Is there a way to calculate Kernel smoother

[Anonymous]

Hello,

we want to implement a statisical process in our line charts. Therefore we use a smoother (see picture). I have no clue how to calculate such a Kernel smother (e.g. Gaussian kernel smoother) in QlikView. Does anybody have expierence with this topic?

Kind regards

I would probably write an extension and do the calculation there using some JavaScript libs like this:

An extension has the disadvantage that all reporting tools (like NPrinting) don't support html elements.

Thanks anyway

Hi Frank,

there are server-side extensions on the way for Qlik Sense and QlikView 12. With this you can integrate R or other engines to calculate such curves. This should work with NPrinting too. So, probably best to just wait..
