A range area chart fills the space between low and high value boundaries, making it easy to visualize how a continuous range changes over time or across categories.
This sample compares CD sales of the A2 band across 12 months, with the lower boundary representing year-2000 figures and the upper boundary showing year-2010 figures. The filled area between the two lines highlights the sales gap. Hovering any point reveals a tooltip with both the 2000 and 2010 values for that month.
Follow the step-by-step Range Chart Tutorial to learn how such charts are built. See the Range Chart documentation for all configuration options.
