WPF Gantt Chart
// WPF Chart Examples
SciChart WPF ships with hundreds of WPF Chart Examples which you can browse, play with, view the source-code and even export each WPF Chart Example to a stand-alone Visual Studio solution. All of this is possible with the new and improved SciChart WPF Examples Suite, which ships as part of the SciChart WPF SDK.
Demonstrates how to use FastStripeRenderableSeries FastStripeRenderableSeries to compose a Gantt Chart.
The FastStripeRenderableSeries requires an StripeDataSeries.
The DiscontinuousDateTimeAxis on the top shows the timeline and excludes weekends using the Calendar with time ranges to skip.
The left panel lists project activities with information about task, department and percentage of completion.
The VerticalLineAnnotation shows the end date of the project. The VerticalSliceModifier shows the current date and it can be used to overview the progress of the project.
