# Calculating Percentages in Lumira

Hi all,

I am trying to add percentage calculations to my visualisations in Lumira without having to manipulate data in excel before hand.

One example of what i am trying to achieve is a leaver analysis with number of leavers by month and this represented as a percentage of total headcount through using a combined column line chart with 2 Y-axis.

Therefore I need to be able to calculate the percentage of leavers on a seperate value. Is this possible? i.e. to create a measure which would be leavers/headcount which would then be attributed across each month.

Any help would be greatly appreciated!

Mike.

You only have to ADD a CALCULATION in the main measure (NUMERO DE OPERACION in this case) :
