30 Use the toolTip-function with mouse-over and mouse-out events (see example below).
32 - To show a tooltip, use this syntax: toolTip(text, width in pixels, opacity in percent)
33 Note: width and opacity are optional. Opacity is not supported by all browsers.
35 - To hide a tooltip, use this syntax: toolTip()
