Hello
I would like to do one chart that has somes series
my problem: number of serie is unknow before
could I do some think link that:

Code: Select all

XYSeries seriesS = null;
Hashtable hSeries = new Hashtable();

for (i = 1 >>>>>>>>> S) {
seriesS = new XYSeries("Serie " + i);
hSeries ("" + i,  seriesS );
// add some values here ..
seriesS .add( X, Y);
}

and then

Code: Select all

XYSeriesCollection dataset = new XYSeriesCollection();
seriesS = (XYSeries)hSeries .get("1");
dataset.addSeries(seriesS ); 
seriesS = (XYSeries)hSeries .get("2");
dataset.addSeries(seriesS );

thanks for your helps
best regards

Why not storing the XYSeries in the XYSeriesCollection directly? If you need to access a specific XYSeries later (for getting some data items in) you can access the XYSeries either by XYSeriesCollection.getSeries(Comparable key) or by XYSeriesCollection.getSeries(int index).
