holt-winters confidence bands - in the future?

Asked by Charlie Schluting ☃ on 2012-10-16

Hi,

I'd like to view extrapolated data from holt-winters forecasts for now() + 1 day, for example.

I don't want to store future data in whisper (as some previous questions have asked), I just want the graph to render predictions beyond the current data set - in fact, this is what I _expected_ holtWintersForecast() to do.

I don't see that this is currently possible - or am I missing something? :)

Rendering into the future isn't supported still, but the current holtwinters implementation is useful for confidence banding expected values. A common use case would be to make a "glance" dashboard where you can quickly see if the line for today's data is staying within the predicted bands based on yesterday's data; or if your current day is trending towards the limit of your predicted confidence.

Thanks Dave Rawks, that solved my question.
