How to create a custom pop-up on a bar chart

[#1]

Hi,
I want to change the default pop up label on a bar chart to a custom one.

For example, instead of having :   

customer =  John

value = 500

I want to have a custom pop up as follows:
'Sales for customer John is 500'

I know that we can have custom popup labels, but in the properties of the chart I can't find it.

Thanks

Hi,

Create one more expression and put your label. like

='Sales for Customer '&CustomerField&' is '&Sum(Sales)

and, check the Text as Pop-up in Expression Tab.
