Setting y-axis positive down

Hello,

How do I set positive y-axis  in the downward direction in prime?

 

Regards,

Sam

It was easy to do so in real Mathcad but you can't do that using Primes native plots.

In Prime you may have a look at the Chart component which has quite some drawbacks (slow, awkward, not scaling, no units,...) but it provides labels, grid lines, a secondary y-axis and you also can reverse the axis.

 

BTW, its sure not ideal but a workaround using Primes native plot sometimes can be plotting the negated values at the y-axis as shown here: Derive output as a Matrice

Thank you!

 

Hello Werner, I posted a question few days ago and got no answer, about iteration or try to have the mathcad sheet go thru a list of sections until it finds a section that satisfies certain criteria. Would you have time to look into it?

You are referring to the question where you got an answer by @terryhendicott  ?
I saw it and as far as I remember I had a quick look, but with 24 pages and collapsed regions it was too large/confusing for me. Especially as I don't have access to a Prime licence at the time and probably would not be able to (re)calculate the sheet, I decided not to further tackle with it. Sorry!

Superficially, and without having looked at the worksheet in detail, it could be promising to implement the calculations of the individual “sections” as a function and then call these functions in a program one after the other until the desired result is achieved. But I am in no way sure that this is the perfect approach to choose or if its possible to do so anyway.
