比较时改变标记颜色 [英] Change Marker Color On Comparison

问题描述

您好，

我想仅在比较结果点时更改标记颜色。在我的情况下，Probe1（TextBox值）与Probe1（参考文本框值）进行比较如果它们在绘图标记上不相等则应显示不同的颜色。

I want to change the marker color on comparison of the resultant point only.In my case Probe1 (TextBox value) compares with the Probe1 (Reference textbox value) and if they are not equal on plotting marker should display on different color.

Probe1（0）<> RefProbe1（0）然后系列3的Markercolor应该是RED 

Probe1(0) <> RefProbe1(0) then Markercolor of series 3 should be RED

嘿丹，

感谢回复。这是代码我已经应用

Thanks for the Reply.Here is the code i have applied

 
dim test as integer = Chart1.Series("Series1").Points.AddXY(Val(TextBox1.Text), Val(TextBox2.Text))

If Val(TextBox5.Text) > 21 Then
            Dim i As Integer = CInt(Val(TextBox8.Text))
            For Each pt As DataPoint In Chart1.Series("Series1").Points
                Dim sev As String = TextBox2.Text
                ' this will be your value depending upon which you could set the color
                Select Case sev
                    Case TextBoxList(i).Text
                        Chart1.Series("Series1").Points(test).MarkerColor = Color.Red
                        'Exit Select
                    Case Else
                        Chart1.Series("Series1").Points(test).MarkerColor = Color.Yellow
                        Chart1.Series("Series1").Points(test).MarkerBorderColor = Color.Yellow
                End Select
            Next
