114    <p>
115        This page shows how the setting <i>chart.filled.accumulative</i> affects your charts. The chart on the left has
116        it enabled (the default), so the lines in effect sit on top of each other. The chart on the right has the setting
117        set to false so the points are drawn "as-is", ie not accumulatively. The first chart could be more useful if you wish
118        to see accumulated values, whereas the chart on the right might be better if you want to see individual values.
119    </p>
120   
121    <p>
122        Keep in mind that if you choose to use a non-accumulative chart the colors may be better as semi-transparent ones,
123        otherwise parts or all of some lines may get hidden by others.
