A scatter chart plots individual data points by two numeric variables, making it effective for tracking observations alongside forecasts and highlighting threshold zones with color-coded range markers.
This sample charts observed and forecast stream levels over a date-time x-axis with color-coded horizontal range markers for flood categories: Action, Minor, Moderate, and Major. Text markers label each threshold, a dashed line marks the historical record at 30.7 feet, and a vertical line marker indicates when the graph was created. The right y-axis uses a logarithmic scale for stream flow, and the legend includes a custom entry for the creation timestamp.
Follow the step-by-step Scatter Chart Tutorial to learn how such charts are built. See the Scatter Plot documentation for all configuration options.
