대화형 툴팁으로 차트 시각화를 개선하세요

Tooltips are a valuable feature that provides users with contextual information about specific data points within a chart. By hovering over or clicking on a data point, a tooltip appears displaying relevant details such as the data value, category, or additional context. This enhances user understanding and interaction, making charts more informative and accessible. Tooltips are particularly useful for visualizing large datasets, identifying trends, and comparing different data points. For instance, in a line chart, tooltips can display the exact value of a data point at a specific time, while in a bar chart, they can show the corresponding category and value.

Several VCL products offer chart components with tooltip support including:

• DevExpress ExpressCharts Suite (part of DevExpress VCL Subscription) lets you create charts with tooltips that display detailed information about each data point.
• TeeChart Pro VCL/FMX by Steema Software allows you to add informative tooltips to your charts, providing users with quick access to data values and context.
• ProEssentials by GigaSoft facilitates the creation of visually appealing charts with tooltips that can be customized to display specific data fields and formatting.
