Hit-testing

The Weather in London chart showing Temperature (°F) series, Pressure (mbar) series, Humidity, % series.


This demo illustrates the interactive capabilities of the DevExpress MVC Chart extension, in particular, a capability to access any chart's element via hit-testing.

In this demo, after the mouse cursor crosses over a chart's element, the detailed information is shown over the chart. This information describes the highlighted object and shows its underlying data (if any). If there are multiple objects layered under a test point, their hierarchy is reflected.

This demo is marked as "updated" because a hyperlink element has become accessible by hit-testing.
