如何使XPlot在Linux / Mono上工作？

Question

I have problems using the charting library XPlot for F# on Linux. When I use the "fsharpi"-command to run a standard example script for the candlestick chart, for instance, the script itself runs without any complains but no browser is opened and nothing is shown.

example-script:

#load "../packages/FsLab/FsLab.fsx" 
open XPlot.GoogleCharts

let data =
    [
        "Mon", 20, 28, 38, 45
        "Tue", 31, 38, 55, 66
        "Wed", 50, 55, 77, 80
        "Thu", 77, 77, 66, 50
        "Fri", 68, 66, 22, 15        
    ]

Chart.Candlestick data

If I run it via:

fsharpi "test.fsx"

nothing happens, after some time just another line of the command prompt appears, but also no error occurs. If I run it via:

fsharpi
#load "test.fsx";;

the following output is shown:

I use VS Code and the Ionide-Extension. I installed the FsLab-Package via Fake and generally works well (except for the charting). I created the project via the "new project"-command within VS Code, but I didn't find a way to also run it via a VS Code-command but used the (integrated) console instead. I tried to use NetCore instead of Mono, but didn't find a way to make it work either. The F# Interactive version I use is 4.1, the latest as far as I know.

I hope my question is now specific enough to meet the community guidelines.

Answer 1

As it has been pointed out in the comments you have to pipe the chart to Chart.Show. Thus the following script should work as intended:

#load "../packages/FsLab/FsLab.fsx"
open XPlot.GoogleCharts

let data =
    [
        "Mon", 20, 28, 38, 45
        "Tue", 31, 38, 55, 66
        "Wed", 50, 55, 77, 80
        "Thu", 77, 77, 66, 50
        "Fri", 68, 66, 22, 15        
    ]

Chart.Candlestick data |> Chart.Show
