Smoothing function

Markus · Post by **Markus** » Wed Jan 12, 2005 5:40 pm

I am using your smoothing function which in general does a good job. But now i am using it with DateTime x-values and there is a funny effect.

It seems to be a precision problem.

When the DateTime values are incremented by higher steps (for instance days) everything works fine, but when the DateTime values (x-values) are only seconds away from each other the smoothing function become confused.

When i transform all the data lets say to the year 1900 it works a little bit longer but as soon as i derease the increments between the single datapoints you will get the same problems.

You can produce similar effects without using the DateTime datatype. You only have to use very high x-values with very low increments between the different x-valuse. Thats why I guess it is a precision problem.

I hope you can reproduce this effect, Markus.

I have downloaded the newest version now, and sadly this bug has not been corrected.

Do you have any idea, when we can expect a bugfix for this point?

Thanks for your assistance.

Markus

Hi Markus,

The new release will be TeeChar for .NET v2 and it will be released before the end of this quarter but I can't tell you if the bug you reported will be included as it hasn't been fixed yet.
