Axis Properties Dialog

Axis Properties dialog box should be used to change various parameters of the selected axis, grouped on three tabs: Scale, Labels and View.

Automatic scale - if checked, DM2003 graphic engine will execute data scaling cycle prior to plotting. You may define non-zero scale margins to expand automatically calculated axis range up to 25%.
Manual scale - allows you to define axis range manually. Note that minimum value may be greater than maximum.
Axis expression allows you to transform appropriate coordinates of all points in all series (including functional series). Although column identifiers are allowed in the axis expressions, probably you will use only cx/cy parameters that represent point coordinates. See expression syntax for more details about available functions, operators and parameters.
As of build #325, axis may be linked to another axis (X or Y). In this mode, axis has no own coordinate scale. Instead, it is used to display additional labels at the positions of primary axis. These labels are calculated using axis expression and values of labels of the main axis. This feature allows you to display simultaneously not only two units of some value (such as inches and centimeters), but any symbolic transformation such as frequently used direct and reciprocal temperature.

Numeric format - allows you to specify format type, minimal width and number of places after decimal point for axis labels.
Date and Time format - input date and time specifier string or select from several commonly used formats.
Warning: not any available scale range can be represented as date/time!
Font button - click to change labels font and color.
Caption - use this field to edit axis caption. It may be used to describe your data.
Labels and/or Ticks may be hidden if you clear appropriate flags.
Expression may be displayed in the axis title (if it is not empty).

You may define number of major (long) and minor (short) ticks. Note that actual number of major ticks may differ in Smart ticks mode (when tick positions are specially calculated to make labels more "readable"). Also you can change ticks direction (inside or outside axis frame) and length (relative to the tick label font size).
Use this tab to select axis color and line width. If you clear "Axis is visible" flag, axis will be invisible.

If you check "Show grid lines" flag, these lines will be plotted at the positions of major ticks. You can change grid line attributes such as width, style and color.
