I want to keep the standard data tip format in my column
charts, but the numbers often look weird - even though the raw
numbers add up neatly to eg 3 decimal places, the data tip shows
15! As an example when the total of a column is 49.346, the data
tip shows "Total: 49.346000000000004". How can I stop this? I can't
find an example of how to do my own data tip function that
replicates the standard so I can round the numbers down.
