As far as I have seen the analysis period doesn’t work when the first hour is bigger than the second, it flips them.
Probably I do it quite complex, but it has worked for me. Delete the analysis period and then create a subset list with the period you are interested in of the data that the adaptive chart asks for (only the numbers, do not add the strings)
Probably someone else will tell you an easier way.
You definitely deserve the title of “power user” after this and your last post (both for GH and LB+HB). You are right that we currently provide no method to get this blind hour. However, quite amazingly, I just removed the checks on the analysisPeriod component and it seems that this ability has been in the back end all along and Mostapha must have forgotten to remove the check for this after adding the capability years ago:
All of the analysisPeriod components are using the same underlying function to slice the data so all of them should work in the same way that the attached test does. I also checked the 3D chart, the sky matrix selector, and a few other components that accept the sliced data and everything is good. I can’t believe how long this unnecessary check must have been in there as the analysisPeriod functions have not been touched in years. I have amended the code here:
