Question

I am using JFreeChart, and I want to remove the left and right spaces in my waterfall chart.

Here is what my chart looks like right now with the red squiggles to demonstrate the space I want to remove.

Any idea how to remove these spaces?

Answer 1

Because ChartFactory.createWaterfallChart() instantiates a CategoryAxis, simply set the relevant margins:

CategoryAxis domainAxis = plot.getDomainAxis();
domainAxis.setLowerMargin(0);
domainAxis.setUpperMargin(0);

Addendum: Note that negative values make the margin smaller, as illustrated here.

domainAxis.setLowerMargin(-0.05);
domainAxis.setUpperMargin(-0.05);
