At Progression diagrams one can specify, which parameter should be used for the x-axis of the progression diagrams in the Meridional contour and Blading windows (Meanline, Profiles, Edges, 3D cross section).

•abs. meridional length M

•rel. meridional length M/MMax

•abs. radius based meridional length m

•rel. radius based meridional length m/mMax

•abs. radius r

•rel. radius r/rMax

•abs. axial length z

•rel. axial Δz/ΔzMax

•abs. chord length l

•rel. chord length l/lMax

Some constellations may yield undefined x-values due to reference (e.g. rMax, ΔzMax) values. Those constellations will be marked in the diagrams. One should use another option in such a case.
