OK, so this has to be an easy one. I am trying to plot a function several times for a variety of values of a constant. For example: y[x_, a_]:=a*x I want to plot a=10, a=20 overlaying one another. Currently I simply rewrite the equation however many times I need to change the variable. For example: DisplayTogether[Plot[y[x, 10], {x, 0, 33}],Plot[y[x,20], {x, 0, 33}],Plot[y[x,30], {x, 0, 33}],Plot[y[x,40], {x, 0, 33}],Plot[y[50], {x, 0, 33}]] I'm plotting this equation 15 times with a increasing in steps of ten. Seems to me there should be a single command to do this rather than cut and paste 10 times (and then go back in to change the variable by hand). Something like in Sum[] where you can state the beginingvalue, end value and step size. Thanks for the help. mary beth -- Department of Chemistry and Biochemistry University of Colorado Chemistry 76 Boulder, CO 80309-0215 (303) 492-0579
