It sounds like you are talking enclosure shop, I don't like it for box modeling as much as LspCAD. Having said that, all LinearX graph fuctions are the same across all products for the most part. All the options you want are in the "calculations" button. Many of the display properties are right click on SPL graph and go to "graph parameters". I am writing this off memory as I don't have Leap at home. My button names could be slightly off.
