Hi, I have made an XY graph in Grasshopper like the upper graph in the rhino screendump via below link. The XY values are available in grasshopper via a list and via a curve. I need to get the positive area (m^3) as well as the negative area under the graph. Till now I tried to solve this graphically without succes. Can anybody help how I can do this?
