I want to have a scatter plot with dates in x-axis.
Because if I use ChartFactory.getTimeChartView I receive a line graph and the problem is:
ChartFactory.getTimeChartView
You can add custom labels this way:
renderer.addXTextLabel(x, "label");
If you want to keep using the time chart approach then you can do this:
lineRenderer.setPointStyle(style); lineRenderer.setLineWidth(0);
where lineRenderer is a XYSeriesRenderer inside your XYMultipleSeriesRenderer.
