Hide a dimension or classify an chart by a not used dimension
I'm having a problem with an chart(not table) that have 2 dimensions and an expression, but i want to classify my chart with a not used dimension. Example:
There is a chart with customer and the spent value of each one in the month, but these people have different values of weight calculated by it's influence on the world. So on my chart i want to show only customer and their spent value, but classify it by the ascendent weight of each customer, how can i do this?
