Drawing timing intervals on a time axis

[gingaz]

Hello,

I am looking for solutions to draw a rather very special form of UML Timing Diagram (couldn't find libraries for drawing UML TIming Diagrams):


The diagram displays timeflow on the X axis (1.....NAT). The Y axis displays intervals (Interval 1/2/3), that occur over the time. Intervals may re-occur (Interval 3).
Solid vertical line denotes occurrence of some event (Event 1/2/3) that typically terminates/initiates the interval.
Dashed vertical line denotes the current time.

Would it be possible to draw something like this with JFreeChart?

Thanks!
Gin

It looks like gant chart. You can use something like

private TaskSeriesCollection dataSeries = new TaskSeriesCollection();

JFreeChart defaultChart = ChartFactory.createGanttChart(
"", // chart title
"", // domain axis label
"", // range axis label
dataSeries, // data
true, // include legend
true, // tooltips
false // urls
);

CategoryPlot plot = chart.getCategoryPlot();

DateAxis axis = (DateAxis) plot.getRangeAxis();
axis.setDateFormatOverride(new SimpleDateFormat("dd.MM.yyyy"));
axis.setUpperMargin(0.0f);
axis.setLowerMargin(0.0f);

GanttRenderer renderer = (GanttRenderer) chart.getCategoryPlot().getRenderer();
renderer.setMaximumBarWidth(0.05f);

CategoryAxis axisCategory = (CategoryAxis) plot.getDomainAxis();
axisCategory.setCategoryMargin(0.0f);

// static column keys
dataSeries.getColumnKeys().add("Event1); and so on
