Double-click a numeric axis to customize it using the Axis Settings window. Or, right-click the axis area and select Axis Settings to access the window.
Customization features in the window depend on the data type of the axis and the specific platform JMP uses to create the plot or chart. Figure 8.29 shows a typical Axis Settings window for numeric (continuous) axes.

If you selected a scale type of Log, enter the Base to use.
|
•
|
If you selected a scale type of Power, enter the Power to use.
|
To set a default scale type for a variable, which avoids making this change every time you run an analysis, see Axis in The Column Info Window.
For plots and charts that contain a numeric axis area, you can change the format of the axis. For details about numeric formats, see Numeric Formats in The Column Info Window.
•
|
If you selected Date, Time, or Duration, you need to specify the format of the increments. See Add and Remove Axis Labels. You can also specify label row nesting. See Label Row Nesting.
|
•
|
To add commas to values that equal a thousand or more, select the Use thousands separator option. You must account a space for each comma in the Width box, or else they might not appear. This option is available for the Best, Fixed Dec, Percent, and Currency formats.
|
Note: When you change the numeric format of an axis, you do not change the numeric format of the way the values appear in the corresponding data table. To change how a date or time appears in a data table, see Numeric Formats in The Column Info Window.

Select Reverse Order to reverse the axes by reversing the minimum and maximum values. Note that this option is not supported for ternary plots.
|
Tip: To set a default minimum and maximum axis value for a variable, which avoids making this change every time you run an analysis, see Axis in The Column Info Window.
The example on the right in Figure 8.30 is an enlargement of the point cluster that shows between 80 and 140 in the plot to the left. The enlarged plot is obtained by reassigning the maximum and minimum axis values and changing the number of increments to 20.

If the axis Format is set to Date, Time, or Duration, a format menu appears beside Increment. See Figure 8.31. Select which format you want the increments to take.
Tip: To set a default axis increment for a variable, which avoids making this change every time you run an analysis, see Axis in The Column Info Window.
You can add tick marks to a numeric axis, or change the number of minor tick marks that appear on a numeric axis. In the Axis Label Row panel, be sure to select the Minor Tick Marks box so that the tick marks appear on the axis.
Tip: To set default minor tick marks for a variable, which avoids making this change every time you run an analysis, see Axis in The Column Info Window.
To change the starting point of the tick marks, enter a number in the Tick Offset box. For example, if the Tick Offset is currently set to 0, setting it to 1 will move all the values on the axes up by 1.

You can modify the axis label font on any axis type. Your changes only apply to the active graph. To set the default axis label font, see Fonts in JMP Preferences.

Select Automatic Font Size to have JMP attempt to decrease the font size (down to a certain minimum) if all of the labels cannot fit at the default size.

These options can vary depending on whether your axis is continuous or categorical. Figure 8.33 shows axis settings for a categorical axis. Figure 8.29 shows axis settings for a continuous axis.
