liner trend line

[joeybird]

hi

I have a line chart which shows sales % per month, for each country

the dimensions are "Calendar Month" and Country

the measure is % sales

I want to add a singular all countries total  % sales liner trend line... I can add a straight reference line, but need a liner one, as the percentage is different for all countries per month

please help

hi

I cant add a sample app sorry

I have tried to add an expression on the trend line / reference line and it comes up as straight, need it to be liner

because I am using a line chart I can only use 2 dimensions and 1 measure

ideally I need to add to measures and two dimensions

please help

Not an actual app , just a sample app with dummy data that replaces your scenario
