I'm new to Mathcad, I had the software installed just this morning.
I am having trouble getting my plot to display properly. I played around with my variables and it seems like Mathcad is unable to recognize the variable Cstar (please see the attached file). I tried moving the variable block around and replacing it with single value (in case it was my syntax that was off) but still could not get it to work.
I'd greatly appreciate any help and/or advice on how I should proceed. Thank you in advance!
Solved! Go to Solution.
You can only take the logarithm of a dimensionless value. But Cstar/Nav has the dimension 1/volume. You have to multiply by a volume unit like m^3.
Alternatively you can use a logarithmic scale (see the second plot).
