TeeChart Pro Cursor

Hi Team,
I've got a question regarding the cursor Tool:
Is it possible to snap between x-values and get the y-value of every series in the chart?
For example:
- there are 3 line-series in the Chart and you add 1 cursor
- these 3 line-series got the same X-values but different Y-values
- now you want to jump along the X-values and mark the assigned Y-value of each line-series
- so with 3 line-series we would have 1 cursor and 3 marks on it
Thank you in advance!
Best regards,
Florian

Hello,
first, many apologies for the lateness of this reply.
To answer your question: yes, I think this should be possible, and I attach a code example which does most of what you ask.
Code: Select all
Line _line1 = new Line(), _line2 = new Line(), _line3 = new Line();
CursorTool _cursorTool = new CursorTool();
private void InitializeChart()
{
void _cursorTool_SnapChange(object sender, CursorChangeEventArgs e)
{
if(e.SnapPoint > -1)
{
var values = "Line1 YValue: " + _line1.YValues[e.SnapPoint] + Environment.NewLine;
values += "Line2 YValue: " + _line2.YValues[e.SnapPoint] + Environment.NewLine;
values += "Line3 YValue: " + _line3.YValues[e.SnapPoint] + Environment.NewLine;
tChart1.Header.Text = values;
}
}
tChart1.Series.Add(_line1).FillSampleValues();
tChart1.Series.Add(_line2).FillSampleValues();
tChart1.Series.Add(_line3).FillSampleValues();
tChart1.Tools.Add(_cursorTool);
_cursorTool.Series = _line1;
_cursorTool.Style = CursorToolStyles.Vertical;
_cursorTool.Snap = true;
_cursorTool.SnapChange += _cursorTool_SnapChange;
_cursorTool.FollowMouse = true;
}

Hi Christopher,
thank you for your help, but is it maybe possible to post the code in VB.NET again?
Thanks a lot!

Of course, here you are:
Code: Select all
Private _line1 As Line = New Line(), _line2 As Line = New Line(), _line3 As Line = New Line()
Private _cursorTool As CursorTool = New CursorTool()
Private Sub InitializeChart()
TChart1.Series.Add(_line1).FillSampleValues()
TChart1.Series.Add(_line2).FillSampleValues()
TChart1.Series.Add(_line3).FillSampleValues()
TChart1.Tools.Add(_cursorTool)
_cursorTool.Series = _line1
_cursorTool.Style = CursorToolStyles.Vertical
_cursorTool.Snap = True
AddHandler _cursorTool.SnapChange, AddressOf _cursorTool_SnapChange
_cursorTool.FollowMouse = True
End Sub
Private Sub _cursorTool_SnapChange(ByVal sender As Object, ByVal e As CursorChangeEventArgs)
If e.SnapPoint > -1 Then
Dim values = "Line1 YValue: " & _line1.YValues(e.SnapPoint).ToString() + Environment.NewLine
values += "Line2 YValue: " & _line2.YValues(e.SnapPoint).ToString() + Environment.NewLine
values += "Line3 YValue: " & _line3.YValues(e.SnapPoint).ToString() + Environment.NewLine
TChart1.Header.Text = values
End If
End Sub
