Text - almarklein/visvis GitHub Wiki

Visvis supports rendering of text. It has a Label class and a Text class, which are a wibject and a wobject respectively. Both are able to produce a single line of text oriented at a certain angle.

See the text example.

Characters are available for the following unicode sets:

• u0020 - u003f numbers
• u0040 - u00bf alphabet
• u00c0 - u037f latin
• u0380 - u03ff greek
• u2000 - u23ff symbols

Text can be formatted using the following constructs (which can be mixed):

• hello^2 or hello^{there}, makes one or more charactes superscript.
• hello_2 or hello_{there}, makes one or more charactes subscript.
• hell\io or hell\i{ohoo}, makes one or more charactes italic.
• hell\bo or hell\b{ohoo}, makes one or more charactes bold.
• hello\_there, a backslash escapes, thus keeping the _^ or \ after it.

There are several escape sequences for (mathematical) characters that can be inserted using the backslash (for example \infty). People familiar with Latex know what they do:

Note: In case one needs a character that is not in this list, one can always look up its unicode value and use that instead.

Letters from the greek alfabet can be inserted in the same way (By starting the name with an uppercase letter, the corresponding upper case greek letter is inserted):
