When starting kpl from the command prompt, you can supply the names of one or more plot or data files (either local filenames or URLs):
kpl [filenames ...]
In case of activated setting Autoplot, the graphical presentation
is displayed immediately.
When in addition Autofit is activated, in case of a data file also a parameter fit to a function is automatically performed and the function is displayed, too.
kpl can be started to display a plot file by clicking its symbol in a KFM window or by selecting this action from its context menu.
kpl supports the Drag and Drop protocols of KDE and Qt . This means that you can open one or more plot or data files by dragging their symbols onto the kpl window. Data files will be recognized by the extension .dat, plot files by the extension .plo. In addition to local files also URLs may be passed in this way.
kpl supports the following shortcuts:
Ctrl + N Open a new plot file.
Ctrl + O Open an existing plot file.
Ctrl + S Save the current plot file.
Ctrl + W Close the current plot file.
Ctrl + P Print the graphical presentation.
Ctrl + Q Quit kpl.
