I'm currently working with historic data for NCNERR and have been trying to make a serial chart that shows statistics based on the different sites that collected data. Unfortunately, when I filter the data set to include all the sites, set category field to year (I only want 2021), set split by field to site (so each bar is a different site), one of the sites keeps getting excluded from the serial chart even though the missing data appears with other serial chart settings. Has anyone run into a similar issue?
