Percentage bar graphs compare the percentage that each item contributes to an entire category. Rather than showing the data as clusters of individual bars, percentage bar graphs show a single bar with each measured item represented by a different color. Each bar on the category axis (often called the x-axis) represents 100 percent.
Charts like this help you to analyze things like how you are spending money each quarter or which salespeople contribute the most sales each month.

Selecting the correct data is especially critical for this type of chart. Including the total in your data selection will skew the results, so remove it if selected:
- Select the Total data series.
- Press Delete.
The total category should disappear from both the bars and the graph's legend.
