| Time Axis Controls |
The horizontal slider is used to specify the number of columns (amount of space) for drawing each interval on the time axis, where interval is the value indicated with the Per Interval option. These options can be used to scale the size of the Gantt chart.
The Per Interval combo box indicates the duration unit to use for scaling the size of the Gantt chart. The Columns option indicates the number of columns (amount of space) available for drawing each specified interval on the time axis.
