How to make a line chart in wpf RRS feed

  • Question

  • Hi All,

    I am working on a WPF project based on .Net 3.5, there is a line chart in this project as the follow:

    I find WPF Toolkit is a free control for chart in wpf, so I write code as the follow:

    <Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="10" Grid.Column="1" Grid.Row="0">
                <charting:Chart x:Name="waitingtasks" BorderBrush="Transparent" BorderThickness="0" VerticalAlignment="Stretch" Title="Waiting Tasks">
                        <Style TargetType="datavis:Title">
                            <Setter Property="HorizontalAlignment" Value="Left"/>
                            <Setter Property="Foreground" Value="White"/>
                        <Style TargetType="datavis:Legend">
                            <Setter Property="Width" Value="0" />
                        <charting:LinearAxis Orientation="X" Title="Time" Interval="20" ShowGridLines="False"/>
                        <charting:LinearAxis Title="Number of Waiting Tasks" Orientation="Y" Interval="5" ShowGridLines="False"/>
                    <charting:LineSeries DependentValuePath="Value" IndependentValuePath="Key" ItemsSource="{Binding}" IsSelectionEnabled="True" 

    But I get an error:

    Could not load file or assembly 'WPFToolkit, Version=3.5.40128.1, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

    It's very wired. Nothing to do with WPFToolkit assembly. 

    Any idea? or Is there other free controls for chart in wpf?

  • Hi Vic,

    According to your code, I’ve created a sample project on .Net framework 3.5. Everything is ok in my side.

    For your error message, I suggest you add a reference to WPFToolkit.dll (Not just System.Windows.Controls.Input.Toolkit),

    you can download from this:  You can download it from the link below:

    I've uploaded my project to SkyDrive:

  • Hi Franklin,

    Thanks for your reply. I think the reason is that this assembly is dependent on WPFToolkit.dll. I use both of them, but their versions are different. This is wired because i see the version of them are the same in VS. Today I compile those two assemblies by myself, and it works. Thanks again. 

    BTW, Are there another good free controls for line chart in wpf?

  • Hi Franklin,

    Thanks for your help. I select to use OxyPlot(an open source chart control, based on .Net 4 or higher) in my project. I do some changes on OxyPlot to fit my project which bases on .Net 3.5. 

    I mark your reply as the answer.

  • FYI: WPFToolkit.dll is not supported by .NET 4.5.

    I may try OxyPlot.
