This tutorial guides the reader in building a WPF application that uses a bar chart to display continuously updated data from an external data source. The application pings google.com and plots the ping response time using ScottPlot, and displays data about the monitoring process using XAML layout in WPF. The project utilizes Windows Presentation Foundation (WPF) framework, .NET Core SDK 3.1, Visual Studio 2019 with the .NET desktop development workload, and ScottPlot.WPF library for charting capabilities. The Pinger class is responsible for periodically pinging google.com and saving the returned data, while the MainWindow class updates the plot every second using a DispatcherTimer. The application can be enhanced by storing data in a database or sending notifications via Twilio Programmable SMS.
