When starting QtiPlot from the command prompt, you can supply the name of a project file:
Other file formats are also accepted: .opj, .ogm, .ogw, .ogg for Origin projects, .qti, qti.gz for QtiPlot projects, .xls, .xlsx for Excel workbooks, .ods, .fods for Open Document Format Spreadsheets, .mat for Matlab files, .tdms for LabVIEW TDM Streaming (TDMS) file format, .db, .dbf, .mdb, .accdb for dBase, MySQL, SQLite and Microsoft Access databases and all the image file formats (raster or vectorial) that can be read by QtiPlot.
The name can also refer to an ASCII file:
In this latter case, a new "untitled" project will be created, containing a table or matrix with the ASCII data from the file. The file is read and interpreted using the current settings from the Import -> Import ASCII... command dialog.
Valid options are:
-a or --about: show about dialog and exit
-c or --console: show standalone scripting window
-d or --default-settings: start QtiPlot with the default settings
-h or --help: show command line options
-l=XX or --lang=XX: start QtiPlot in language XX ('en', 'fr', 'de', ...)
-m or --manual: show QtiPlot manual in a standalone window
-v or --version: print QtiPlot version and release date
-x or --execute: execute the script file given as argument
-X: execute the script file given as argument without displaying the user interface. Warning: 2D plots are not correctly handled in this mode!
