hmmm interesting , now holback is as per the definition
holdbackSyntax: holdback=Description: Specifies the number of data points from the end that are not to be used by the predict command. Use in conjunction with the future_timespan argument. For example, 'holdback=10 future_timespan=10' computes the predicted values for the last 10 values in the data set. You can then judge how accurate the predictions are by checking whether the actual data point values fall into the predicted confidence intervals. Default: 0
So, what I am not getting is if you have a data set of 10K observations AND you holdback the entire 10k as shown here , then what are you basing the prediction upon?
if i modify your query to something like * source="weeklyTrends-growthUnderlying (1).csv" | predict "value" as prediction algorithm=LLP5 holdback=1000 future_timespan=1000 upper95=upper95 lower95=lower95 | forecastviz(10005, 10000, "value", 95)
Does it work?
