I have a tlineseries which I am assignning a trend function, the lineseries contains gaps to which I am adding nulls with addnull. When I display the lineseries I have it configured so display shows grpah of curve in x,y, then blank gaps for a few samples where there is null data, then curve continues when there is data. The trend seems to include the null values (period is set to 2), I get a trend where there is contiguous data samples, but trend dives to zero when it hits the null data samples. What's the recommened way of dealing with this please?

thabks

Hi Sean,

I think you would like to have a IgnoreNulls property for the trend function similar as for Exp Mov Average function. See the demo at: What's New ?/Welcome/New Features/Functions/Exp.Mov.Average/Ignore Nulls

I've added it to the wish list to be implemented in further releases (TV52013995).
