Why do you think that all other graphs than P2 have rounded correctly?
The value looks correct to me since 1,575.6 is a roudned value of 1,575,560,429.9
Are you expecting 429.9 to round up to 430.0?
In that case you need to consider that the underlaying data probabaly contains more decimals so that the real value is for example 429.89999999 meaning the round up is 429.9. Such a microscopic decimal variation can occur when large numbers are calculated since all number are stored as floating point values which are not exact numbers. However, QlikView follows the IEEE Standard on how to store and calculate float values so this is according to specification.

Well the explanation is basically that in Grouped mode the number shown is the value calculated by the chart expression (treated as text not number), whereas for the stacked chart the number is the sum of the values of all the stack segments formatted with the axis setting for number format.
This means that for the Stacked chart the Value shown will be divided by 10e6 as that is the unit of the axis, whereas that will not happen in the grouped one.
This has appeared after we wanted to simplify chart settings by turning "Text on Datapoint"/"Number on Datapoint" into a single setting "Value on Datapoint", using the old "Text" option wherever available.
