2 mins read

This article describes how to create a Tornado Chart using the Bar and RangeColumn  in WPF Charts.

Tornado Chart is a special type of bar chart where the bars extend from the defined midpoint. Two series are required for a chart to achieve Tornado Chart by the following these steps.

Tornado Chart using the Bar Chart

Step1: Create Bar Series with Binding of  ItemSourceXBindingPath, and YBindingPath properties.

Step2: By using the LabelTemplate in ChartAdornmentInfo class, you can display the model data in data marker as demonstrated in the following code example.

<!--Create Bar Series and bind Models property to ItemsSource-->
    <chart:BarSeries SideBySideSeriesPlacement="False" EnableAnimation="True"  ItemsSource="{Binding Models}" XBindingPath="Year" Interior="LightBlue"  Palette="None" Label=" Export" YBindingPath="Export">
  <chart:ChartAdornmentInfo AdornmentsPosition="Top" ShowLabel="True" 
                    HorizontalAlignment="Center" VerticalAlignment="Center"     FontSize="10">                       
 <chart:BarSeries EnableAnimation="True" ItemsSource="{Binding Models}" 
  XBindingPath="Year"  Interior="LightCoral" YBindingPath="Import" 
  Palette="None"  Label="Import">
                    <chart:ChartAdornmentInfo AdornmentsPosition="Top" ShowLabel="True" 
                          HorizontalAlignment="Center" VerticalAlignment="Center">
                        <!--LabelTemplate to show Positive values in Label of Series-->
                                    <TextBlock FontSize="10"
   Text="{Binding Converter={StaticResource ValueConverter}}"/>

Tornado Chart using the Range Column Chart

Step1: Create RangeColumn series with Binding of  ItemSourceXBindingPath, and YBindingPath properties.

Step2: By using the LabelTemplate in ChartAdornmentInfo class, you can display the model data in data marker as demonstrated in the following code example.

<!--Create RangeColumnSeries and bind Models property to ItemsSource-->
 <chart:RangeColumnSeries SideBySideSeriesPlacement="False"   EnableAnimation="True" ItemsSource="{Binding Models}" 
              XBindingPath="DeptName" Interior="LightBlue" IsTransposed="True"    Palette="None" High="PassStart" Low="Pass">
            <!--To show label using ChartAdornmentInfo-->                                   
                 <chart:ChartAdornmentInfo AdornmentsPosition="Bottom"                     FontSize="10" ShowLabel="True" HorizontalAlignment="Center"      VerticalAlignment="Center">      
      <chart:RangeColumnSeries EnableAnimation="True" ItemsSource="{Binding Models}" 
   IsTransposed="True" XBindingPath="DeptName" Low="PassEnd"                                                                                          
              Interior="LightCoral" High="Pass" Palette="None" >   <!--To show label using ChartAdornmentInfo-->
                    <chart:ChartAdornmentInfo AdornmentsPosition="Top"  
                           ShowLabel="True"  FontSize="10" HorizontalAlignment="Center"
