Scattered point graph issues

[Muhammad]

Hi,
I am using Scattered point chart. Following are issues coming
1) I used different point shape like diamond, square , circle etc. I wanted to increase the size so that then can be visible. But whenever i give point size, the actual shape gets cut and the small piece of every shape is visible. I want to make some series prominent.
2) Tooltip opening event is not firing even i made showtooltp= true as suggested in another form. I am giving itemsource if the series in code behind.
 Following is my code

<telerikChart:RadChart x:Name="radChart" >


            <telerikChart:RadChart.DefaultView>
                <telerikCharting:ChartDefaultView>
                   
                    <telerikCharting:ChartDefaultView.ChartLegend>
                        <telerikCharting:ChartLegend x:Name="chartLegend" Header="Legends" UseAutoGeneratedItems="True"/>
                    </telerikCharting:ChartDefaultView.ChartLegend>
                    <telerikCharting:ChartDefaultView.ChartArea>
                        <telerikCharting:ChartArea LegendName="chartLegend" EnableAnimations="True"  ToolTipOpening="ChartArea_ToolTipOpening">
                            <telerikCharting:ChartArea.AxisX>

Hello Muhammad,

Since there is some problem with our PointSize property in WPF and our developers are after it I can suggest you this work-around to set custom Shape and Size for the Scatter Points:

Retemplate the default Scatter template by setting the wanted Size for the Scatter point like this:

<Style x:Key="Custom" TargetType="telerik:ScatterPoint">
           <Setter Property="Template" >
               <Setter.Value>
                   <ControlTemplate TargetType="telerik:ScatterPoint">
                       <Canvas x:Name="PART_MainContainer">
                           <telerik:PointMark x:Name="PART_PointMark"
                                                  Canvas.Top="{TemplateBinding StartPointY}"
                                                  PointMarkCanvasLeft="{TemplateBinding PointMarkCanvasLeft}"
                                                  PointMarkCanvasTop="{TemplateBinding PointMarkCanvasTop}"
                                                  ShapeStyle="{TemplateBinding PointMarkShapeStyle}"
                                                  Size="20" />
                       </Canvas>
                   </ControlTemplate>
               </Setter.Value>
           </Setter>
       </Style>

Set the template in code-behind like this:

RadChart1.DefaultSeriesDefinition.ItemStyle = this.Resources["Custom"] as Style;

Hello Muhammad,

The sample project attached demonstrates a Scatter Series where those with PointShape=Circle have Tooltip (ShowItemTooltips = true). The ChartArea.ItemToolTipOpening event is used to define the content of the tooltip - in this case the YValue of the Point.
