Assigning time points on X axis

I have a wav file imported as data points. I know the sampling rate is 44.1kHz per sec. I know that the file contains 18, 873 samples. How can I assign time on the x axis in msec?

If your sampling frequency is 44.1 kHz, then one millisecond comprises 44.1 time samples. So, if x represents the vector of 18,873 samples, the following yields integer values on the x-axis representing milliseconds, starting at time zero:
plot((0:length(x)-1)/44.1, x)
