I'm struggling with the idl routine VELOVECT. I would like to obtain a squared output of a velocity field in X windows and in postscript. Neither setting: IDL>window,0,xs=400,ys=400 nor IDL>device,filename='myfile.ps',xsize=10,ysize=10 gave an exactly squared plot in X windows or postscript?! Furthermore, does anyone know how to fix the length scale of the vectors. The VELOVECT routine sizes the vectors in relation to the longest vector. This does not allow to compare different vector fields. Any hint would be greatly appreciated, Martin -- :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: ::::::::::::::::: :::::: Martin Kempf :::::::::::::::::::::::::: // // \\ // // // :: :::::: University of New Hampshire ::::::::::: // // // \\// /////// :: :::::: Department of Mechanical Engineering :: /////// // \\ // // :: :::::: Kingsbury Hall 133 ::::::::::::::::::::::::::::::::::::::::::::::::::: :::::: 33 College Road, Durham, NH 03824-3591 (USA) ::::::::::::::::::::::::: :::::: phone: ++1 (603) 862-4509 (office), ++1 (603) 749-5075 (home) :::::::: :::::: FAX: ++1 (603) 862-1865, e-mail: mk1@kepler.unh.edu ::::::::::::::::::
