModel model)

Description copied from interface: ChartRenderer

Optional Y-range override for autoscaling.

Renderers may return a {minY, maxY} array when the visible range should be based on derived data rather than the model's raw Y-values (e.g. indicators like MACD).

Parameters:

model - the layer model

Returns:

{minY, maxY} or null to use model Y-values

drawData

protected void drawData(Graphics2D g2,
 ChartModel model,
 PlotContext context)

Description copied from class: BaseRenderer
