You can use this to set a list of tips to be shown as popups when the mouse is over any data-point. This is implemented for HTML pages output as VML or as mapped images.

ch.Set 'Tips' 'One' 'Two' 'Three'

A typical use would be for a scatter-plot where extra information about each data point could be shown to the user. To show tips on multiple data series, pass an array of tip values which match exactly the structure of the data.

ch.Set 'Tips' (2 3½'One' 'Two' 'Three' 'Four' 'Five' 'Six')

You must set tips for all the data-points if you use this property – if you only want to set tips on a small selection of points consider calling ch.Tip instead, as this can be called repeatedly to set tips on individual points.
