Overview
Tool tips are small annotations that can be set to appear as the user moves their mouse over a chart element. These small information pop-up windows can contain any type of information including a message about the element they represent, the value of a single data point, or they can be used to give the user other information as needed. This article describes how to use tool tips with the Dundas Chart for SharePoint™ web part.
