Grace (originally named Xmgrace) is a 2D plotting tool which allows you to interactively modify plots, to set all kind of plot parameters, change the appearance of your figure, and to save the figure in the format of your choice. It can also be scripted to automate the generation of plot images. Grace also includes many tools for data set analysis, including regression fitting, plotting of functions and data set manipulations.
