I have multiple line series in a chart. Chart lines are drawn first and then dots follow the lines. It's annoying and the size of big dots makes large datasets simply useless. Currently I am doing this for each lineseries...
<chartingToolkit:LineSeries
Title="Socket 2"
Name="LineSocket2"
LegendItemStyle ="{StaticResource Le开发者_StackOverflowgendItemStyle}"
IndependentValueBinding="{Binding timestamp}"
DependentValueBinding="{Binding wattage}"
ToolTip="Socket 2">
<chartingToolkit:LineSeries.DataPointStyle>
<Style TargetType="{x:Type chartingToolkit:LineDataPoint}">
<Setter Property="Visibility" Value="Collapsed"/>
</Style>
</chartingToolkit:LineSeries.DataPointStyle>
</chartingToolkit:LineSeries>
But it doesn't do what I want.
How can it be done?
If it helps anyone, the following works for me:
<chartingToolkit:Chart DataContext="1,10 2,20 3,30 4,40" HorizontalAlignment="Stretch" Margin="-1,14,0,0" Name="chart1" Title="Chart Title" VerticalAlignment="Stretch" Width="806" Height="Auto">
<chartingToolkit:LineSeries Name="Series1" DependentValuePath="X" IndependentValuePath="Y" ItemsSource="{Binding}">
<chartingToolkit:LineSeries.DataPointStyle>
<Style TargetType="chartingToolkit:LineDataPoint">
<Setter Property="Opacity" Value="0" />
<Setter Property="Background" Value="Blue" />
</Style>
</chartingToolkit:LineSeries.DataPointStyle>
</chartingToolkit:LineSeries>
</chartingToolkit:Chart>
The charting toolkit is actually a derivative of the Charting in the Silverlight toolkit.
Hence the answer to the question removing-collapsing-datapoints-in-a-lineseries may work for you.
