# Line charts

Like Bar charts, Line charts are one of the most versatile chart types. It is similar, but can indicate chronological data better. Line charts are good if, for example, you want to illustrate sales figures over a year (or any period of time). You'll then be able to easily see whether sales are going up, down or are stagnant. It will also become apparent which months are busier than others. By using multiple line charts you can show multiple sets of data (eg two or more years of figures) to your charts. You can customise line charts by stipulating them as being filled, having drop shadows, keys, having the X axis in the centre, different colors, different tickmark styles and tooltips etc.
