Double plotted column series graph
posted

Hi Team,

I have got a strange requirement from the end user to customize graph in a double plotted way of Column Series.

Where we need to display one report over other where the same report plots two values after user changes.

I have attached the screen shot of the requirement that i am looking for.

Existing functionality:Currently we have reports displayed with their data densities.

New functionality :Double plotted graph with dashed lines(2nd reading) which denotes the increase/decrease on data density values after end user changes.

Any help from your end is highly appreciated.

Existing Xaml Code:

<Grid>
<Grid.RowDefinitions>

<RowDefinition Height="*"></RowDefinition>
</Grid.RowDefinitions>
<StackPanel Grid.Row="0" >
<!--<Border Grid.Row="0" Height="{Binding ElementName=gdReportGraph,Path=Height}"
BorderBrush="Black"
BorderThickness="0.5"
HorizontalAlignment="Stretch"
Margin="20,20,20,20"
VerticalAlignment="Stretch" Visibility="Hidden" ></Border>-->
<Grid Name="gdReportGraph" >

<Grid.Resources>
<ContentControl x:Key="theTooltip" Background="Black">
<StackPanel Orientation="Vertical">
<StackPanel Orientation="Horizontal">
<TextBlock Text="Service: " FontWeight="Bold"/>
<TextBlock Text="{Binding Item.ServiceName}"/>
</StackPanel>
<StackPanel Orientation="Horizontal">
<TextBlock Text="Report: " FontWeight="Bold"/>
<TextBlock Text="{Binding Item.ReportName}"/>
</StackPanel>
<StackPanel Orientation="Horizontal">
<TextBlock Text="Value: " FontWeight="Bold"/>
<TextBlock Text="{Binding Item.DataDensityValue}"/>
</StackPanel>
</StackPanel>
</ContentControl>

</Grid.Resources>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>

</Grid.RowDefinitions>

<ig:XamDataChart x:Name="chart" Height="450" Margin="2,2,2,50" Grid.Row="1" >
<ig:XamDataChart.Axes>
<ig:CategoryXAxis x:Name="xAxis" ItemsSource="{Binding DataContext, RelativeSource={RelativeSource Self}}" Title="Reports" Label="{}{ReportName}" >

</ig:NumericYAxis.TitleSettings>
</ig:NumericYAxis>
</ig:XamDataChart.Axes>
<ig:XamDataChart.Series>

<ig:ColumnSeries ShowDefaultTooltip="True" HorizontalAlignment="Stretch" XAxis="{Binding ElementName=xAxis}" YAxis="{Binding ElementName=yAxis}" ItemsSource="{Binding RelativeSource={RelativeSource Self},Path=DataContext}"

    Hello Sridhar,

    You can achieve this by plotting two column series and setting the Overlap property to 1. That way the second series will be plotted over the first one. You may set the Brush property of the second series to transparent and specify the DashArray to get the desired look and feel.

    I have created a sample for you that demonstrates this (attached).

    Please let me know if you have any other questions or concerns on this matter.

    Best Regards,
