Using C# and WPF to Create Fast Plots for Telemetry Analysis on Large Data Sets

Abstract

Upon completion of a test where telemetry(TM) data was collected, the resulting TM file will usually contain millions of data points. Traditionally MatLab™, Mathlab™, or some third party software is used to plot the data. These methods may not always be desirable due to the expense of licensing, restrictions on the ability to create custom graphs and the inability to quickly plot large amounts of data. These problems were solved by using Windows Presentation Foundation (WPF) graphics capabilities in conjunction with C# to develop a unique set of algorithms to display custom graphs of unlimited size with quick response.
