I'm currently having trouble trying to set up a X Y plot using Engine speed, MAP, and wideband. When I open the properties to select engine speed for the X axis, I click on the parameter button, select Engine speed and click OK. After I click OK, Engine speed does not come up in the X axis box. I think the reason for this is because during the parameter selection, the little parameter icon with the sign wave line through that's next to Engine speed it isn't green, it's white for some reason. It seems as though it's not selectable, and I'm not sure why. I tried to read through the help file and couldn't find anything on this. I hope I was clear enough. Thanks!
