Data Cursor — Displaying Data Values Interactively
Note Surface plots and 3-D bar graphs can contain NaN values. If you drag adatatip to alocationcoded as NaN, the datatip will disappear (because its coordinates become (NaN,NaN,NaN)). You can continue to drag it invisibly, however, and it will reappear when it is over a non-NaN location. However, if you create a new datatip while the previous current one is invisible, the previous one cannot be retrieved.
Datatips on Image Objects
Datatips on images display the x-and ^-coordinates as well as the RGB values and a color index (for indexed images), as show below:
50. 100 150 200 250 300
Datatips on 3-D Objects
You can use datatips to read data points on 3-D graphs as well. In 3-D views, data tips display the x-, y- and ^-coordinates.
