Adding scrollbars to chart component VC++
Hi Michael,
yes, you can use similar code to the following. It's VB code but I think it can be easily translated to VC++-

Code: Select all
Dim AxisMin, AxisMax
Private Sub Form_Load()
HScroll1.Min = 0
HScroll1.Max = 100
HScroll1.Value = 50
With TChart1
.Aspect.View3D = False
.AddSeries scLine
For i = 0 To 100
.Series(0).AddXY i, Rnd * 100, "", clTeeColor
Next i
.Environment.InternalRepaint
AxisMin = .Axis.Bottom.Minimum
AxisMax = .Axis.Bottom.Maximum
End With
End Sub
Private Sub HScroll1_Scroll()
With TChart1
If HScroll1.Value < 50 Then
.Axis.Bottom.SetMinMax AxisMin - (50 - HScroll1.Value), AxisMax - (50 - HScroll1.Value)
Else
.Axis.Bottom.SetMinMax AxisMin + (HScroll1.Value - 50), AxisMax + (HScroll1.Value - 50)
End If
End With
End Sub
Private Sub TChart1_OnScroll()
With TChart1
If (.Axis.Bottom.Minimum + 50) > HScroll1.Min And (.Axis.Bottom.Maximum - 50) < HScroll1.Max Then
HScroll1.Value = .Axis.Bottom.Minimum + 50
End If
End With
End Sub
