.SH "Detailed Description"
.PP 
A class representing a scale division\&. 

A Qwt scale is defined by its boundaries and 3 list for the positions of the major, medium and minor ticks\&.
.PP
The upperLimit() might be smaller than the lowerLimit() to indicate inverted scales\&.
.PP
Scale divisions can be calculated from a \fBQwtScaleEngine\fP\&.
