Interactive Features

To make your charts more engaging and useful, you can add interactive features that help users explore the data in depth. Three of the most impactful interactive options in ECharts are tooltips, legends, and data zoom controls.
Tooltips appear when you hover over a data point or axis, showing detailed information about the value, category, or series. You can configure the tooltip option to trigger on the axis or item, and customize its appearance using properties like backgroundColor, borderColor, and textStyle. This makes it easy for users to get more context about specific data points without cluttering the chart.
Legends allow users to toggle data series on and off by clicking the legend entries. This is managed through the legend option, where you can define which series are shown by default and customize the legend's look. Interactive legends help users focus on particular data series and compare trends more effectively.
Data zoom controls let users zoom in on a specific range of data or pan across the chart. By adding the dataZoom option, you can include both slider and inside (mouse or touch drag) zoom types. This is especially useful for charts with a lot of data points, as it enables users to examine details or spot trends in different sections of the chart.
Combining tooltips, legends, and data zoom gives users a powerful way to interact with your charts, making dashboards more dynamic and insightful.
