2.19. Character string

A variety of expressions, such as Greek, special characters, mathematical formulas and ruby, can be used as the character strings available for comments and graph titles. The commands enabling to describe them almost follow the commands of TeX and LaTeX. If you are familiar with TeX or LaTeX, it’s very easy. But, if you are new to it, it may feel a little strange. Even if we say so, there are only a few frequently used commands, so you will soon get used to them. First, we will summarize the common principles and the differences from TeX and LaTeX in the following,

• As a general rule, special commands start with ”````” and end with a space in principle.

• Unlike TeX and LaTeX, sequential blanks are regarded as sequential blanks as they are.

• Line breaks in multi-line comments are considered as line breaks, unlike TeX and  LaTeX.

• Some symbol characters are special characters that are not output even if they are input as they are.

The meaning of the special character mentioned above and the commands to output it as it is are summarized below.

Table 2.70 Special characters that cannot be simply output

2.19.1. Overall typeface selection

You can use 4 types of basic fonts in European and 2 types in Japanese. The Western texts are Helvetica, Symbol, Times-Roman, Courier, and the Japanese texts are Mincho and Gothic. Italics (italics), bold (bold), and bold italics (bold italics) are available for each typeface except Symbol. When you specify the font using BFON(\(f\)), TFON(\(f\)) or F(\(f\)), specify it as \(f\) with the following number. Also, you can choose the font for the whole font, the numbers on the axis scales, the font for the comments, and so on, accordingly. If not specified, the default is Helvetica number 0.

Table 2.71 Font type

2.19.2. Change the typeface in the string

The command to change the typeface in the middle of one character string is almost the same as TeX and LaTeX, and the format is below.

{\ff  string }

Here, the character string in {  } is changed to the typeface defined by the two English characters ff. The ff is as follows.

Table 2.72 Commands to change typeface

2.19.3. Character size

In ANGEL , the default character size is determined depending on the location of the string, such as graph title, axis title, legend, comment, etc. These sizes can be changed by a parameter. You can also change the size of the characters in the input string. The command to change the size of a character in the middle of one character string is almost the same as TeX and LaTeX, and the format is below.

{\\(size\) string }

Here, the string inside {   } is changed to the size defined by the alphabetic character \(size\). Unlike TeX and LaTeX, these effects are based on their current size. You can also insert it over and over again. Therefore, there is no \normalsize. The \(size\) is as follows.

2.19.4. Text color

In ANGEL , you can change the color of the text with parameters by the location of the string, such as graph title, axis title, legend, comment, etc. You can also change the color of the text in the input string. The format of the command to change the color of a character in the middle of one character string is

{\color{ \(c\) } string }

Now the string inside {   } is changed to the color defined by \(c\) [1].

[1]

Definition of the color is shown in the line parameters section.

2.19.5. Text box

In ANGEL , it is possible to enclose the entire character string of the legend, multi-line comment, constant display in various boxes by specifying parameters. It is also possible to enclose only a specific string, which is also the input string, in a box. The format of the command to enclose the string in a box is below.

{\\(boxname\){ \(c\) }{ \(cb\) }{ \(cl\) } string }

Here, the string inside {   } is surrounded by a box defined by \(boxname\) [2]. Also you can change the color by \(c\) [3] for the text color, \(cb\) for the background color of box, and \(cl\) for the text color. The color definition can be omitted.

[2]

Definition of \(boxname\) is shown in the BOX: section.

[3]

Definition of the color is shown in the line parameters section.

2.19.6. Chinese character (漢字) ruby

ANGEL makes it easy to insert chinese character ruby. The format is below.

　\ks{ 漢 }^{ かん }

　\ks{ 漢 }_{ かん }

When using ^, ruby is placed on the top of the Chinese character. Meanwhile, when _, ruby is placed on the bottom. An example is shown below.

2.19.7. Special character

The following commands are provided to output special characters.

Table 2.75 Special character

Here, \today,\time,\file,\page can output the date, time, input file name, and number of pages, respectively. The date and time are alphanumerical in default, and to make this a Chinese character, put at least one Chinese character in the \(ks\) part of DATE(\(ks\)) in the parameter section.

2.19.8. Accents

The following commands are available for accents.
