A histogram is a display of statistical information that uses rectangles to show the frequency of data items in a successive numerical intervals of equal size. In most histograms the independent variable is plotted along the horizontal axis and the dependant variable is plotted along the vertical axis. The data appears as colored or shaded rectangles of variable area . Some histograms are presented with the independent variable in the vertical axis and the dependent variable in the horizontal axis.
In Photography
Histograms are used to indicate the range of gray tones from absolute black to absolute white that are captured in a photograph. The tone axis typically runs horizontally from left to right. The number of tones indicated can vary. Absolute black is at one end and absolute white is at the other end. The tone in the middle will be what is called "Middle Gray" in photographic terms.
The height of the bars indicates the amount of each tone that appears in the scene photographed. A very contrasty photo would have a histogram that looks like a valley between two very high peaks on either end. The bars on the White end and the bars on the black end would be very tall and the bars in the middle would be very low. A good goal would be to have a relatively good distribution of tones across the range from black through middle gray to white. It does not need to show a flat profile - in fact it shouldn't.

What are neat diagrams?
Neat diagrams are the diagrams that are neatly made either on computer such as pie charts, histogram etc. or drawn with hands. These are easy to interpret and understand.
Word beginning with the letter h?
Officially, yes. Most teachers/professors will accept it either way. ANSWER In American English, it depends on whether or not the "h" is sounded. In "hour," it is not sounded; therefore, we say, "an hour." In "hostage," it is sounded; therefore, we say, "a hostage." [Some U.S.A. dialects use "a" in some words even when the "h" is not sounded. In the South, for example, one hears, "I'll be back in a (h)our."] That view rests on the general rule that if a word begins with a vowel we use "an," if it begins with a consonant, we use "a." Some h-words have alternate pronunciations, with the h and without. For example, the word "homage" is homage or omage -- or, in modern film lingo "ohMAGE." In America, we would say, "a homage"; "an omage"; "an ohMAGE." [spelvin]
