我试图创建一个图表在winforms中,数据绑定到内存中的列表,并获取动态更新列表更改。这里是我的代码:F#Winforms图表异步更新
open System
open System.Linq
open System.Collections
open System.Collections.Generic
open System.Drawing
open System.Windows.Forms
open System.Windows.Forms.DataVisualization
open System.Windows.Forms.DataVisualization.Charting
let link = new LinkedList<double>()
let rnd = new System.Random()
for i in 1 .. 10 do link.AddFirst(rnd.NextDouble()) |> ignore
let series = new Series()
let chart = new System.Windows.Forms.DataVisualization.Charting.Chart(Dock = DockStyle.Fill, Palette = ChartColorPalette.Pastel)
series.Points.DataBindY(link)
let form = new Form(Visible = true, Width = 700, Height = 500)
form.Controls.Add(chart)
let formloop = async {
while not chart.IsDisposed do
link.AddFirst((new System.Random()).NextDouble()) |> ignore
link.RemoveLast()
}
do
Async.StartImmediate(formloop)
Application.Run(form)
Console.WriteLine("Done")
Console.ReadLine() |> ignore
异步似乎工作,但图表从不显示任何东西。它只是显示一个空白窗口。我究竟做错了什么?
