Wrong title extracted from chart

[Vic-M]

#!/usr/bin/env fsharpi --exec

#r "nuget: Plotly.NET"

open Plotly.NET

let chart = Chart.Point(xy = [ 1, 2; 3, 4 ]) |> Chart.withTitle "Test"
let title = GenericChart.getLayout chart

printfn "%A" <| title.TryGetValue "title"

Expected:

Test

Result:

Some Plotly.NET.Title

Hey @Vic-M,
the Chart.withTitle function is a convenience function that does the initialization of a Title object internally, and sets it on the chart. Titles in plotly are objects that can contain more properties than the text, e.g. the font or padding, see here.

So you get what is expected, a title object which contains "Test" on the text property:

open Plotly.NET

let chart = Chart.Point(xy = [ 1, 2; 3, 4 ]) |> Chart.withTitle "Test"
chart
|> GenericChart.getLayout
|> fun l -> l.TryGetTypedValue<Title> "title"
|> Option.get
|> fun l -> l?text
