126.96.36.199 Label (command)
Places a text label on the page.
label [options] message
By adding one or more option switches you can modify the manner in which the label is created. The message to be displayed by the label is always the final argument. The label command allows multiple option switches. When -xb, -yl, -xt, -yr, -zf, or -zb are used, they must be the final option (immediately preceding the label message). Also, when -n is used, it must be the final option (immediately preceding the label message). Options can be combined only when it makes sense to do so and when they do not conflict with each other.
In addition to entering literal text for message, you can specify $[OMGfileName].Section.Title. This enables you to access a string title in a message file. The OMGfileName extension is assumed to be OMG. If OMGfileName is not specified, the ORIGIN.OMG file is assumed. For an example using this syntax, see the Type command.
Note--Using Escape Sequences to Control Text Format:
You can use escape sequences in a string to customize the text display. These sequences begin with the backslash character (\). All text objects (those created with the label command or with the Text tool) as well as text plotted from a Label column will display according to the rules of these sequences.
The following text formatting commands are available:
|\(ASCII character code)
||Displays the specified ASCII symbol. For example
\(65); // Means "A"
||Format text as superscript.
||Format text as subscript.
||Format text1 as subscript, text2 as superscript.
||Display a bar above text.
||Display a short line - a dot - above text.
||Add tilde above text.
||Format text as bold.
||Displays text in the color located at position number in the Color drop-down lists. For example:
\c4(This is blue); // Set font color as blue
||Displays text using the fontname font. You can abbreviate font name, as long as you use enough letters for the name to be unique.For example:
\f:Times New Roman(This font is "Times New Roman");
||Format text in Greek symbols. For example:
\g(a); // Shows alpha
||Block substitution notation. For example:
\h(\l(1) %(?Y)); // display literal \l(1) %(?Y)
||Format text as italics.
||Change the point size of text. 200 doubles the size, 100 results in no change, etc. For example:
\p200(Double font size);
||Strike the text.
||Insert one conditional horizontal space in a string even there are multiple consecutive spaces. For example:
\b(%(1Y,@LL)\sc%(1Y,@LD3)\sc%(1Y,@LD4)\sc(%(1Y,@LU)))//assume @LD3 and @LD4 not exist, so there will be two spaces. \sc make one space only
||Underline the text.
||Override interpreting escape sequences, so that \n is not recognized as New Line, and \r is not recognized as Return, etc. For example:
// Path cannot be shown correctly if not using \v()
label -p 0 0 -s \v(My UFF is: %Y);
The following characters are supported, some of them are non-printable:
||Single quote mark
||Double quote mark
||Full height prime
||Full height double prime
||Combining double prime
||ASCII character in hexadecimal notation, where hh are two hex digits
Note: Some escape sequences may be not listed in above two tables, you can see User Guide for more information.

The following script creates a label that reads New Label Text which is center justified and named MYLABEL. It draws the label in quadrant 3 of the active layer of the active window.
label -q 3 -j 2 -n MYLABEL New Label Text;
The next script creates a bottom X axis label Maximum Current.
lab -xb (Maximum Current);
The next script updates the content of the label named myLabel with run time values. Note that you could also set up the label with the same text with the Link to Variables option enabled in the Label Control dialog box (see the next example).
%A = "position = $(x)";
label -s -n myLabel %A;
The next script creates a label named myLabel with the Link to Variables check box in the Label Control dialog box selected. The label displays the current value of the x system variable, which is the current X coordinate of the Screen Reader, Data Reader, or Data Selector tools.
label -sl -n mylabel "position = $(x)";
This script shows how to add the file path as graph label, and delete it after exporting the graph. %G and %X are string registers for the current file name and path, while \v() is a escape sequence.
