ClassCastException: com.jrefinery.data.XYSeriesCollection

[VK]

jFreeChart 0.9.4 :

I'm trying to create a CombinedXYPlot using two subplots as follows :

...
CombinedXYPlot plot = new CombinedXYPlot(
new HorizontalDateAxis("Date"),
CombinedXYPlot.VERTICAL);

for (int i = 0; i < m_XYPlotArray.size(); i++) {
plot.add((XYPlot)m_XYPlotArray.get(i), 2);
}
...

The first subplots has two series and the second one has one series populated as :

XYSeriesCollection dataset = new XYSeriesCollection();

dataset.addSeries(...);

The subplots seem to be added correctly, but the following line raises a ClassCastException:

-> ChartUtilities.saveChartAsPNG(m_file, m_chart, 400, 300, m_info);

[[java.lang.ClassCastException: com.jrefinery.data.XYSeriesCollection]]

In debug mode, the m_file/m_chart and m_info objects display expected values.


Am I missing something?

Thanks,
VK

It sounds like a bug. Can you post a small sample application that replicates the problem?
