rotateyticklabel

PURPOSE ^

Rotates tick labels

SYNOPSIS ^

function th=rotateticklabel(h,rot,demo)

DESCRIPTION ^

 Rotates tick labels

 TH=ROTATETICKLABEL(H,ROT) is the calling form where H is a handle to
   the axis that contains the XTickLabels that are to be rotated. ROT is
   an optional parameter that specifies the angle of rotation. The default
   angle is 90. TH is a handle to the text objects created. For long
   strings such as those produced by datetick, you may have to adjust the
   position of the axes so the labels don't get cut off.

   Of course, GCA can be substituted for H if desired.

   TH=ROTATETICKLABEL([],[],'demo') shows a demo figure.

   Known deficiencies: if tick labels are raised to a power, the power
   will be lost after rotation.

   See also datetick.
