KMatplot下载: 功能类似于Origin

KMatplot is a gnuplot-like tool for plotting data sets in either two or three dimensions. It can plot many types of 2d plots, including pixmaps and contours, and 3d surfaces. It offers a full WYSIWYG mode with multiple objects on a single page. See the screenshot section for more details.

As opposite to Gnuplot, KMatplot is very clickable, so easier to use for unexperienced users. It can be used instead of Gnuplot with Octave and Scilab - there are new dll functions installed in those packages, which communicate with KMatplot through an Unix socket. Those functions are named 'kplot', 'kimage', kmesh', ... and are similar to those found in Octave by default.
