Hi Ortiz,
Sure, Mathcad graphs can do what you ask, you just have to be a little circumspect in how you set up your data structures.
You'll need to use arrays, so start out something like this:
(Note that I use := for : in Mathcad, .. for ;, [ for functional subscript and . for literal subscript)
N:=100 The number of values in your arrays
n:=0,1..N Set up a range on n
Now, fill your two Y ranges in a linear manner like this:
y1.min:=-10
y1.max:=10
y1[n := ((y1.max-y1.min)/N)*n+y1.min
y2.min:=-1
y2.max:=1
y2[n := ((y2.max-y2.min)/N)*n+y2.min
Now, fill your x array however you wish. Let's say you already have some function f that does the job.
x[n := f(y1[n),y2[n)
Then, plot a Mathcad graph, by typing
y1[n@x[n
You're halfway there, now click inside the graph directly after where the y1[n apprears, and type a comma. This will create a blank placeholder directly under y1[n for a second plot. You may have to use the spacebar to get the cursor positioned exactly on the far right side of y1[n otherwise when you type the comma, it will try to add a second index dimension after the n for the y1 array. Type y2[n in the second plot placeholder and you are good to go! You can have as many as 16 different plots on one Mathcad graph. Notice that the graph is basically pairing up values from the y1 array with the x array and the y2 array with the x array. So, you need to make sure that all of these arrays are the same size or it won't work.
Hope this helps!
