What are axes and tick marks?

Axes extend the entire length of the graph scale along each axis. Tick marks provide reference for points on a scale. Each tick mark represents a specified number of units on a continuous scale, or the value of a category on a categorical scale.

Axes

The x (horizontal) axis and the y (vertical) axis are noted on the graph.

Tick marks

The items with the label "1" are examples of major tick marks and the items with the label "2" are examples of minor tick marks. Minor tick marks can be used only with continuous scales that contain infinite numerical points between ticks, not with categorical scales that represent only distinct categories.

Change the number and position of major tick marks

  1. Double-click the axis that you want to change.
  2. On the Scale tab, under Major Tick Positions, choose Position of ticks.
  3. Enter your tick mark positions either as a list of numbers with a space between each number, in the format minimum: maximum/spacing, or a combination of both.
    For example, to specify tick marks at 1, and at every even number from 2 to 10, enter either 1 2 4 6 8 10, or 1 2:10/2.
  4. Click OK.

Add minor tick marks to a graph

  1. Double-click the axis on which you want to display minor tick marks.
  2. Click the Show tab.
  3. Under Low, select Minor ticks.
    This adds the default number of minor tick marks between the major tick marks.
  4. (Optional) Click the Scale tab. Under Minor Ticks, deselect Auto and enter the number of minor tick marks to display between consecutive major tick marks.
  5. Click OK.

Include minor tick marks when you create a graph

  1. In the dialog box for the graph you are creating, click Scale.
  2. On the Axes and Ticks tab, under Show, select Minor ticks.
  3. Click OK.

Include minor tick marks when you create a graph with command language

Use the NMINOR subcommand to include one or more minor tick marks between consecutive major tick marks.

For example, to display one minor tick mark between consecutive major tick marks on the x-axis of a scatterplot, use:

Plot C1 * C2; 
Scale 1; 
LDisplay 1 1 1 1; 
NMinor 1.
