Smoothing "noise" in V8.01

Hi,

We are currently running TeeChart 8.01 for Delphi 2007.

Scenario:

Left axis contains numerical values
Bottom axis contains date values

If data contains following dates/values (i.e.):
5/19/2000 / 1.00
5/3/2009 / 22.00
5/6/2009 / 33.00

And a Smoothing function is applied to this series it appears to create "noise" following the last date. This causes the graph to extend beyond the last value and is "confusing" our users.

Function settings is: Interpolate true, Factor 4.

I have tested this with Interpolate false, which removes the "noise" but changes the dynamic of the graph, hence it's not an option to disable that property.

Is there any way to remove that noise from the graph, causing the function line to end (or begin) exactly at the last (or first) value?

Any help would be greatly appreciated.

Thank you,

Marcin.

Hi Marcin,

Yes, I'm afraid that this is a bug. I've added it to the defect list to be fixed for future releases (TV52014173).

Yeray,

Thank you for the quick reply.
We are looking forwards to seeing this fixed as it is being produced on one of our major graphs which is used frequently.

Thank you,

Marcin.
