使用FSharp。从.fs程序中绘制图表,当显示绘图时,它会阻止程序其余部分的执行。有没有一种方法可以生成非阻塞图表?例:我希望下面两段都显示在不同的窗口中,并让程序的其余部分执行。
Chart.Line(Series1) |> Chart.Show // Chart 1
// do some work
Chart.Line(Series2) |> Chart.Show // display this in a second window
// continue executing the rest while the above windows are still open.
您能提供更多关于如何调用Chart.Line
的细节吗?例如,在REPL中,通过FSLab,在winforms中,在wpf?
在fsx文件中工作时,以下内容不会阻止我。另一种方法是将其封装在异步块中,这在执行长时间运行的计算或访问数据库时非常有用。
#load @"....FSLABpackagesFsLabFsLab.fsx"

let rnd = System.Random()
let xs = List.init 100 (fun _ -> rnd.NextDouble() - 0.5)
let xs' = List.init 100 (fun _ -> rnd.NextDouble() - 0.5)
Chart.Line(xs) // |> Chart.Show
Chart.Line(xs') //|> Chart.Show
添加:
async {Chart.Line(xs) |> Chart.Show } |> Async.Start
async {Chart.Line(xs') |> Chart.Show } |> Async.Start
