What have you tried? Where did you have a problem, specifically?
Is basic plot with multiple lines; put the data in an array and call plot(); saving the line handles
hL=plot(x,y);
then set the linestyles, colors of the line handles as desired.
scatter only accepts vectors, not an array, so it's more effort -- you don't have to have a line drawn w/ plot so it'll handle the data vector just as well as would scatter
