Interpretation of color histogram

I'm reading a paper about image processing and came across this color histogram: image. But I'm not sure how to interpet it. The 3 different curves are for red, green and blue. But what is on the X and Y-axis? My guess would be X-axis going from 0 to 255 for the 'intensity' of the color and Y-axis the amount of pixels in the image that have this intensity. Could anyone confirm this or correct me if I'm wrong?

If I know well, someone please correct me if I am wrong, the X axis represents the possible values of a color from either one of the RGB channels (a value in the [0-255] interval), and the Y axis represents the number of pixels having that value.
