Let the parameter of value prompt be ?Par1? and the choices as Revenue, Cost.
Now u write the expression of the calculated item in the report page as follows, "If ?Par1?=Revenue then Revenue else Cost.
Here Revenue,Cost should b dragged from the Model Items. So now the calculated item column displays the value of the one selected in the prompt.
Now make a graph using the list report,then place the calculated item on the axis of the chart ,which u wanted to display dynamically based on ur selection.
So now if u select Revenue in the prompt then the grph will take the values for Revenue.And if u select Cost then graph will be with the values of Cost.
