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

This demo illustrates the interactive capabilities of XtraCharts, in particular, a capability to access any chart's element by hit-testing.

In this demo, after the mouse cursor crosses over a chart's element, a tooltip appears which specifies the object which has been highlighted, 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.
