Question

我在使用Linux上的F＃图表库XPlot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，脚本本身运行时没有任何抱怨，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：

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：

fsharpi
#load "test.fsx";;

显示以下输出：

我使用VS Code和Ionide-Extension。我通过Fake安装了FsLab-Package并且通常运行良好（图表除外）。我通过VS Code中的“new project”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（集成）控制台。我尝试使用NetCore而不是Mono，但也找不到让它工作的方法。我使用的F＃Interactive版本是4.1，据我所知最新版本。

我希望我的问题现在具体到足以满足社区准则。

正如评论中指出的那样，你必须将图表管道输入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

如何让XPlot在Linux / Mono上运行？
