graphing over time

[Andyandy26]

Hi and I was wondering if there was a way I could have a graph (line graph) that will plot a value over time and where is slowly scrolls as it goes? I have my PLC outputting my voltage at N7:1 and I have spent many days and nights looking for a way. any help would be appreciated.

A trending chart is fairly easy to create. Here are the basic steps:

1) Add a Chart from the Data group in the Toolbox
2) In the Chart properties, go into the series collection by clicking in the property,then clicking the button with the elipsis
3) From the pop up window, change the ChartType to Line
4) Click OK
5) Add a timer from the All Windows Forms group in the ToolBox
6) Set the timer Interval to the sample time you want in milliseconds
7) Set the Enabled property to True
8) Double click the timer in the component tray to go to the Tick event handler
9) Add this code:

Private Sub Timer1_Tick(sender As System.Object, e As System.EventArgs) Handles Timer1.Tick
    Dim Value As Integer
    Try
        Value = EthernetIPforCLXCom1.ReadSynchronous("MyTag", 1)(0)
    Catch ex As Exception
        Exit Sub
    End Try

    '* Add the next point to the chart
    Chart1.Series(0).Points.Add(Value)

    '* Do not let more than 100 point be on the chart
    If Chart1.Series.Count > 100 Then
        Chart1.Series(0).Points.RemoveAt(0)
    End If
End Sub

NOTE: Depending on which driver you use, the driver name will change.
