SciChart® the market leader in Fast WPF Charts, WPF 3D Charts, iOS Chart, Android Chart and JavaScript Chart Components
WPF Chart Custom Tooltip Templates
// 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 apply custom ControlTemplates and DataTemplates to various Tooltip modifiers within SciChart.
All the tooltip modifiers such as RolloverModifier, TooltipModifier, VerticalSliceModifier and CursorModifier have pre-defined DataTemplates set as attached properties on RenderableSeries.
These can be overridden if you wish to display a custom tooltip on the chart.
