How can I create a profiler GUI in WPF?

I am looking to create a task profiler in WPF with an UI similar to the one of incredibuild.

Eg, timed tasks appear as strips on their resp开发者_高级运维ective line. Have a look at:

to see what I mean. I am unsure what the best way to tackle this problem is? Should I override the Panel class creating a custom layout panel for this or might there be an existing control/library out there that can fit my needs. I have so far had a look at various charting controls but am unsure of weither they can be tweaked to achieve this behaviour or not. I am really hoping for someone who has been using WPF for a while to help me narrow down my search. It is not exactly easy to know what to google for either :)

In WPF this kind of chart is absolutely trivial. No special charting package is required:

In your resources, define a DataTemplate for displaying the event whose width is bound to the event length:

  <DataTemplate TargetType="{x:Type local:Event}">
    <Border Width="{Binding EventLength}">  <!-- This sets the width -->
      <Border Margin="1" Padding="1" StrokeThickness="1" Stroke="Black"
              Background="{Binding EventColor}"> <!-- Actual border -->
        <TextBlock Text="{Binding EventDescription}" />
      </Border>
    </Border>
  </DataTemplate>

Also define a horizontal items panel template:

  <ItemsPanelTemplate x:Key="HorizontalPanel"><DockPanel/></ItemsPanelTemplate>

Now your actual chart is trivial to build:

<ItemsControl ItemsSource="{Binding CPUs}">
  <ItemsControl.ItemTemplate>
    <DataTemplate>
      <DockPanel>
        <TextBlock Width="100" Text="{Binding Name}" /> <!-- CPU name -->
        <Rectangle Width="1" Fill="Black" />            <!-- Vertical divider -->
        <ItemsControl ItemsSource="{Binding Events}"    <!-- Events -->
                      ItemsPanel="{StaticResource HorizontalPanel}" />
      </DockPanel>
    </DataTemplate>
  </ItemsControl.Template>
</ItemsControl>

If you have gaps between your events, simply add a "Gap" object to your Events collection to represent them, then add a DataTemplate for gaps:

<DataTemplate TargetType="{x:Type local:Gap}">
  <UIElement Width="{Binding GapWidth}" />
</DataTemplate>
