Help with plot

[ksk_10594232]

Hi 

I have a set of values that varies along with elevation. I need help plotting the function but can't figure out how to proceed. I have described my issue in the attached file (prime 7). 

Thank you very much for your support.

Thanks to both of you! I really appreciate it. Unfortunately, I made a mistake in the description. I want the value cu3 to increase by 1 kPa by every meter below the elevation of 25 m. Any suggestions on how to incorperate that into the function?  

Thank you in advance.

Here is what I understood so far from your descriptions:

Of course the functions can be defined in various ways. You may use if and elseif as shown by ttokoro,

you may use nested if-functions similar to what you use in Excel (harder to read) or you may use multiplications with boolean expressions.

Sorry, attached file is Prime 10 format as I don't have P7 installed
But there is nothing hidden, the pictures show all that's necessary, your definitions are unchanged
