ezplot of function x = constant

Hi, i am trying to ezplot the function X = constant (to overlay with other plots) using the following command:

n = ezplot(x-P*Sf/Tc,[0,0.25]); set(n,'Color','r')

Where P, Sf, Tc are constants

however, when its plotted i actually see a line with a positive slope, which suggests that it is not being interpreted properly.

Any ideas on how to do this?

Please provide the code you actually used to run that command. I can’t get it to run, so I can’t figure out what the problem is. It would help to know what x, P, Sf, and Tc are.

they are just constants

in this case:

P = 1E-5 Sf = 540*10^6 Tc = 0.8*10^6

I dont have access to the code at the moment, but theres not much more too it than that
