A bar chart or bar graph is a chart with rectangular bars with lengths proportional to the values that they represent. The bars may even be plotted horizontally.
Bar charts are used for plotting discrete (or 'discontinuous') information i.e. information which has discrete values & is not continuous. Some examples of discontinuous information include 'shoe size' or 'eye color', for which you would use a bar chart. In contrast, some examples of continuous information would be 'height' or 'weight'. A bar chart is useful in the event you are trying to record definite information whether it is continuous or not continuous information.In the next blog we will learn about bar graph examples and factoring quadratics.Hope you like the above example of bar graphs,please leave leave your comments if you have any doubts.
