Chart Templates¶

Using premade templates¶

Premade templates can be accessed via the ChartTemplates module. In fact, the ChartTemplates.plotly template is always active by default (see global defaults)

In [3]:

open Plotly.NET

let lightMirrored =
    Chart.Point(xy = [ 1, 2 ]) |> Chart.withTemplate ChartTemplates.lightMirrored

In [ ]:

lightMirrored

Here are the contents of the template plotly which is used by default for all charts: https://github.com/plotly/Plotly.NET/blob/6e28decca64441320d8cffab5bcfee664b118c36/src/Plotly.NET/Templates/ChartTemplates.fs#L163-L665

Creating custom templates¶

Chart Templates consist of a Layout object and a collection of Trace objects. Both are used to set default values for all possible styling options:

In [5]:

open Plotly.NET.TraceObjects

let layoutTemplate =
    Layout.init (Title = Title.init ("I will always be there now!"))

let traceTemplates =
    [ Trace2D.initScatter (
          Trace2DStyle.Scatter(Marker = Marker.init (Symbol = StyleParam.MarkerSymbol.ArrowLeft, Size = 20))
      ) ]

let myTemplate = Template.init (layoutTemplate, traceTemplates)

let myTemplateExampleChart =
    Chart.Point(xy = [ 1, 2 ]) |> Chart.withTemplate myTemplate
