From the developer:
The goal of PublishPlot is to quickly create publication quality plots from any text-based table of data. It is developed by a professor and editor for an international journal who wanted to create good plots and was tired of rejecting papers that had ugly plots (especially standard plots created by Microsoft Excel). PublishPlot is ideal for students, teachers, professors, scientists, and engineers.
