Multiple definitions for one Variable.

[#1]

I created some line charts with similar looking but different expressions and different formula. I used several variables to make my charts dynamic. I would like to see whether I can have different definitions for one variable in order to reduce the number of variables and to make the maintenance easier.

Thanks

You can use variables within variables. For example:

vSales2012: sum({<Year={2012}>}Sales)

vSales2013: sum({<Year={2013}>}Sales)

vVariance:   num($(vSales2013)/$(vSales2012) -1,'#.0%')

This way you could redefine vSales2012 or vSales2012 and every variable that uses these variables (like vVariance) will use the new definitions.

You can also pass parameters to variables:

vSales: sum({<Year={$1}>}Sales)

vVariance: $(vSales(2013))/$(vSales(2012)) -1

I am sorry I might not state my questions clearly. Here is my example. I have a variable named vVariance and its formula are different based upon the data type (continuous data vs discrete data). I do not want to use different variable names for different type of variances. How to implement it? Thanks
