GP is aimed to be simple and fast tool to analyse numerical data. It does not claim to replace all other plotters.
- Plot 2D figures with lines or dots from plain text or binary files.
- Spatial structure based rendering to look through a large datasets.
- Multiple axes are supported by design.
- Real-time plotting from multiple asynchronous sources.
- Simple math operations like subtraction or polynomial fitting.
- Data pick tool to extract accurate numeric values.
- Static (from file) and dynamic (from UI) configuration.
- Export screen or data to the file (PNG, SVG, CSV).
The main platforms are GNU/Linux and Windows. GP can be embedded to any third-party SDL2 based application.
Here are the dependencies that you need to have prior to compile.
To compile GP you could use Makefile from source directory.
You can just use GP with a plain text files or CSV tables.
$ gp file1.txt file2.csv ...
Note that first valid line of plain text (or CSV) file will be interpreted as description of the columns. Here is a simple example of the plain text file.
$ cat file1.txt
time@sec var1@A var2@V hexpar@ ...
0.1 0.0 0.0 0x0001
0.2 1.1 2.1 0x0035
0.3 1.5 3.4 0x0d1f
0.4 1.7 4.1 0x0e00
...
You also can open a multiple files from UI to combine various columns from different files in a single plot. Also check for command line options help.
$ gp -h
Take a look into configuration examples that describes most of the options.
You can make real-time plot from raw serial device or from growing logfile.
- Improve embedded API.
- Add a dependency based subtract calculation.
- Optimize line drawing performance even more.
