27.7.3.1 The (Options) Axis Tab

Settings on this tab control various graph axis format options.

1 Max. Number of Ticks Group
2 Distance from Tick Labels (%) Group
3 Tick Labels Display
4 Unit Display for Axis Title

Max. Number of Ticks Group

Numeric Scales	The Numeric Scales combination box value determines the maximum number of major ticks that can be displayed in a graph window when Numeric is selected from the Type drop-down list on the Tick Labels tab of the Axis dialog box. If the # Major Ticks radio button is selected on the Scale tab of the Axis dialog box and the value in the associated text box exceeds the Numeric Scales combination box value, then Origin displays a maximum of six major ticks in the graph window.
Text/Date Time Scales	The Text/Date Time Scales combination box value determines the maximum number of major ticks that can be displayed in a graph window when Text from Dataset, Time, Date, Month, or Day of Week is selected from the Type drop-down list on the Tick Labels tab of the Axis dialog box. The default value is 400. If the amount of major ticks exceeds the Text/Date Time Scales combination box value, then Origin displays a maximum of six major ticks in the graph window. (affected when the Type of Major Ticks is set to By Increment or By Counts on the Scale tab of the Axis dialog box.) Note: When the Type of Major Ticks is set to By Dataset, the Maxinum number the major ticks will be affected by @ATDM and @ATDS, instead of this control.

Numeric Scales

The Numeric Scales combination box value determines the maximum number of major ticks that can be displayed in a graph window when Numeric is selected from the Type drop-down list on the Tick Labels tab of the Axis dialog box.

If the # Major Ticks radio button is selected on the Scale tab of the Axis dialog box and the value in the associated text box exceeds the Numeric Scales combination box value, then Origin displays a maximum of six major ticks in the graph window.

Text/Date Time Scales

The Text/Date Time Scales combination box value determines the maximum number of major ticks that can be displayed in a graph window when Text from Dataset, Time, Date, Month, or Day of Week is selected from the Type drop-down list on the Tick Labels tab of the Axis dialog box. The default value is 400.

If the amount of major ticks exceeds the Text/Date Time Scales combination box value, then Origin displays a maximum of six major ticks in the graph window. (affected when the Type of Major Ticks is set to By Increment or By Counts on the Scale tab of the Axis dialog box.)

Note: When the Type of Major Ticks is set to By Dataset, the Maxinum number the major ticks will be affected by @ATDM and @ATDS, instead of this control.

Distance from Tick Labels (%) Group

To Inside Ticks	Type or select the default distance of an "inside tick" from the tick label, in a percentage of the tick length.
To Outside Ticks	Type or select the default distance of an "outside tick" from the tick label, in a percentage of the tick length.
To Axis Title	Type or select the default distance of the axis title from the tick label, in a percentage of the tick length.

Tick Labels Display

Zero is '0'

Always display the zero point label on the axis scale as '0', overriding other format options (e.g. Set Decimal Places = 2).

Please note, a system variable @TLC can be used to control this option.

No Trailing Zero

Always remove trailing zeros from axis tick labels, overriding other format options (e.g. Set Decimal Places = 2).

Please note, a system variable @TLC can be used to control this option.

Display 1 and 10 as 10^n for Scientific :10^3 Format

Check this check box to display 1 and 10 as 10^n when the Display item of Tick Labels has been set to Scientific: 10^3.

Scientific :1x10^3 Display

Use this drop-down list to specify how to show the Scientific format(10^3) when the Display item of Tick Labels:1×10^3,1 × 10^3, 1x10^3, 1·10^3.

Note: Before Origin 2021, you can only use the check box Display 1×10^3 as 1·10^3 for Scientific :10^3 Format to show the Scientific format(10^3) as 1×10^3 or 1·10^3, just like:

Since Origin 2021, Origin supports to also show the Scientific format(10^3) as 1×10^3 or 1 × 10^3 which both contain the real multiple sign ×(Unicode x(00d7)), not character x.

Scientific: 1E3 Display as

Use this drop-down list to specify how to show the Scientific format(1E3): 1E+03, 1E+3 or 1E3. The default setting is 1E+03.

Note: You can use the system variable to change the setting for this drop-down list:

When you set @ete to 1, the Scientific: 1E3 Display as drop-down list will be changed to 1E+3.
When you set @sss to 0, the Scientific: 1E3 Display as drop-down list will be changed to 1E3.

Unit Display for Axis Title

To control unit display for axis title, (a) pick an option from the fly-out button, or (b) type a custom notation string directly into the edit box. The custom string can include literal text.

menu option	text box displays	axis title displays, for example ...
<auto>	<auto>	depends on value language version and values of system variables @LUQ and @LUQO (see Notes).
<none>	<none>
(<U>):(Unit)	(<U>)	Displacement (mm)
[<U>]:[Unit]	[<U>]	Displacement [mm]
{<U>}:{Unit}	{<U>}	Displacement {mm}
/<U>:/Unit	/<U>	Displacement /mm
-<U>:-Unit	-<U>	Displacement -mm
in <U>:in Unit	in <U>	Displacement in mm
%(CRLF)<U>:Unit in 2nd line	%(CRLF)<U>	Displacement mm

Notes:

Preferences sets on the Options: Axis tab will be the default. Use of system variables as described in these notes is generally only necessary when you need a temporary change of default behavior (e.g. you are generating a series of plots by script and you set a temporary value for @LUQ for the session only).
You can use the system variable @LUQ to set unit display: -2 = custom, -1 = auto, 0 = disable, 1 = (unit), 2 = [unit], 3 = {Unit}, 4 = / Unit, 5 = - Unit, 6 = in Unit. In most case the values of @LUQ and @LUQO are the same, but in some special case, @LUQ will be translated to the real value, meanwhile another system variable, @LUQO will keep the original set value. If Unit Display for Axis Title is set to <Auto> and current language is German, @LUQ will translate to 2, meanwhile @LUQO still equal to -1.
If you choose unit display of / <U> or - <U>, there is one space before separator by default. To trip the space, set system variable @ATSS = 0.
To add unit as to tick labels as prefix/suffix, use options in the Tick Labels tab of Axis dialog.
