Left axis titles displayed but all series unchecked

[PascalL]

Hi,
I create line series added in legend with checkbox and title in left axis using custom axes. When all series or few series are selected, the relevant left axis titles are shown as expected i.e. only the titles of the selected series. But when all series are unselected, all the left axis titles are displayed (see the attached screens copy). Could you help me to avoid this?
Many thanks in advance.

Hi Pascal,

You could implement some logic in the OnClickLegend event to hide all the axes when no series is visible. For example, this seems to work fine for me here:

Code: Select all

Private Sub TChart1_OnClickLegend(ByVal Button As TeeChart.EMouseButton, ByVal Shift As TeeChart.EShiftState, ByVal X As Long, ByVal Y As Long)
  Dim showAxes As Boolean
  showAxes = False

  Dim i As Integer
  For i = 0 To TChart1.SeriesCount - 1
    If TChart1.Series(i).Active Then
      showAxes = True
      Exit For
    End If
  Next i
  
  For i = 0 To TChart1.Axis.CustomCount - 1
    TChart1.Axis.Custom(i).Visible = showAxes
  Next i
End Sub

Here it is the rest of the code I used to test the above:

Code: Select all

Private Sub Form_Load()
  TChart1.Aspect.View3D = False
  
  TChart1.Panel.MarginLeft = 7
  TChart1.Legend.CheckBoxes = True

  Dim i, nSeries As Integer
  nSeries = 4
  For i = 0 To nSeries - 1
    TChart1.AddSeries scLine
    TChart1.Series(i).FillSampleValues 5
    TChart1.Series(i).VerticalAxisCustom = TChart1.Axis.AddCustom(False)
    With TChart1.Axis.Custom(i)
      .AxisPen.Color = TChart1.Series(i).Color
      .Title.Caption = "Custom " & Str$(i)
      .Title.Angle = 90
      .Title.Font.Color = TChart1.Series(i).Color
      .PositionUnits = puPixels
      .StartPosition = i * 100 / nSeries
      .EndPosition = (i + 1) * 100 / nSeries
    End With
  Next i
End Sub

Hi Yeray,

Thank you for this nice answer. What about using this event callback with VS C++ ?

FYI, we use some events in the following way:

Code: Select all

BEGIN_EVENTSINK_MAP(CResult, CDialog)
    //{{AFX_EVENTSINK_MAP(CResult)
	ON_EVENT(CResult, IDC_TCHART1, 37 /* OnMarkTipToolGetText */, OnMarkTipToolGetTextTchart1, VTS_I4 VTS_PBSTR)
	ON_EVENT(CResult, IDC_TCHART1, 19 /* OnMouseDown */, OnMouseDownTchart, VTS_I4 VTS_I4 VTS_I4 VTS_I4)
	ON_EVENT(CResult, IDC_TCHART1, 21 /* OnMouseUp */, OnMouseUpTchart, VTS_I4 VTS_I4 VTS_I4 VTS_I4)
	ON_EVENT(CResult, IDC_TCHART1, 201 /* OnMouseEnterSeries */, OnMouseEnterSeriesTchart1, VTS_I4)
	ON_EVENT(CResult, IDC_TCHART1, 202 /* OnMouseLeaveSeries */, OnMouseLeaveSeriesTchart1, VTS_I4)
	ON_EVENT(CResult, IDC_TCHART1, 20 /* OnMouseMove */, OnMouseMoveTchart1, VTS_I4 VTS_I4 VTS_I4)
	//}}AFX_EVENTSINK_MAP
END_EVENTSINK_MAP()

but I can't find where this code comes from.

Hello Pascal,

The easiest way to achieve add Event using VS c++ is adding Event OnClickLegend in design time following next steps:
1.- Open Design time dialog and select the Chart.
2.- Click with right button and choose Events
3.- Select OnClickLegend event and add it.
4.- After do it, event is created automatically and added in the code.

The code should be similar as next:

Code: Select all

Hi Sandra,

Thank you for this nice help. I feel I got all what I need.
Have a great day.
