Hi, I'm wondering how to extend the pwelch x range of a function. by default, if you were to plot pwelch(X), the default range is from 0-1. Is there any way to change this range to calculate the normalized frequency from, say, 0-10? Thanks.

Multiply the result from pwelch by 10. :-)

The frequency axis goes from DC (0 Hz) to π radians or the Nyquist frequency (half the sampling frequency) if that information is provided. The only way to change the frequency axis would be to resample the signal to a higher sampling frequency, in this instance, 10 times the original sampling frequency.
