RtPlot is a small program for displaying 2D plots in real time.
It consumes little resources. It was written because of the need to monitor the progress of computationally intensive scientific programs which run for a long time and occasionally produce output suitable for plotting. The user can open as many windows as needed for plotting. Each window can monitor several data files and plot their contents. When a data file is updated by another concurrently running program, its plot is automatically updated as well. It is also possible to view in a window several recent updates to a data file. The user can configure the frequency in which RtPlot checks for file updates, stop or renew the updating of plots, the range of x & y columns, number of ticks along axes and other parameters. Configurations can be made with the mouse, command line or XML configuration files. Each plot can be printed or saved in BMP/PNG formats either manually or when the display is updated.
