4. The Menu Entries

4.1 File

New Plot File

Opens a new plot file to insert items using the dialog Items.

Open Plot File

Opens an existing plot file.

In a plot file all settings of a graphical presentation are stored in ASCII format.

In case of activated setting Autoplot the graphical presentation is displayed immediately.

Open Data File

Opens an existing data file.

The numeric values have to be arranged in rows and colums in an ASCII file. Within a row the values may be separated by commas, tabs, or spaces.

The first character of comment lines has to be #.

The number of rows and columns is detected by kpl.

In case of activated setting Autoplot the graphical presentation is displayed immediately according to the settings done using the dialog Configure Autoplot.

Loading of data files overwrites an eventually displayed presentation. When a data file is to be inserted in an existing graphical presentation, this has to be done by creating a new item using the Edit menu.

Save

Save As

Plot

Displays the graphical presentation or refreshes after changes.

In case of activated setting Autoplot the graphical presentation is displayed immediately after loading of plot or data files.

PostScript Output

Saves the graphical presentation as a PostScript file.

In comparison with the output obtained with Print and Print to File, these files (created with functions of the library pslib) may be edited easily. For example, the coordinates of data points are stored without scaling, according to the values from data files or function evaluations.

Print

Prints the graphical presentation to a printer chosen from a list or to a file.
