A system for visually enhancing a chart of one or more data sets with semantic information, the data points in the data sets being values of one or more measures. The system includes a data model that specifies the one or more measures and includes measure annotations for the one or more measures. The measure annotations include semantic information of the measures. The system further includes a processor that executes instructions stored in the memory to implement a chart component. The chart component renders data points of the one or more data sets in a chart, and visually enhances the chart with semantic information of the one or more measures retrieved from the data model.
