Force balance analysis for entire movement

Hi,

Ive been doing some force balance analysis(with loadcell measure) for the purpose of figuring force needed to balance mechanism.(its a window opening mechanism)

Basicly im looking for force that is needed/used to open window fully, window is represented by force that it excerts on mechanism.

It works fine but I need solutions for evry position in mechanism movement envelope.

So far I can do this only by doing few force balance analysis and then make a graph manualy by puting spline trough those values.

Is there some way to get graph of this force needed for entire movement envelope?
