For time series, changing the desired increment setting produces an off-by-one error. In other words, setting the dialog to One Week produces tick marks every Three Days and settting the it to One Month produces tick marks every One Week.

Note that TChart1.GetDateTimeStep(dtOneDay) returns 0.5. I would have expected it to return 1.0.

Hi Dave,

I cannot reproduce the problem here (with the TeeChart v6.0.0.5) using the following code :

Code: Select all

Private Sub Form_Load()
With TChart1
    .AddSeries scLine
    .Series(0).XValues.DateTime = True
    .Axis.Bottom.Labels.Angle = 90
    .Axis.Bottom.Increment = .GetDateTimeStep(dtOneMonth)
    For i = 37700 To 37725
    .Series(0).AddXY i, Rnd * 100, "", clTeeColor
    Next i
End With
End Sub

Private Sub Command1_Click()
MsgBox TChart1.GetDateTimeStep(dtOneDay)
End Sub

Also, it returns 1 to me.
Which TeeChart Pro version are you using ? Also, if you still having problems, could you please post the code you're using so I can reproduce the problem "as is" here ?

I have found the problem with my C++ code returning the wrong value in the call to GetDateTimeStep(). It seems that TChart has added a new constant to the TeeChartDefines.h file namely dtOneMicrosecond which shifted the other constants by one.

I have e-mailed you a sample project that demonstrates the Teechart properties problem.
