Hi, all.
How can you compare the current value with the previous value in the chart with 2 dimensions.
In my example(see in attachment), I use above() function (chart #1). But it works only when chart has 1 dimension.
When I add dimension (chart #2) it stop work.
Of course, I can create some expressions (1 expression for each value of second dimension) with Set Analysys (chart #3) but it's not flexible variant.
I want get picture as chart #3, but without using a Set Analysys, i.e. I want get the same result (as shown in chart #3) with ONE expressions.
Somebody have any ideas?
