Hi
Do this here is the trick
I have created a formula to calculate % and divided by 100
{Financials.Net Sales} % {Financials.Cash}/100
then simply create your chart display data label values in bar
then format data lablel select percent and 2 decimal places
you have the correct figure with % symbol.
you have to divide the original value with 100 as the percent option in format datalabel is dividing the datavalues by 100 do wrong results so basically you are dividing the original values by 100 to get 0.12
and then in chart labels you are showing them as % with 2 decimal places converting to 12%
Cheers
