Looker not displaying prediction interval

Looker Q&A Looker

Hi,

I 'm using forecasting functionality in looker and had prediction interval toggled on. The chart was plotting the interval before, but stopped plotting the interval several days ago. I didn’t make change to the view. Wonder if it’s a bug?

Hi @cyv

Thanks for reaching out!

There can be reasons why a forecase might not be generated - Has the nature of the data changed significantly recently? Try playing around with the Prediction Interval to see if a forcase can be generated and check out the link below for some more troubleshooting suggestions:

Hi Brendan,

Thanks for the reply!

Sus this is a UI bug from looker because, if I hover over the data point, the prediction interval data shows up, so I guess the interval is generated successfully, but just not plotting out by looker for some reason.

Here’s a screenshot where the prediction interval was there first two days after I put up the view.

Another follow up question: is there a way to extract those prediction interval bounds as data columns in looker?

Thanks in advance for your help :blush:
