The supposed workflow, as I understand, is to create a bar chart and add error
bars (actually whiskers) later. The whisker can have a constant value, a
relative to Y, and a range. Something like:
with chart range = A2:A4 and error range = B2:B4
What I don't understand is how the statistics (standard deviation, error,
variance...) should be calculated (and if it's really needed). So what's needed
for a MVP?
