Histograms are used to display graphically continuous variables. They are relevant in many areas including digital photography, census data, actuarial statistics and, as we shall see, signal measurements in an oscilloscope.

In digital photography, an image histogram is a graphical representation of the tonal distribution. The graph depicts the number of pixels for each tonal value. In post-processing, the artist can, by using on-screen sliders or by typing in numeric values, alter various parameters such as hue and intensity, and observe the changing histogram as the photo’s appearance evolves.
