Graph Capture

The software was designed for suitable chart creation. From text files or programs, that haven't visual charts themselves, data is passed to "Graph Capture" and plotted there. But you have to write Perl RegEx expressions to extract X and Y-values from raw data. Otherwise, you can request suitable filter templates here https://www.facebook.com/vlad.dubov.77. For making RegEx expressions short docs are also included in the program. You can find "Help: regular expressions in Perl" in the installation folder or in the program's top bar. The program can plot charts from a static file ( just drag and drop the file) or from a dynamically written file - by using a plugin that "connects" to the source. Win 32/64 7/8/10/11 and probably XP ;)
