Bar charts are the most common type of business chart and are especially useful for comparative analysis when you want to focus on comparing values and place less emphasis on time. Use a bar chart to illustrate comparisons among individual items.
In a vertical bar chart, items in the y axis form the chart bars. Items in the x axis and z axis itemize the bars.
In a horizontal bar chart, items in the y axis form the chart bars, and items in the x and z axes itemize the bars.
