Currently i'm not really working with WPF, but a search with google for 'wpf chart control' gives a lot of promising links.
WPF toolkit has the a good set of chart control, You can use LineSeries control for this. http://wpf.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=29117
The free and awesome WPF Dynamic Data Display library comes with a performance counter sample which does this, and which you can customise to your needs.
The Silverlight toolkit will give you all you need to display such a graph, but you won´t be able to get the data from the client itself in silverlight!
