Hello Everyone, I am new to Jaspersoft Studio and I am trying to pass the last standar devaition value to a chart to simulate LIL UIL bands which are basically CL Target +/- 1* STD devaition. The Variable at the Accumulator is showing me a value of 0.0369 but on the chart is in the group footer band but shows me the all the values from 0 to 0.0369. I am only interested in the last value. This is the graph I get with the increasing Standard devaition (black series) While below is the graph which I would like to see when calcu;ating CL +/- 1*STD Deviation of 0.0369 Any Pointers of how to pass the last value of the std deviation variable to resolve this would be greatly appreciated Thanks Carlos
