Chart With Logging - Mouse Over

[DavidSr]

399y Beta 33 Chart with logging.

I have a chart logging two values that is configured to use a line. The values are logged in 15 minute intervals.


When I rest the mouse over the Top line the value at the cursor is displayed. But it does not display a value when resting the mouse anywhere on the bottom line.

It seems that only series(0) ToolTip is set. All other series ToolTip property will have to be set as well.

Hi Godra,, could you expand on that? not sure what I need to resolve it, looked at mainform.vb but don't see any code for it. Am I supposed to be looking for something starting with something like this?

Code: [Select]

// Set ToolTips for Data Point Series ....

chart1.Series[0].ToolTip =

David, my suggestion was more for Archie than you, but here is a temporary fix you could use (inside the Region "Subscribing and PLC data receiving" of the ChartWithLogging control):

Code: [Select]

    Private seriesToolTipCreated As Boolean
    Private Sub PolledDataReturned(ByVal sender As Object, ByVal e As SubscriptionHandlerEventArgs)
        If Not seriesToolTipCreated AndAlso MyBase.Chart1.Series.Count > 0 Then
            For i = 0 To m_PLCAddressValueItems.Count - 1
                MyBase.Chart1.Series(i).ToolTip = "#AXISLABEL, #VALY"
            Next
            seriesToolTipCreated = True
        End If

        If e.PLCComEventArgs.ErrorId = 0 Then
            Try
                If String.IsNullOrEmpty(e.SubscriptionDetail.PropertyNameToSet) Or String.Compare(e.SubscriptionDetail.PropertyNameToSet, e.PLCComEventArgs.PlcAddress, True) = 0 Then
                    PolledDataReturnedValue(sender, e.PLCComEventArgs)
                ElseIf e.SubscriptionDetail.PropertyNameToSet = "Value" Then
                    PolledDataReturnedValue(sender, e.PLCComEventArgs)
                Else
                    Try
                        '* Write the value to the property that came from the end of the PLCAddress... property name
                        Me.GetType().GetProperty(e.SubscriptionDetail.PropertyNameToSet).
                                    SetValue(Me, Utilities.DynamicConverter(e.PLCComEventArgs.Values(0),
                                                Me.GetType().GetProperty(e.SubscriptionDetail.PropertyNameToSet).PropertyType), Nothing)
                    Catch ex As Exception
                        'OnDisplayError("INVALID VALUE RETURNED!" & a.PLCComEventArgs.Values(0))
                    End Try
                End If
            Catch ex As Exception
                DisplayError("INVALID VALUE!" & ex.Message)
            End Try
        Else
            DisplayError("Com Error " & e.PLCComEventArgs.ErrorId & "." & e.PLCComEventArgs.ErrorMessage)
        End If
    End Sub
