[Solved] Multi-Lines with SeriesMappings?

[Enill]

Hi,
is it possible to have multiple lines in a same chart using different seriesmapping object?

To be more clear, i have 2 "List<StructXY>" where "StructXY" is a structure with two field(double x, double y).

i have a "List<List<StructXY>>" collection and i want to bind 2 different seriesmapping(to draw two independant lines) in my chart based on the x and y value of eah collection.

Thanks in advance if you can give me a simple working C# example.

Here is my test project(The reference to collectionindex = 1 just doesnt work at all):

namespace seriesmapping_test
{
    public partial class MainPage : UserControl
    {
        public struct structXY
        {
            public double valueX { get; set; }
            public double valueY { get; set; }
        }

        public MainPage()
        {
            InitializeComponent();

            RadChart rc = new RadChart();
            List<List<structXY>> lstMain = new List<List<structXY>>();
            List<structXY> lst1 = new List<structXY>();
            List<structXY> lst2 = new List<structXY>();

            SeriesMapping sm1 = new SeriesMapping()
            {
                SeriesDefinition = new LineSeriesDefinition()
                {
                    ShowItemLabels = false
                }
            };
            sm1.CollectionIndex = 1;
            sm1.ItemMappings.Add(new ItemMapping("valueX", DataPointMember.XValue));
            sm1.ItemMappings.Add(new ItemMapping("valueY", DataPointMember.YValue));

            SeriesMapping sm2 = new SeriesMapping()
            {
                SeriesDefinition = new BarSeriesDefinition
                {
                    ShowItemLabels = false
                }
            };
            sm2.CollectionIndex = 1;
            sm2.ItemMappings.Add(new ItemMapping("valueX", DataPointMember.XValue));
            sm2.ItemMappings.Add(new ItemMapping("valueY", DataPointMember.YValue));

            rc.SeriesMappings.Add(sm1);
            rc.SeriesMappings.Add(sm2);

            for (int i = 0; i < 100; i++)
            {
                lst1.Add(new structXY() { valueX = i, valueY = i });
                lst2.Add(new structXY() { valueX = i, valueY = i ^ i });
            }

            lstMain.Add(lst1);
            lstMain.Add(lst2);

            rc.PaletteBrushes.Add(new SolidColorBrush(Colors.Red));
            rc.PaletteBrushes.Add(new SolidColorBrush(Colors.Green));
            rc.ItemsSource = lstMain;

            LayoutRoot.Children.Add(rc);
        }
    }
}

Hi Enill,

I reviewed your code and I found two possible issues:

1. CollectionIndex is set to 1 for both series definitions
2. valueY = i ^ i -- this always sets valueY with 0, try changing it to i*i or i*5

Hi,
actually i noticed that i didnt posted the good code block, i apologies.

The correct code block did'nt had the i ^ i , it was for a test purpose.

Also, as you pointed, both collection were pointing to CollectionIndex = 1, it was my mistake, lack of awareness.

Thanks you!
