RLPlot is an open source graphical user interface based program for displaying scientific data in standard formats. It has full support for all error-bar types and it has greater flexibility with displaying colour and texture in charts than gnuplot (filled bar chart boxes are possible without any additional programs).
You may copy data from another spreadsheet program pasting them into RLPlot. It uses a common parser for spreadsheet cells, function plotting and curve fitting.
Output is generated on the X display where further changes can be made to the graph using point and click methods. Images can be exported as scalable vector graphics (SVG) as well as EPS, WMF and TIFF formats.
Key Features
- Basic statistics.
- Interactive graphical user interface.
- Vector fill patterns.
- Virtually unlimited data (hardware dependent).
- Exports SVG, EPS and several bitmap formats including PNG and JPG.
- Uses only ASCII files which may be created or modified by scripting languages.
- Uses a common parser for spreadsheet cells, function plotting and curve fitting.
- Supports a “C”-style scripting language with all elements of the scripts being inside the spreadsheet.
- Cross-platform support – available for Linux and Windows,.

Exprlp is a console application which reads RLPlot *.rlp files and converts them to other vector formats. The major objective for using exprlp is server sided scripting.

RLPlot is written in C++. Learn C++ with our recommended free books and free tutorials.
