Methods

Modifier and Type	Method and Description
Point	drawOutput(Graphics g, int outputIdx, Object values, Color color, Stroke stroke, IIndicatorDrawingSupport indicatorDrawingSupport, List<Shape> shapes, Map<Color,List<Point>> handles) This method will be called once for every output marked as drawnByIndicator every time the chart surface needs to be redrawn

Method Detail

drawOutput

Point drawOutput(Graphics g,
               int outputIdx,
               Object values,
               Color color,
               Stroke stroke,
               IIndicatorDrawingSupport indicatorDrawingSupport,
               List<Shape> shapes,
               Map<Color,List<Point>> handles)

This method will be called once for every output marked as drawnByIndicator every time the chart surface needs to be redrawn

Parameters:

g - graphical context

outputIdx - index of the output parameter

values - array of values (int[], double[] or Object[] depending of the type of the output). Array may be empty or null if data is not yet available.

color - color selected when the indicator was added

stroke - stroke selected when the indicator was added

indicatorDrawingSupport - provides information about candle positions, indexes, etc

shapes - graphical shapes can be added to this list. This makes it possible to show correct popup when user right-clicks one of the shapes in this list on chart

handles - coordinate points with their corresponding colors can be added to this list

Returns:

X-Y coordinates of last point drawn. This point will be used when drawing last value marker on chart. The marker will not be drawn if null is returned.
