Plot.Core

Cross-Platform Chart Generation Library for .NET Core.

I couldn't find a chart rendering library to run under .NET Core (specifically for, but not limited to, AWS Lambda), so I created this one.

Usage:

let series =
    { originalPoints = Plot.Core.FakeData.monthlyDataDateTimes
      title          = "Air Passenger Data"
      lineStyle      = 
            { Color     = Rgba32.Orange
              Thickness = 2.f }}
let inflatedSeries = 
    { originalPoints = Plot.Core.FakeData.monthlyDataDateTimes |> Array.map(fun op -> { op with y = op.y + 100. })
      title          = "Inflated Air Passenger Data"
      lineStyle      = 
        { Color      = Rgba32.LightBlue
          Thickness = 2.f }}

let settings = Settings.createLineChartSettings "Air Passenger Data Jan 49 – Dec 60" 1500 500
match [series; inflatedSeries] |> createLineChart settings with
| Some image -> image.Save "AirPassengerData.png"
| None       -> failwith "Something went wrong."

And results look like:

The rendering settings can be customized by updating the Settings record from the code above, before passing to createLineChart. The Settings record has the structure:

open SixLabors.ImageSharp

type LineChartSettings = {
    Title               : string
    Width               : int
    Height              : int
    Font                : SixLabors.Fonts.Font
    GridLineStyle       : LineStyle
    MinorGridLineStyle  : LineStyle
    HorizontalGridLines : int option
    VerticalGridLines   : int option
}
