Bar chart how to calculate a percentage

[#1]

All;

       I am in the process of creating a bar chart that shows a total dollar amount for each division and the colour shows the total number of transactions.   I would like to add the percentage of transactions for each division out of the total. Any ideas on how I can do this please?

  I am drilling down to get to this point and so I am not clear on how to generate the total transaction count to be used as the denominator for the percentage calculation

  Thank you in advance

You might want to use this expression:

SUM( dollar) / SUM(TOTAL dollar)

Make sure you have division in your dimension.

Would you be able to share a sample to show what you have?

[Vegar]

You probably want to put something like

sum(amount) /sum(total amount)

in an expression.

Sure - What is the best way to share - some data is private

Yes definitely, what I am not sure about is how to get the total.

what I have is  count(invoice#) to get a  count of the number of invoices per division

  what I am not sure about is where I can get the total count for the denominator?  Should I do this in the load script and create a field called total_sales

  If the count shows  Shoes = 15,  Coats =  20,  socks = 17  so

  Shoes should be 15/52*100  = 28.8%

Coats                  20/52*100 = 38.4%

Socks                  17/52*100 = 32.6%

Thanks

Count(TOTAL invoice#) as an expression should give you 52. So in order to get the percentage, you can use this

Count(invoice#)/Count(TOTAL invoice#)

It should work for u .=sum(amount) /sum(total amount)

Thank you to all that replied , I was able to get what I needed.

  Does anyone also know how to get the  average of all and display on the title?

For example

    We have a bar chart that shows time to close a ticket by ticket classification.

  Class1 = 20 mins,  Class2 = 90 mins, and class3 = 240 mins

  I would like to show on the title the avg close time  (20+90+240)/3 =116.6 mins

Thank you in advance

May be like this:

Avg(Aggr(YourExpression, YourDimension))
