如何使 XPlot 在 Linux / Mono 上运行?

Question

我在Linux上使用图表库XPlot for F#时遇到问题。例如，当我使用 "fsharpi"-命令为烛台图表运行标准示例脚本时，脚本本身运行没有任何抱怨，但没有打开浏览器，也没有显示任何内容。

示例脚本：

#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

如果我通过以下方式运行它：

fsharpi "test.fsx"

没有任何反应，一段时间后只出现命令提示符的另一行，但也没有发生错误。 如果我通过以下方式运行它：

fsharpi
#load "test.fsx";;

将显示以下输出：

我使用VS Code和Ionide-Extension。我通过 Fake 安装了 FsLab 包，并且通常运行良好(图表除外(。我通过 VS Code 中的"新项目"命令创建了项目，但我没有找到通过 VS Code 命令运行它的方法，而是使用了(集成(控制台。我尝试使用NetCore而不是Mono，但也没有找到使其工作的方法。 我使用的 F# 交互式版本是 4.1，据我所知是最新的。

我希望我的问题现在足够具体，可以满足社区准则。

正如评论中指出的那样，您必须将图表通过管道传输到Chart.Show。因此，以下脚本应按预期工作：

#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
