No, color band tools can also be assigned custom axes, i.e.:Am I correct in that the color band tool can not be used on a custom axis?
Code: Select all
With TChart1.Tools.Items(0).asColorband
.Axis = TChart1.Axis.Custom(0)
.StartValue = 100
.EndValue = 200
End WithI'm not sure of what are you exactly trying to get, can you please be more specific on what a "partial colorband up" consists? Do you mean a colorband not covering the full axis range?Also, can I put only a partial colorband up? or am I going to have to draw it using on after draw?
Yes. If attached to a vertical axis, have it only show up between x and x'. By default, I think the colour band will span the entire x axis, between y and y'. Is that correct?Do you mean a colorband not covering the full axis range?
Code: Select all
Dim Go As Boolean
Private Sub Form_Load()
For i = 0 To 100
TChart1.Series(0).Add Rnd * 100, "", clTeeColor
Next
TChart1.Tools.Items(0).asRectangle.Shape.Transparency = 50
Go = True
TChart1.Environment.InternalRepaint
End Sub
Private Sub TChart1_OnAfterDraw()
If Go Then
With TChart1.Tools.Items(0).asRectangle
.Left = TChart1.Axis.Left.Position
.Top = TChart1.Series(0).CalcYPosValue(50)
.Height = TChart1.Series(0).CalcYPosValue(20) - .Top
.Width = TChart1.Series(0).CalcXPosValue(40) - .Left
End With
Go = False
End If
End Sub
Private Sub TChart1_OnRectangleToolDragging()
TChart1.Tools.Items(0).asRectangle.Left = TChart1.Axis.Left.Position
End Sub
Private Sub TChart1_OnRectangleToolResizing()
TChart1.Tools.Items(0).asRectangle.Left = TChart1.Axis.Left.Position
End SubUh, how is this done in MFC/C++?No, color band tools can also be assigned custom axes, i.e.:Code: Select all
With TChart1.Tools.Items(0).asColorband .Axis = TChart1.Axis.Custom(0) .StartValue = 100 .EndValue = 200 End With
Code: Select all
CAxis& axis = tchart.GetAxis().GetCustom(m_AxisIds[index]);
CToolList & tools = tchart.GetTools();
CColorBandTool & colourBand = tools.GetItems(m_ColourBand).GetAsColorband();
COleVariant iDispatch;
iDispatch.vt = VT_DISPATCH;
iDispatch.pdispVal = axis.m_lpDispatch;
colourBand.SetAxis(iDispatch.Detach());
There is no rectangle tool. I'm using TChart 7.0.0.3. And due to the tight schedule we have, I am not authorised to upgrade to the new version.This is not possible with a color band. However, you can achieve that using a rectangle tool and doing something like this:
However, for reference, what compatibility issues are there if I were to upgrade to 7.0.0.8, and would I just do the Project->Add To Project->Components and Controls->TeeChart Pro Activex control v7 on the newly installed TChart to update the wrappers? Also, what other issues should I be aware of. What sort of testing regime do you do?
Yeah, I saw that one, but I cannot easily use a CRectangle if that wrapper class does not exist. Would you be able to pass me the missing wrapper classes to me?Yes, you are right, rectangle tool wasn't defined. However we have recently fixed this as you can read in this message. Here you'll find the instructions to solve this and some code on how to use TeeChart tools in VC++ applications.
)Code: Select all
CTChart& tchart = GetTChart();
CToolList & tools = tchart.GetTools();
CAxis & axis = tchart.GetAxis().GetCustom(m_AxisIds[index]);
m_ColourBand = tools.Add(tcColorband);
CColorBandTool & colourBand = tools.GetItems(m_ColourBand).GetAsColorband();
VARIANT iAxis;
iAxis.vt = VT_DISPATCH;
iAxis.pdispVal = axis;
colourBand.SetAxis(iAxis);
Any ideas?Additionally, if I use tchart.GetTools().Add(tcRectangle) a First-chance exception is thrown (0xe06d7363). So I do not think this is going to work anyway.
No, as I said before:Could you finally solve this issue using the files I sent?
However, I was able to get the handle to the Device Context and was able to implement my own semi-transparent rectangle.Additionally, if I use tchart.GetTools().Add(tcRectangle) a First-chance exception is thrown (0xe06d7363). So I do not think this is going to work anyway.
