Add range of points dynamically
29 Jul 20211 minute to read
Whenever you add a data point to ItemsSource dynamically, corresponding data will be updated inside chart series synchronously. This operation will be happening for each and every data point that we add subsequently. You can avoid this by calling SuspendSeriesNotification method of Chart before adding range of data points and then call ResumeSeriesNotification to update all the data points that have been added between these two method calls.
Chart.SuspendSeriesNotification(); // ... // Add multiple data points. // ... Chart.ResumeSeriesNotification();
