Customizing Data Points Using DefaultVisualStyle

The different chart series use different visual elements to display their data points - a bar, an ellipse, etc. You can apply a custom style for those elements via the DefaultVisualStyle property. The property accepts a value of type Style which targets the visual element of the corresponding series. There is an additional DefaultVisualStyleSelector property which can be used to apply different style for the different data point visuals in a series. The selector property is of type StyleSelector.

Setting DefaultVisualStyle of BarSeries

• XAML

<telerik:BarSeries> 
    <telerik:BarSeries.DefaultVisualStyle> 
        <Style TargetType="Border"> 
            <Setter Property="Background" Value="#F47748" /> 
        </Style> 
    </telerik:BarSeries.DefaultVisualStyle> 
</telerik:BarSeries> 

Since Q1 2016, all Cartesian series (excluding RangeSeries) are rendering default visuals using the DefaultVisualStyle property. So, you can use it also with line and area series to display their data point visuals which don't exist by default. Note that when using line or area series you will need to set also the size of the visual. Otherwise it won't be displayed.

Setting DefaultVisualStyle of LineSeries

• XAML

<telerik:LineSeries> 
  <telerik:LineSeries.DefaultVisualStyle> 
    <Style TargetType="Path"> 
        <Setter Property="Width" Value="10" /> 
        <Setter Property="Height" Value="10" /> 
        <Setter Property="Fill" Value="#FF5AC3" /> 
    </Style> 
  </telerik:LineSeries.DefaultVisualStyle> 
</telerik:LineSeries> 

When using a Palette the series' default visual will ignore the color defined in the DefaultVisualStyle and it will use the one provided by the palette.

Customizing Data Points Using PointTemplate

All series supported by the RadCartesianChart expose a PointTemplate property. It is of type DataTemplate and gets or sets the template that describes the visual representation of the data points in a series. There is an additiona PointTemplateSelector property which can be used to apply different visuals for the different data points in a series. The selector property is of type DataTemplateSelector.

Using PointTemplate is recommended only when the DefaultVisualStyle cannot be used.

Setting PointTemplate

• XAML

<telerik:PointSeries> 
  <telerik:PointSeries.PointTemplate> 
      <DataTemplate> 
          <Ellipse Height="5" Width="11" Fill="Blue"/> 
      </DataTemplate> 
  </telerik:PointSeries.PointTemplate> 
</telerik:PointSeries>

The CapLength property controls the size of the caps shown at both ends of the error bar. The property works with relative units between 0 and 1.

The MarkerSize property determines the size of the marker. The property works with absolute value, which means that the marker has fixed size. If the MarkerSize is set to null, the marker will resize according to the cap length.
