By default axes are produced automatically with large tick marks at convenient positions and small tick marks in-between. Owing to the great variety of number ranges it is not always possible to provide ideally spaced tick marks. This command allows the user to specify their own positions for the large tick marks.
For the X and the Y-axes the user is prompted for automatic positions or not. If non-automatic positions are selected, the user will be prompted for the start position (in data coordinates), the interval between large tick marks (data coordinates) and the number of large tick marks to draw on the axis. (The number of large tick marks is defaulted to a value which covers the axes, but not outside.)
