Hi All, I use IReport to create jasper. the customizer class adds the secondary datasets. The issue is that the tool tip is not shown for the newly dataset. Code: public void customize(JFreeChart chart, JRChart jasperChart) { XYPlot plot = chart.getXYPlot(); XYLineAndShapeRenderer rend1 = (XYLineAndShapeRenderer) plot.getRenderer(); rend1.setShapesVisible(false); rend1.setPaint(new java.awt.Color(0, 100, 255)); ... ... TimeSeries overlaySeries = new TimeSeries(seriesName, Minute.class); ... ... ...
