Enable Tooltips on XY Dataseries

Is there a tutorial on how to enable tooltips on an xy dataseries so they display the values of a given point?  Like in the key features of the wpf chart documentation?

 

Hi,

We can show tooltip on C1WpfChart in the following manner:

The current DataPoint instance that provides information about the point.
When using data binding it makes it easier to display this information in
the label.

Here is the sample of a label template that displays the value of the point.





To assign the template to the data series set the PointTooltipTemplate
property to the following:


Since it is a standard data template, the complex label can be built, for
example, the next sample template defines the data label for the XY chart
which shows both coordinates of the data point.

It uses the standard grid with two columns and two rows as a container. The
x-value of the point is obtained with indexer of the DataPoint class. The
indexer allows getting the values for the data series classes which support
several data sets, such as XYDataSeries class.

BEGIN CODE
















/>



Path=Value}" />




To assign the template to the data series set the PointTooltipTemplate
property to the following:



END CODE

Hope this helps.

Regards,
Patrick

I am trying to implement your code and I am running into a couple problems.  First a little background.  I have multiple charts with multiple series on them that are all different xy datasets.  My XAML code for one of the charts is simply.

<my:C1Chart Name="c1Chart1" Margin="53,156.5,27,0" Height="300" VerticalAlignment="Top">

           <my:C1ChartLegend DockPanel.Dock="Right" />

</my:C1Chart>

i fill my charts in code behind using

bunch of code....

chart.Data.Children.Add(CreateDataSeries(sim1pts, ds.DataSetName,brushes[k]));

finish up code....

DataSeries CreateDataSeries(IEnumerable<System.Windows.Point> pts, string name, Brush brush)
        {
            return new XYDataSeries()
            {
                XValuesSource = (from pt in pts select pt.X).ToArray<double>(),
                ValuesSource = (from pt in pts select pt.Y).ToArray<double>(),
                Label = name,
                PointTooltipTemplate ="{StaticResource lbl}",
                ToolTip = true,
                ConnectionStroke = brush,
            };
        }

the "PointTooltipTemplate ="{StaticResource lbl}", " is not currently working.  How would I fill that?
