** Y-Axis is intensity. Simple enough. The taller a peak, the more of something there is. If you take the area underneath a peak and add it up (integrate it), you can now say something about how much of something exists and begin to quantify it.

** X-Axis has quirks:
*** It technically represents the amount the frequency of whatever is being analyzed is shifted from the signal from TMS (which is used for calibration and whose single peak is considered to be at 0ppm).
*** It technically represents the amount the frequency of whatever is being analyzed is shifted from the signal from [https://en.wikipedia.org/wiki/Tetramethylsilane Tetramethylsilane]. TMS is a commonly used for calibration and whose single peak is defined to be 0ppm.
*** Also, 0 starts from the right side. Higher frequencies are to the left 0 on the X-Axis (Historical Quirks)

*** Technically, we are measuring how many Hertz higher something is than where the signal for TMS is.
