April 3, 2012 gnuplot 4.2 and Windows XP and Vista are being used. Question: Can anyone supply code for storing the plot displayed on the screen as some type of picture file or other type of file, and then immediately reloading that file for use as the background for a new plot? I know how to generate png files etc. that contain the screen data. But I don't know if those types of files can be reloaded. Plots with information from so many different files are being generated that it appears that the plot command is eventually simply running out of steam. And error messages are being generated. The only way that I can think of to deal with that problem is to generate a plot, save it as a picture file or some other type of file, reload it as the background file, and then plot more data on top of that background. What would be the simplest way to do that? Or, is there a better way to deal with that plot command limitation? Information from various files cannot be merged into a smaller number of files as the various types of data are so different from one another. They include shapes, lines, and text having a wide range of sizes and colors. This is part of an effort to develop a potentially important freeware download research computer program for use by the international scientific community. Several computer programmers and programs written using a number of different computer languages are involved with the data generation process. A Perl language program is coordinating the activities of the various computer programs. gnuplot is being used for the final display.
