There is a known bug that was found in some version of
Qlikview (example version11.20SR3). In 11.20SR3, % on Pie chart is not
displayed. This was corrected from QlikView desktop v 11.20SR4. If you are
using such version you will need to update to latest version ex 11.20SR5 to be
able to view % in Pie chart.
1. To get the percentages instead of actual values, check 'Relative' on the Expression tab in the properties.
2. To get the percentages to show up on the graph, check 'Values on Data Points' on the Expression tab in the properties.
Hope that helps!
On the expressions tab, select the expression.
In the mid-middle of the tab,right above "display options", you will find "Relative". This will turn the results of the expression into a percentage of the total of the expression. This will automatically turn the number formatting into showing the result as a percentage and all answers will total to 100%.
