Intraday Candle Charts

Hi! This is my first post, and I want to thank for your great soft.
How could be to discard in an intraday graph (bottom axis interval with one minute) the frame time where there is no data?
Market opens 08:00 to 22:00, from 22:00 to 08:00 is closed. If I load two consecutive days, the frame time closed appears in the chart with no data.(I want to implement with other intervals, from minutes to hours.)
Thanks in advance.

Hi JuanLu,
The axis don't allow gaps so to achieve that we have to think in another solution.
For example you could use different series for the different days. Doing this way, you will be able to use an horizontal axis for each series (day) and then you could show all them one after the other. Here is an example in vb6:
Code: Select all
Private Sub Form_Load()
TeeCommander1.Chart = TChart1
TChart1.AddSeries scFastLine
TChart1.AddSeries scFastLine
TChart1.Aspect.View3D = False
TChart1.Legend.Visible = False
Dim Values(0 To 1679) As Double
Values(0) = Rnd * 1000 + 1000
Dim i As Integer
For i = 1 To 1679
Values(i) = Values(i - 1) + Rnd * 10 - 5
Next i
Dim StartTime As Date
StartTime = DateAdd("h", 8, DateValue("01/01/2009"))
For i = 0 To 839
TChart1.Series(0).AddXY DateAdd("n", i, StartTime), Values(i), "", clTeeColor
Next i
StartTime = DateAdd("h", 8, DateValue("01/02/2009"))
For i = 0 To 839
TChart1.Series(1).AddXY DateAdd("n", i, StartTime), Values(i + 840), "", clTeeColor
Next i
TChart1.Series(1).HorizontalAxisCustom = TChart1.Axis.AddCustom(True)
TChart1.Axis.Bottom.EndPosition = 50
TChart1.Axis.Custom(0).StartPosition = 50
TChart1.Tools.Add tcColorLine
TChart1.Tools.Items(0).asColorLine.Axis = TChart1.Axis.Bottom
TChart1.Tools.Items(0).asColorLine.Style = clMaximum
TChart1.Series(0).XValues.DateTime = True
TChart1.Series(1).XValues.DateTime = True
End Sub
