Axis Scales

[Lou Tylee]

How do you convert the y axis in a plot to a logarithmic scale?

Hello,

In the com.jrefinery.chart.demo.JFreeChartDemoBase class, You'll find the createTimeSeries2Chart() methods which includes the following lines that should interest You :

// [..]
XYPlot plot = chart.getXYPlot();
VerticalLogarithmicAxis vla = new VerticalLogarithmicAxis(range);
plot.setRangeAxis(vla);
// [..]

Hope it helps...

Regards,
Arnaud
