    Parametric Plotting Problem

    MarkMcMullan Copper

      Hi,

       

      I am a Mathcad beginner, and would like to plot a function against one of the 4 variables it depends on. (I have attached my calc file, the plot I would like is on page 19.) I am able to get a point on the plot, but not a line. I can add another trace, and enter the variable value manually, but this only gives a second point. I know this must be very simple, but I just can't figure it out. I have tried to change Dp to a range (i:1,1.5..4) but with no joy.

       

      Any help greatly appreciated!
