Line
Documentation
Line chart series types help visualize data trends over specified intervals. In this example, you can switch between the line, stacked line and full-stacked line series types. Stacked line series help visualize multiple series and compare the manner in which each series contributes to the total aggregate value for specific arguments. Full-stacked line series help compare the percentage value of multiple line series for each argument.
