Answer 1

You can do this with the setCategoryMargin() method on the domain axis.

For example with a Category Plot:

CategoryPlot plot = chart.getCategoryPlot();
CategoryAxis domainAxis = plot.getDomainAxis();
domainAxis.setCategoryMargin(0.15f);

You will need to play with different values for the margin to find the correct value for your graph.
