Generating a performance-monitoring graph

In the Reporting on performance data recipe, you saw how you could take the data logged by a PLA data collector set and create a performance report. The report in that recipe showed CPU utilization of SRV1. That output is in the form of a table and is a summary of the performance of the server.

Another way to view the performance data is in the form of a graph. PowerShell does not have direct cmdlet support for displaying rich graphs, but the .NET Framework's System.Windows.Forms.DataVisualization namespace does.

This recipe uses the data visualization's Chart object to create a chart and save it as a Portable Network Graphic (PNG) file. You then display the graphic on your workstation.
