When I was in fifth grade, I vividly remember my unpleasant "computer guidance teacher" telling us about how the mouse "talks to you" if you keep it hovering over one thing long enough. I take it that you mean "a little labeled banner that appears when your mouse hovers long enough over some questionable thing" by "tooltip"; thus, there's the use - if you don't know what it is, hover your mouse over it (just point and don't clikc, that is) and a tooltip comes up explaining what it is.
it was the box which will says about the textbox.
They're called tooltips
Press Tab! :D
Descriptive text for individual data markers, like pie slices in a chart, is typically provided through tooltips or labels. Tooltips appear when a user hovers over a specific marker, displaying relevant information such as the value or percentage represented by that segment. Labels can be directly placed on or near the markers, showing key data points without user interaction. Both methods enhance data comprehension and visualization clarity.
