Compare (show numeric difference) two channels

[y2old]

Hasan, It would be a wonderful feature if could subtract one channel from another channel to see in real time. I modified serialplot AsciiReader::parseline samples array after for loop for a quick demonstration by simply channel 1 = channel 1 minus channel 2 (samples->data . . .) so now channel 1 shows the difference. I can't get serialplot project to compile as I'm not that good at modern build tools. Would you be willing to do the code mod and create a windows EXE so I can try it out and email me the EXE. My serial input stream is ASCII float values so just the ASCII mod and I always have at least 2 channels incoming so do not need any fault checking. Thank you
