Really it´s not easy to find

But it was too clumsy and unweildy to work with. So I dropped thee whole idea and made it on a popup window and just drawing 10 smallcircles (I had 10 datasets) with X and Y value being from the dataset. Maybe this could be an intermediate solution till you get to use the ewal Function Trend.
