Line Charts
Line charts are useful for showing trends over
time and comparing many data series.
Line charts plot data at regular points connected by lines.
It is best not to use stacked line charts because they are difficult to distinguish from unstacked line charts when there are multiple data series.
The following example shows a revenue trend that peaked in 2012 in every territory.

Line charts can plot data using standard, stacked, 100 percent stacked, and three-dimensional configurations.
