Xmgrace or Grace, is a program for plotting graphs, with a clickable GUI to set graph properties. It is a WYSIWYG(what you see is what you get) 2D plotting tool. The program is free to download, install and use. The program supports, interactive plotting to generate, 2D graphs, bar charts and execute data fitting routines. Multiple graphs can be plotted on the same canvas. Various symbols styles and formatting options can be included in the plots. Grace is one of the best liked plotting software in scientific community. QtGrace fork, provides a binary for Windows OS using Qt-SDK tool. Back-end plotting of many popular scientific and engineering software use Grace. More details are available on this website: http://plasma-gate.weizmann.ac.il/Grace/ .
