Multiple-Variable Functions and Plotting - New Critical Limitation?

Hi,

I'm trying to switch to Prime. Here is a show-stopper that will have me trying Maple for the first time if I can't get it resolved:

I frequently need to create functions with many input variables (sometimes over 10) and plot the results many ways. To work in a 2-D plot, I used to just set some of the variables to constants in the function name in the plot itslef. This no longer seems to work.

I tried an alternate path of using matrix subscripts, but appear to have hit the same limitation.

Show.Stopper.

Am I missing that this very critical past feature is now entirely gone?

Thanks.

I'm trying to switch to Prime.

My god, why?? Switching means you are using Mathcad 14 or 15 now, right? So why would you voluntarily switch to an inferior version?

2D-plots in Prime have many flaws but what you tried should work, as I understand it. Are you trying to plot a family of curves? Then you should explicitely chose waterfall plot in Prime. This was not necessary in Mathcad and as I had read will not be necessary anymore in Prime 3.

Think it would be a good idea to attach a worksheet (upper right - advanced editor) so we can see what you are trying to do.

Think my remark about the waterfall plot was not appropriate - it refers to plotting matrices.

What I understood from your writing was that you are trying to so something like the attached. It works, but sometimes you have to change the labels of the variables (from variable to none or vice versa) - this is a very annyoing thing in Prime!

Nice.

Its a shame we cannot plot family of curves as in Mathcad 15 and below - at least not the easy way. We would have to create matrices to plot via waterfallplot (which at least will be default for matrices in Prime3). Any chances we get the easy way back?

BTW, what screen capture program are you using? Why is it that ibn your pic we see the single characters the brackets and parentheses are consisting of? Or is this the new to come copy/paste feature of Prime 3ß ? Using a capture prog I get the following:
