The Highlighter plugin will highlight data points near the mouse and display an optional tooltip with the data point value. By default, the tooltip values will be formatted with the same formatter as used to display the axes tick values. The text format can be customized with an optional sprintf style format string.

The Cursor plugin changes the mouse cursor when it enters the graph area and displays an optional tooltip with the mouse position. The tooltip can be in a fixed location, or it can follow the mouse. The pointer style, set to "crosshair" by default, can also be customized. Tooltip values are formatted similar to the Highlighter plugin. By default they use the axes formatters, but can be customized with a sprintf format string.

Tooltips can be displayed with Pie Charts. Cursor tracking doesn't work with Pie Charts since they do not have points or axes, so the tooltip is based on the highlighter and always follows the mouse. You may wish to change the background and border colors of the highlighter tooltip for use with Pie Charts, since the default tooltip colors are designed to be displayed on top of a white background, while the Pie Chart slices provide a darker color background for the tooltips. To change the tooltip colors or other attributes, modify the jqplot-highlighter-tooltip class in jquery.jqplot.css.
