histogram

The values themselves go along the bottom axis, and the height of each bar is how many cases fell into that slice of the range. It is not a bar chart of categories, it is a picture of a set. What you are looking for is shape: one hump or two, a long tail on one side, a gap where nothing landed. Bin width changes the shape, so pick it once.

Best when you have many measurements of one thing and want to see where they pile up.
