Change the unit of x axis in JFreeChart Gantt chart

Question

I\'m a beginner in JFreeChart. I want to change the x axis values of this chart to milliseconds, with 5 ms intervals. I\'ve tried

axis.setTick         


        

Answer 1

Some possibilities to consider:

• Specify the units in the corresponding axis label when creating the chart.

  "TIME (ms)", // range axis label
  

• Use setDateFormatOverride() to change the format of the axis labels, e.g. three-digit values.

  DateAxis axis = (DateAxis) plot.getRangeAxis();
  axis.setDateFormatOverride(new SimpleDateFormat("SSS"));
  

• Use setMaximumDate(), if warranted.

  axis.setMaximumDate(new Date(300));
