RadCartesianChart -- serie-specific tooltips?

[Anders]

Hi telerik,

We are plotting ScatterlineSeries on a RadCartesianChart. Works well.

However, as we plot several series in same chart, our users request a tooltip with the name of series to distinguish them.

I've tried to set the TooltipTemplate of the chart in which case I can get the tooltip for *points* and thought I could use that as a workaround and place Curve Name on each point. However, when I try to bind to an 'enriched' Datapoint I get an error as the points in the serie are ScatterDataPoints (though I've tried to add my 'customized' points, see below).

So I guess I'm missing the point here - or quite a few ;)

First of all, what is the recommended way of providing a serie-specific text on each curve as a tooltip?

And if my approach is not to far off, can you see what I do wrong?

Thanks,

Anders, Denmark

itemsSource.Add(new Rap1DDataPoint(valuesX[i], valuesY[i],curve.CurveName));

public class Rap1DDataPoint : DataPoint
{
    public string CurveName { get; set; }

    public Rap1DDataPoint(double x, double y, string curveName):base(x,y)
    {
        CurveName = curveName;
    }
}

var lineSeries = new ScatterLineSeries
                     {
                         ShowLabels = true,
                         ToolTip = legendHeader,
                         Stroke = serieColor,
                         StrokeThickness = 2,
                         //LegendLabel = legendHeader,
                         //SeriesDefinition = splineSeriesDefinition,
                         ItemsSource = itemsSource,
                         XValueBinding = new PropertyNameDataPointBinding("XValue"),
                         YValueBinding = new PropertyNameDataPointBinding("YValue"),
                         PointTemplate = pointTemplate
                     };

Hello Anders,

We have attached a sample application that demonstrates how you can use the ChartSeries.DisplayName property and bind it in a custom tooltip template to achieve the desired functionality.

Hope this helps.

Dear Admin,
I am binding below PointSeries with collection for XAsix and YAsiX value ,
we need Tool tip with same  XAsix and YAsiX value 
I have created tool tip template.
I used behavior as well ,but in tool tip its not binding the XAsix and YAsiX value
<telerik:RadCartesianChart.Behaviors>
                            <telerik:ChartPanAndZoomBehavior ZoomMode="Horizontal" PanMode="Horizontal" />
                            <telerik:ChartTooltipBehavior Placement="Top" HorizontalOffset="-6" VerticalOffset="1" />
                        </telerik:RadCartesianChart.Behaviors>

ChartMapping is the class of my collection which contain XASIX and YASIX property which we need in Point series collection.  

 <DataTemplate x:Key="ToolTipTemplate"  DataType="{x:Type valueObjects:ChartMapping}">
