Example of an Overlay Plot
Note: To plot data over time, you can also use Graph Builder, bubble plots, control charts, and variability charts. For complete details about Graph Builder and bubble plots, see Graph Builder in the Essential Graphing book. Refer to Control Chart Builder and Variability Gauge Charts in the Quality and Process Methods book for information about control charts and variability charts.
This example uses the Stock Prices.jmp data table, which contains data on the price of a stock over a three-month period.
