F＃使用Winforms DataVisualization制作条形图 [英] F# Make Bar Chart with Winforms DataVisualization
问题描述
我想用Winforms和F＃制作条形图。我已经看到许多其他C＃示例使用 System.Windows.Forms.DataVisualization.Charting 制作图表，尽管当我尝试打开该库时会说未定义名称空间。
I want to make a bar Chart with Winforms and F#. I have seen many other C# examples making a chart with System.Windows.Forms.DataVisualization.Charting although when i try to open that library then it says then namespace is not defined.
像这样的 let chart = new Chart（）这样简单的操作由于库没有被定义我接受它。尽管我已经看到人们在C＃中执行此操作。 F＃的正确方法是什么？
Something as simple as this let chart = new Chart() doesn't work due to the namespace of the library not being defined i take it. Though I have seen people do this in C#. What is the correct way for F#?
有人能这么热情地向我展示如何在F＃中制作图表并指向条形图的正确方向吗？
Can someone be so kind to show me how to make a chart in F# and point me in the right direction of a bar Chart?
推荐答案
您将需要引用正确的程序集，然后可以打开像这样的命名空间（相当于C＃使用）：
You will need to reference the correct assembly then you can open the namespace (equivalent of C# using) like this:
open System.Windows.Forms.DataVisualization.Charting
但是，在您遵循这条路线之前，我强烈建议您使用 FSharp.Charting ，它是包装器 DataVisualization.Charting ，并且更容易在F＃中使用。
However, before you go down this route, I would strongly recommend you use FSharp.Charting, which is a wrapper arround DataVisualization.Charting and much easier to work with in F#.
这是使用 DataVisualization.Charting
