FSharp.Charting: Library for Data Visualization

NOTE: FSharp.Charting is mostly used on Windows. See the XPlot package for alternative cross-platform charting.

The FSharp.Charting library implements charting suitable for use from F# scripting. Once you load the library as documented in referencing the library document, you can use the members of the Chart type to easily build charts. The following example creates a candlestick chart for a time series and sets the range of the Y axis:

1:	`Chart.Candlestick(priceSeries).WithYAxis(Max = 29.0, Min = 25.0)`

Chart

The library provides a composable API for creating charts. For example, you can use the Chart.Combine function to create a chart consisting of multiple line charts. The following example creates a single area showing sample income, expenses and profit in a single chart:

1: 
2: 
3: 
4:

Chart.Combine(
   [ Chart.Line(expectedIncome,Name="Income")
     Chart.Line(expectedExpenses,Name="Expenses") 
     Chart.Line(computedProfit,Name="Profit") ])

How to get FSharp.Charting

The FsLab template includes both FSharp.Charting and XPlot.
The Windows version of the library is available as FSharp.Charting on NuGet
There is a preliminary Mac/Linux version of the library is available as FSharp.Charting.Gtk on NuGet. See the XPlot package for alternative cross-platform charting.

FSharp.Charting features

Cross-platform 2D charting and support for pseudo-3D charts on .NET.
Many cross-platform chart types: Area, Bar, Bubble, Column, Line, Point and more.
Create charts directly from FSharp.Data such as lists and tuples.
Use either fluent or pipelined chart specifications.
Create updating 'LiveChart' charts from F# or Rx observables.
Can be used in conjunction with the FSharp.Data library.
Many extra chart types (Windows-only): BoxPlot, Candlestick, Doughnut, ErrorBar, FastLine, FastPoint, Funnel, Kagi and more.

Approach, history and future

This library is a successor to FSharpChart. The last version of FSharpChart was version 0.61.

On Windows, FSharp.Charting is implemented using the Data Visualization charting controls available on Windows in .NET 4.x. On OSX, FSharp.Charting is implemented using the OxyPlot.GtkSharp charting library.
