SciChart® the market leader in Fast WPF Charts, WPF 3D Charts, and iOS Chart & Android Chart Components
WPF Chart Per-Axis Scrollbars
// 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 the use of the SciChartScrollBar control.
You can define ScrollBar as a part of an Axis or as a sepparate control, and bind to Axis you need.
Tips!
– To set size of resizing grips you can use GripsThickness, GripsLength properties
– GripsThickness allows to set thickness of vertical/horizontal resizing grips.
– GripsLength allows to set length of grips.
– Orientation allows to set orientation of scrollbar. By default it is bound to axis IsHorizontalAxis property (if axis is horizontal – you’ll get horizontal scrollbar and vice versa).
– To learn how to Style the Scrollbar, please see the SciChartScrollbar – per axis ScrollBars API documentation.
