Creating bar graphs

As bar graphs are very easy to understand, they are the most common type of graphs. The graphs that have a horizontal orientation are called bar graphs and the graphs that have a vertical orientation are called column graphs. The length of the bar represents the quantity of a particular measure. They are best used with categorical information, such as gender, state, regions, countries, business types, and others. One very important thing to note with the column bar charts is that this type of chart's y axis must always start at zero, otherwise it is very difficult and misleading to encode the length of the bar to a measure.
