# Tools=>LaTeX Formula ConfigurationΒΆ

(TeX is a typesetting system designed and mostly written by Donald E. Knuth. LaTeX is a typesetting system by Leslie Lamport, using TeX.))

With this command LaTeX formulas can be defined. The LaTeX formulas are stored in a text file. The field function @f{latex} can be used to display the LaTeX formula in a Text object.

See LaTeX <http://en.wikipedia.org/wiki/LaTeX>.

**File**

Is the name of a text file with LaTeX formulas. The default file is located in the template directory of UniPlot. The file name is`latex.txt`

. The first time the function is invoked the default file will be copied into the UniPlot user directory.

**Open**

Opens an Dialogbox to edit the formula text.

**Edit**

Opens the following simple editor. The file can also be opened with any other text editor:

Each LaTeX text formula consists of a name followed by an equal sign, followed by the formula text enclosed in double dollar characters. Example:

m_dot = $$dot{m}$$The formula text can be multiline. For multiline formulas, the next line must start with a space. The file can contain any number of formulas. A comments begins with a # sign.

**Comment**

When closing with *OK*, a PNG file is created for each LaTeX formula in the
UniPlot user directory in the directory `LaTexCache`

.
The file names are saved in `_g().oLatex`

.

To insert the field function into a table cell, double click the cell
and then press the button `Insert field function`

.
In the dialog box, select the @f{latex} field function. Choose a formula
from the right list.
