From Qt Apps:

Version 0.9.7.2 of QtiPlot, a data analysis and scientific plotting application, has been released. Changes:

• Implemented the possibility to configure the behavior of note editors with respect to fonts and TAB length.
• Improved autocompletion in note windows.
• Improved Python scripting support:
• added support for rectangles and ellipses on 2D plots.
• added the possibility to customize plot curves in terms of color, line width and line style.

• added a launch option (-X) allowing to execute scripts without displaying the user interface.
• Improved export to vector formats with custom resolution.
• Improved Tex equation editor dialog.
• Improved the import of Origin 7.5 project files.
