I’m working on a project where I want to display a graph along with some comments, not just labels but actual sentences. I know I can’t open the serial monitor and plotter at the same time, but is there another way to accomplish this? I’m using Arduino 1.8.13 and the Arduino Uno Board. Thank you in advance for any help!
You could do this with an LCD, no problem. Just use part of the display for a graph and the rest for data. Your only problem may be Uno's ability to drive it but, if the display is I2C or serial, that is probably OK. It depends on what else you are doing.
If you mean you want to display the graph on a P.C. you could use Processing to receive data from the Arduino and display the graph/text etc.
see here for a demo of how you can receive the data in Processing: GitHub - alanesq/processing-arduino-starting-point: processing/arduino starting point sketch
and great examples of using Processing here: https://thecodingtrain.com/
BTW - Processing will no doubt have libraries available for creating graphs
