JFreechart X and Y axis scaling

It's possible to set the axis scale values in jfreechart? For example, I'd want X-axis scale 10 and Y-Axis scale 1.

Solution

  • You set the TickUnit, if you are using an XYPlot try this

    XYPlot plot = chart.getXYPlot();
NumberAxis xAxis = (NumberAxis) plot.getDomainAxis();
xAxis.setTickUnit(new NumberTickUnit(10));

NumberAxis yAxis = (NumberAxis) plot.getRangeAxis();
yAxis.setTickUnit(new NumberTickUnit(1));
