从Visual Basic PowerPacks绘制的线上绘制点？ [英] Draw points on the line drawn from Visual Basic PowerPacks?

问题描述

我从Visual Basic Power Pack中绘制了这些行。一个是水平的，另一个是垂直的（如x轴和y轴）现在我想从datagridview（它有两列x轴和y轴）上添加点。我怎么能在它上面画点？

解决方案

最简单的方法就是按照我想的步骤进行操作



1 ）如果没有固定点数，则添加标签的控制数组。

2）添加两个用于坐标输入的文本框，例如textX，textY

3）添加textchanged事件，输入以下代码

 textX.location =新系统.Drawing.Point（Val（txtX.Text），textX.location.Y）
折叠|复制代码
 textY.location =新的System.Drawing.Point（textX.location.X，Val（txtY.Text））

试试这个并回复。

I have drawn the lines from the Visual Basic Power Pack. One is Horizontal and other is Vertical (like x-axis and y-axis) And now I want to add points on it from datagridview(which have two columns x-axis and y-axis). How can i draw points on it?

解决方案

easiest way is following step as I think

1) Add control array of label if number of dots are not fixed.
2) Add two textbox for co-ordinates entry e.g. textX, textY
3) Add in there textchanged event, enter following code

textX.location = New System.Drawing.Point(Val(txtX.Text) , textX.location.Y)
 Collapse | Copy Code
textY.location = New System.Drawing.Point(textX.location.X,Val(txtY.Text))

try this and reply.
