SciDAVis is a free interactive application aimed at data analysis andpublication-quality plotting. It combines a shallow learning curve andan intuitive, easy-to-use graphical user interface with powerfulfeatures such as scriptability and extensibility. SciDAVis runs onGNU/Linux, Windows and MacOS X; possibly also on other platforms like*BSD, although this is untested.
SciDAVis is similar in its field of application to proprietary Windowsapplications like Origin andSigmaPlot as well as free applicationslike QtiPlot, Labplot andGnuplot.

免费开源的自由软件SciDAVis，主要用作数据分析和刊物（论文）中图表的生成。简单易用，支持各主流操作系统平台windows,linux,mac os x。
因为有图形界面比gnuplot要方便。而且可以很方便的输出各种格式包括pdf的文件。
