We posted previously about the development of the WPF chart controls. With the release of the June WPF Toolkit you now have the controls at your fingertips. You can make bar, pie, bubble, scatter and line graphs. Check out this blog post for details!
Here’s the code for the image above:
Add a reference to the System.Windows.Controls.DataVisualization.Toolkit assembly in your project, add the namespace for the Charting controls, add a chart in XAML and add some data in code behind. Instant pie chart!
XAML
<Window x:Class="WpfChartControl.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:toolkit="http://schemas.microsoft.com/wpf/2008/toolkit"
xmlns:charting="clr-namespace:System.Windows.Controls.DataVisualization.Charting;assembly=System.Windows.Controls.DataVisualization.Toolkit"
Title="Window1" Height="300" Width="300">
<Grid>
<charting:Chart x:Name="chart" Width="350" Height="250">
<charting:Chart.Series>
<charting:PieSeries ItemsSource="{Binding}"
DependentValuePath="Value"
IndependentValuePath="Key"
Title="Pet Preference" IsSelectionEnabled="True" />
</charting:Chart.Series>
</charting:Chart>
</Grid>
</Window>
C#
chart.DataContext = new KeyValuePair<string, int>[] {
new KeyValuePair<string, int>("Dog", 30),
new KeyValuePair<string, int>("Cat", 25),
new KeyValuePair<string, int>("Rat", 5),
new KeyValuePair<string, int>("Hampster", 8),
new KeyValuePair<string, int>("Rabbit", 12) };
VB
chart.DataContext = New KeyValuePair(Of String, Integer)() _
{New KeyValuePair(Of String, Integer)("Dog", 30), _
New KeyValuePair(Of String, Integer)("Cat", 25), _
New KeyValuePair(Of String, Integer)("Rat", 5), _
New KeyValuePair(Of String, Integer)("Hampster", 8), _
New KeyValuePair(Of String, Integer)("Rabbit", 12)}
