DISPLAYING INTERACTIVE CHARTS ON DEVICES WITH LIMITED RESOURCES

摘要

A server provided according to an aspect of the present disclosure receives as input, data values to be displayed in the form of a chart. The server renders the chart based on the received data values and also generates a static image for the rendered chart. The server, in addition, creates an area map indicating the portions of the static image, which correspond to the respective data values, and are interactive. The static image and the area map are served to devices, which are able to display the chart for interaction, with minimal resources in view of the availability of the static image as well as the area map.
