Hi:

I'm successfully using the rotate and magnifying tools. Now I want to a "move" tool, similar to what the TeeCommander does, but don't want to use the commander per se.

Can I use this tool outside of the commander? Or is this function only available in the commander?

Thanks,

Matt

Hi Matt,

I'm afraid there's no tool to move the chart. Otherwise, you always can emulate this TeeCommander function by doing something similar than following:

Code: Select all

Dim MoveChart As Boolean
Dim StartX, StartY As Double

Private Sub Form_Load()
  TChart1.AddSeries scPoint
  TChart1.Series(0).FillSampleValues 25
  
  MoveChart = False
  TChart1.Zoom.Enable = False
End Sub

Private Sub TChart1_OnMouseDown(ByVal Button As TeeChart.EMouseButton, ByVal Shift As TeeChart.EShiftState, ByVal X As Long, ByVal Y As Long)
  If Button = mbLeft Then
    StartX = X
    StartY = Y
    MoveChart = True
  End If
End Sub

Private Sub TChart1_OnMouseMove(ByVal Shift As TeeChart.EShiftState, ByVal X As Long, ByVal Y As Long)
  If MoveChart = True Then
    With TChart1
        .Aspect.HorizOffset = X - StartX
        .Aspect.VertOffset = Y - StartY
    End With
  End If
End Sub

Private Sub TChart1_OnMouseUp(ByVal Button As TeeChart.EMouseButton, ByVal Shift As TeeChart.EShiftState, ByVal X As Long, ByVal Y As Long)
  If Button = mbLeft Then
    With TChart1
        .Aspect.HorizOffset = X - StartX
        .Aspect.VertOffset = Y - StartY
    End With
    MoveChart = False
  End If
End Sub

Hi:

That's fine, as long as it works. Thanks!

What about the 3d depth tool? Do use the same event structure and follow a "mode" selector to change the 3d-ness? If so, just let me know what the correct method is.

Thanks again,

Matt

Hi Matt,

Here you have an example of how you could achieve similar results as teecommander, using simple buttons:

Code: Select all

Dim RotateChart, MoveChart, ZoomChart, DChart, Go As Boolean
Dim StartX, StartY As Double
Dim StartZoom As Integer

Private Sub Rotate_Click()
  RotateChart = True
  MoveChart = False
  ZoomChart = False
  DChart = False
End Sub

Private Sub Reset_Click()
  With TChart1
    .Aspect.Orthogonal = True
    .Aspect.HorizOffset = 0
    .Aspect.VertOffset = 0
    .Aspect.Zoom = 100
    .Aspect.Chart3DPercent = 15
  End With

  MoveChart = False
  RotateChart = False
  ZoomChart = False
  DChart = False
  Go = False
End Sub

Private Sub Move_Click()
  MoveChart = True
  RotateChart = False
  ZoomChart = False
  DChart = False
End Sub

Private Sub Zoom_Click()
  ZoomChart = True
  MoveChart = False
  Rotate = False
  DChart = False
End Sub

Private Sub ThreeDPercent_Click()
  DChart = True
  ZoomChart = False
  MoveChart = False
  Rotate = False
End Sub

Private Sub Editor_Click()
  TChart1.ShowEditor
End Sub

Private Sub Form_Load()
  With TChart1
    .AddSeries scLine
    .Series(0).FillSampleValues 20
    .Zoom.Enable = False
    .Scroll.Enable = pmNone
  End With
End Sub

Private Sub TChart1_OnMouseDown(ByVal Button As TeeChart.EMouseButton, ByVal Shift As TeeChart.EShiftState, ByVal X As Long, ByVal Y As Long)
  If RotateChart = True Then
    Go = True
    StartX = X
    StartY = Y
  End If
  If MoveChart = True Then
    Go = True
    StartX = X
    StartY = Y
  End If
  If ZoomChart = True Then
    Go = True
    StartZoom = TChart1.Aspect.Zoom
    StartY = Y
  End If
  If DChart = True Then
    Go = True
    StartX = X
    StartY = Y
  End If
End Sub

Private Sub TChart1_OnMouseMove(ByVal Shift As TeeChart.EShiftState, ByVal X As Long, ByVal Y As Long)
  If RotateChart = True And Go = True Then
    With TChart1
      .Aspect.Orthogonal = False
      .Aspect.Elevation = X - StartX
      .Aspect.Rotation = Y - StartY
    End With
  End If
  If MoveChart = True And Go = True Then
    With TChart1
      .Aspect.HorizOffset = X - StartX
      .Aspect.VertOffset = Y - StartY
    End With
  End If
  If ZoomChart = True And Go = True Then
    With TChart1
      .Aspect.Zoom = StartZoom + StartY - Y
    End With
  End If
  If DChart = True And Go = True Then
    With TChart1
      If (X - StartX) < 101 And (X - StartX) > 0 Then
        .Aspect.Chart3DPercent = X - StartX
      Else
        If (X - StartX) > 101 Then
          .Aspect.Chart3DPercent = 100
        Else
          .Aspect.Chart3DPercent = 1
        End If
      End If
    End With
  End If
End Sub

Private Sub TChart1_OnMouseUp(ByVal Button As TeeChart.EMouseButton, ByVal Shift As TeeChart.EShiftState, ByVal X As Long, ByVal Y As Long)
  If RotateChart = True Then
    With TChart1
      .Aspect.Orthogonal = False
      .Aspect.Elevation = X - StartX
      .Aspect.Rotation = Y - StartY
    End With
    Go = False
  End If
  If MoveChart = True Then
    With TChart1
      .Aspect.HorizOffset = X - StartX
      .Aspect.VertOffset = Y - StartY
    End With
    Go = False
  End If
  If ZoomChart = True Then
    With TChart1
      .Aspect.Zoom = StartZoom + StartY - Y
    End With
    Go = False
  End If
  If DChart = True Then
    With TChart1
      If (X - StartX) < 101 And (X - StartX) > 0 Then
        .Aspect.Chart3DPercent = X - StartX
      Else
        If (X - StartX) > 101 Then
          .Aspect.Chart3DPercent = 100
        Else
          .Aspect.Chart3DPercent = 1
        End If
      End If
    End With
    Go = False
  End If
End Sub

Hi:

This code is working fairly nicely (with a few minor mods). Thanks again.

I need to turn off the default left-click mouse behavior that drags and grid around independently of the plotting data, since in some cases, it interferes with the functions in the code you provided. How is that done?

Thanks,

Matt

Hi Matt,

You can use this:

Code: Select all

    TChart1.Scroll.Enable = pmNone

Thanks!

Hi:

Your suggestion doesn't appear to work. Maybe I didn't explain what has happening. This issue occurs when I lasso a box somewhere in the graph. When I let the right button up, the chart appears to zoom in on a particular section. It is this behavior I want to suppress.

Thanks,

Matt

Hi Matt,

Sorry for the confusion. In that case you can try using this:

Code: Select all

    TChart1.Zoom.Enable = False

Thanks! That did the trick.
