In this image, the histogram is pushed against the left "wall" because there are significant areas of pure black in it, and significant areas of very dark tones.

But in many more realistic images, this sort of histogram would indicate a loss of detail in the darkest areas, blocked up shadows. In a more conventional image where it is desirable to have detail retained in the dark areas, the histogram should taper to just touch the left edge at the bottom corner, as shown here:



The shape of the histogram will vary with each different image. There isn’t a right or wrong way it should look. It is simply a reflection of the tonalities in an image.
