jag - just a grapher

Jag is a simple plotting application which was created for telemetry data analyzing and simple plot creation. Jag is based on QCustomPlot v.1.3.2 (http://www.qcustomplot.com/ ). Some features were not implemented on purpose to keep jag as simple as possible. As a result jag can't plot surfaces, graphs in polar coordinates, financial plots, bar plots etc. At the moment jag supports CSV format and data in table format (see examples in "tlmExamples" directory).

See the project page for more information.

Features

  1. Arbitrary layout. You can easily change the number of graphs and axes, move graphs from one axes box to another, change axes boxes location.
  2. Comprehensive dialog to choose parameters from data sources (particularly useful if you have dozens or hundreds of parameters in each data source).
  3. Built-in secondary processing which allows you easily perform basic mathematical computations on your data (library of available functions is not very huge at the moment (about 40 functions) but in future it will be significantly expanded). Of course basic mathematical operators (+,-,*,/,^) are available.
  4. All usual means to change graph properties, convert plots to images, preferences to customize JaG appearance and behavior, shortcuts for all essential actions.

Building

To build jag you will need:

  1. Boost 1.58
  2. QSint 0.2.2

Platforms

Jag is based on Boost, Qt and libraries based on Qt. Hence in theory jag is a cross-platform application.

Languages

At the moment JaG GUI supports English and Russian languages.

Plugins

You can extend the number of supported data formats with plugins. See API in src/plugins/plugins_api.h. See a simple dummy example of such plugin in pluginExample directory.
