In order to understand what a histograph is, we must first know a bit about histograms as histographs are based on histograms. A histogram, in the most simple of terms, can be represented as a bar graph of tabulated frequencies displayed. Examples of such graphs would be what the census bureau uses to show the rise and fall of the population or the differences between lengths of different objects.However, it is said that it is a line chart based on a histogram. Which ever definition you prefer, it all comes down to which one you want to use depending on the data given. Typically, if you have a set of data where the number of classes is below eight, you would want to use a histogram. However, for numbers going above eight, you will definitely want to make use of histographs.
But what types of things can you use these graphs for? One cool way to make use of histograms is to fix your digital images. Some cameras come with live histograms in them that allow you to fix the exposure and shutter speed. Some allow for it during and others after the picture is taken.
An even cooler way to utilize histographs is by treating it like a digital image. Imagine having a project where you had to summarize hundreds of graphs. If you tried to stack all of these graphs on top of one another, that would not work out only look like a complicated and jumbled mess. However, if you instead you utilized it as a histograph, you would be able to make great effects by highlighting what you want everyone to see, and blurring out what you don't. Which ever you choose, both graphs feature their own cool tricks.
