Hello every body?     Here I have a datafile like following ?     x1 y1 z1     x2 y2 z2     x3 y3 z3       .       .       .     xn yn zn They are not regular points! But some scatter points .Wheng I user StreamLine to link them, The Streamline module cpmplains that it's need regular grids !  Did anyone have a good ideia to link this point together?     Thank in advance!
