LabelAt(axis) - Where to place numerical labels for a Plot

Description:

This attribute controls the appearance of annotated axes by determining where numerical axis labels and associated tick marks are placed. It takes a separate value for each physical axis so that, for instance, the setting "LabelAt(2)=10.0"  specifies where the numerical labels and tick marks for the second axis should be drawn.

For each axis, the LabelAt value gives the value on the other axis at which numerical labels and tick marks should be placed. For example, in a celestial (right ascension, declination) co-ordinate system, LabelAt(1) gives a declination value which defines a line (of constant declination) along which the numerical right-ascension labels and their associated tick marks will be drawn. Similarly, LabelAt(2) gives the right-ascension value at which the declination labels and ticks will be drawn.

The default bahaviour is for the application to generate its own position for numerical labels and tick marks.

Type:

Floating point.

Notes:

• The LabelAt value should use the same units as are used internally for storing co-ordinate values on the appropriate axis. For example, with a celestial co-ordinate system, the LabelAt value should be in radians, not hours or degrees.

• Normally, the LabelAt value also determines where the lines representing co-ordinate axes will be drawn, so that the tick marks will lie on these lines (but also see the DrawAxes  attribute).

• In some circumstances, numerical labels and tick marks are drawn around the edges of the plotting area (see the Labelling  attribute). In this case, the value of the LabelAt attribute is ignored.
