This is in Ignition 8.1.2–I don’t have a later version installed yet to confirm whether it applies to them as well.
All of these columns have the same format settings:
The null values in October and November render as blank (great) and the number format is applied with one decimal place as expected. In the December column, the first row has a null value and it renders as null (as well as later nulls in this column) and the number formatting doesn’t get applied to any values in the column. This issues consistently occurs in any column with a null value in the first row (tested with varying datasets).
I’m guessing this could be worked around via a script transform to replace nulls in first row with something else, but haven’t tried yet. Any other suggestions, or is that the way to go?
