MatPlotLibNet.Wpf 1.21.0

MatPlotLibNet.Wpf

MatPlotLibNet.Wpf is a WPF chart control for MatPlotLibNet. It renders charts natively with SkiaSharp.

Requirements

The package targets net8.0-windows10.0.19041.0, because SkiaSharp.Views.WPF ships no WPF view for a lower Windows platform version. A project on a bare net8.0-windows, net9.0-windows or net10.0-windows has platform version 7.0 and fails to restore with NU1202. Name the version in your own project file:

<TargetFramework>net8.0-windows10.0.19041.0</TargetFramework>

The same works for net9.0- and net10.0-windows10.0.19041.0.

Quick Start

<wpf:MplChartControl Figure="{Binding MyFigure}" IsInteractive="True" />

Live data

For a chart that keeps changing, bind a StreamingFigure to MplStreamingChartControl instead. It listens to the figure and redraws itself when data arrives, so the figure stays the same object for the life of the chart:

<wpf:MplStreamingChartControl StreamingFigure="{Binding LiveChart}" />

Interaction

Set IsInteractive="True" and the chart control handles all 15 interaction modifiers: pan (drag), zoom (scroll), 3D rotation (right-drag), rectangle zoom (Ctrl+drag), brush select (Shift+drag), span select (Alt+drag), legend toggle (click), reset (double-click, Home or Escape), data cursor (click on a point to pin it), the trendline, level and Fibonacci drawing tools, removing a selected drawing (Delete), crosshair (passive) and hover tooltip. Pointer positions are converted with the range and scale the chart is drawn with, on log and symlog axes too.

Clicking a data point raises DataPointClicked with the point's position in the arrays you plotted; on a StateTimelineSeries it is the segment's position in the list you passed, and hovering a segment shows the event and the stretch it covers. A timeline pans and zooms along time only, and stacked timelines that share one time axis (ShareX) move together. The complete window, with a click that seeks and a marker that follows playback, is State timeline in WPF. To move a line while the chart is on screen, such as a playback marker, change its ReferenceLine.Value and call InvalidateVisual() on the control. When you hand the control a different Figure, pan and zoom follow the new one.
