Add case names to plot
h = gname(cases,line_handle)
a figure window and waits for you to press a mouse button or a keyboard
key. The input argument
cases is a character array
or a cell array of character vectors, in which each row of the character
array or each element of the cell array contains the case name of
a point. Moving the mouse over the graph displays a pair of cross-hairs.
If you position the cross-hairs near a point with the mouse and click
once, the graph displays the label corresponding to that point. Alternatively,
you can click and drag the mouse to create a rectangle around several
points. When you release the mouse button, the graph displays the
labels for all points in the rectangle. Right-click a point to remove
its label. When you are done labelling points, press the Enter or Escape key
to stop labeling.
gname with no arguments labels each case
with its case number.
cases typically contains unique case names
for each point, and is a cell array of character vectors or a character
matrix with each row representing a name.

This example uses the city ratings data sets to find out which cities are the best and worst for education and the arts.

Click the point at the top of the graph to display its label, “New York.”
