I am a Mathcad beginner, and would like to plot a function against one of the 4 variables it depends on. (I have attached my calc file, the plot I would like is on page 19.) I am able to get a point on the plot, but not a line. I can add another trace, and enter the variable value manually, but this only gives a second point. I know this must be very simple, but I just can't figure it out. I have tried to change Dp to a range (i:1,1.5..4) but with no joy.
Any help greatly appreciated!
Solved! Go to Solution.
Firstly I will have to apologise because I currently do not have access to Prime.

If I'm getting you right, you want to plot hg against V.ru, t.g, D.p and delta.h, is this correct?
If so, these will need to be ranges. Can you save the file down to M15 format?
Hi Mike, I want Dp on the x-axis, and hg(Vru,tg,Dp,delta_h) on the y-axis, with Dp varying from 2-4m. I don't seem to have the ability to save in any other formats than xmcd or xps i'm afraid. I have attached a pdf if that is any use.

Do you mean mcdx?
You can try the following steps and see if you can get it to work. The function below and attached can be used to create a range vector instead of a range variable. Try defining D.p with the function and then use the vectorize built in function over hg, that should work.

On another note. Why are you making most of your variables functions of other variables. IMO your worksheet becomes very complicated later on.
I agree, it's horrendous! At this early stage I have them all in, but I hope to settle on some figures and remove them later on. Thanks for all the help - no doubt it won't be long until my next question - i'd be lost without it!
