Create series dynamically
posted

Hello!

I'm new to DataChart, and have a following question.

I need to create a line chart with several series, like this:

Series1: { X: 0, Y:0; X:1, Y:5; X:2,Y:10; X:3, Y:15 }
Series2 may be like this: { X: 10, Y:10; X:11, Y:15; X:12,Y:110; X:13, Y:115 }
Series3 may also be something different.

Normally I'd do it like this:

for( i = 0; i < 3; i++ )
{
  series = new LineSeries();
  points = new points();

  for( // all points )
  {
    point = new point;
   // ....
    points.Add( point );
  }

  series.ItemSource = points;
  chart.Series.Add( series );
}

The question is -- what do I do with the XAxis? In the samples there is a line:

xmXAxis.ItemsSource = data;

But here it's not a simple data, it's an array of arrays of points. If I don't execute this line, the chart comes out empty. So, how whould I do this? Or would I better be off with WebChart in tis case (but what about performace?)?

Thanks in advance!
