I am trying to draw a set of curves for a two parameter system.

x:=1,2..3
y:=1,2..10

f(x,y):=x*y^2

I want lines for x=1,2,3. My mathcad guide says you can get rid of the "flyback" to zero using the draw option in the plot menu but I cannot find it anywhere.

Anyone know some good tips for doing this?

The only way I know how to do this, is to write on the ordinate of the graph f(1,y), f(2,y) and f(3,y) to get the curves separately. The abscissa would be y, of course.
 
There was an option to change from lines to draw in old versions when using arrays of data.
The recent versions dropped 'draw' but won't plot lines going off the plot area, so set the limits just before the end points. It also depends on whether you are plotting a matrix or 3 function evaluations.
There was a few threads a while back on that on the collaboratory (Help>> User Forums). Ignore unhelpful responses by some ;-)
