SciChart® the market leader in Fast WPF Charts, WPF 3D Charts, and now iOS Charting & Android Chart Components

// 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.

DOWNLOAD THE SDK

// WPF Chart Legends API

Generates a simple line chart with a chart legend. The Legend is created as follows:

– Adding a LegendModifier Type to the SciChartSurface.ChartModifier. This aggregates and exposes series data which you can bind to.
– Adding a SciChartLegend to the chart, binding it to LegendModifier.LegendData.SeriesInfo.

Tip!

There are many different configurations for the legend, including auto-creation of legend, or fine grained control over the legend rows. Please review the API documentation below carefully for further informatino.
