from QlikView reference:


Backcast This function operates on trend lines. Enter into the text edit box how far back

you would like to estimate the trend line. The backcast portion of trend lines is displayed as dotted.

Forecast Enter into the text edit box how far you wish to predict the trend line. The forecast portion of trend lines is displayed as dotted.

It's all up to trendline you want to use, but with linear trendline it would be something like in attached document

You want like following:

Hi,

As you told, you like to display predicted data on the chart. So, i thing trendline and forecast will not be good solution in your case. I think you should rather calculate your prediction in load script or in expressions, depending if your prediction algorithm depends less or more on user selections.
