hello, i have a number of sensors arranged along a length of pipe, i have done frequency distribution graphs for each sensor and they are all fine. However i wanted to do a 3 dimensional graph in which the axis from my 2d graphs are still the x and y axes, but the z axes is the length along the pipe in real time. I was then hoping that excel would interpolate a surface or somethin glike that. Is this at all possible? and am I even making sense?
