139            Like Bar charts, Line charts are some of the most versatile chart types. It is similar, but can indicate chronological
140            data better. Line charts are good if, for example, you want to illustrate sales figures over a year (or any period of
141            time). You'll then be able to easily see whether sales are going up, down or are stagnant. It will also become apparent
142            which months are busier than others. By using a multiple line chart you can add multiple sets of data (eg two or more years
143            of figures) to your chart. You can customise the line chart by stipulating it as being filled, having drop shadows, keys,
144            having the X axis in the centre, different colors, different tickmark styles and tooltips etc.
145        </p>
146       
147        <p>
148            The first chart uses external DIVs for the tooltip contents. The DIVs are at the bottom of this page (they're set not to
149            be visible). Using external DIVs for tooltips can make maintenance easier.
