It was the same issue. I was using the shear matrix: [ 1 tan(phi) ] [ 0 1 ] You favor (and the other PLplot core functions use): [ 1 sin(phi) ] [ 0 cos(phi) ] Anyway, this should be fixed in v7870. > (3) The angle of the numerical labels for the tick marks for the > right-hand > Z axis and the Y axis appear to be twisted from being parallel with > the Z > axis for -dev pscairo but not for -dev psc.
