169            The bar chart is probably one of the most widely used of charts, and also one of the most versatile. It's defined as a chart with
170            rectangular bars with lengths proportional to the values they represent. The bar chart can be used to represent two
171            or more values. With grouped and stacked bar charts, you can visualise two or more sets of data. For example two years
172            worth of sales figures. Doing this you will be able to easily see differences, for example a better year when it comes
173            to sales. You can also show negative values by having the X axis in the center, like the examples shown. If you use a
174            grouped or stacked bar chart, a key may be helpful to your users.
175        </p>
176       
177        <p>
178            By using the tooltips feature, you can provide more detail about what a particular bar represents. The tooltips in
179            <b>RGraph</b> can contain wide range of HTML, so you can use them to show photos or movies for example.
