Example 2 with ICustomPaintListener

use of org.swtchart.ICustomPaintListener in project netxms by netxms.

the class PlotArea method paintControl.

/*

public void paintControl(PaintEvent e) {
    Point p = getSize();
    final GC gc = e.gc;

    // draw grid
    for (IAxis axis : chart.getAxisSet().getAxes()) {
        ((Grid) axis.getGrid()).draw(gc, p.x, p.y);
    }
    // draw behind series

        }
    }
    // draw series. The line series should be drawn on bar series.
    for (ISeries series : chart.getSeriesSet().getSeries()) {
