Summary:	Change in XValues or YValues does not update Minimum and Maximum

Description Dave Stevens 2014-03-06 20:41:03 EST

I have a Series(0) that is populated with XValues in the range 0 to 1. At runtime, I have a scale function that iteratively applies a factor (say 10) to each XValue which would adjust the range from 0 to 10.

Example Code:

Dim tValues As Steema.TeeChart.Styles.ValueList
tValues = tcDiag.Series(0).XValues
for i = 0 to 100
   tValues.Value(i) = tValues.Value(i) * 10
next i

Looking at tValues in Watch, I can see the Values changing as I step through the code, and even FirstValue changes, but Minimum and Maximum do not change at all.

I have tried tcDiag.Series(0).RefreshSeries() and a few other commands, but none of them work. I have tried with tcDiag.Axes.Bottom.Automatic = True.

tcDiag.AutoRepaint() is set to False because I don't want to see all of the points moving one by one.

Is this a bug? Or am I missing something?

Results confirmed as inconsistent either as tValues.Value(i) or tValues(i) (where tValues is one of the Series' Valuelists.

TeeChart Refresh() method gives different results on Axis repaint depending on approach used. Might be Series' stat refresh call issue.
