Serial Plotter Plotting Bug

When plotting using Serial.println and then pausing the Serial.println (just like a one time trigger), and then resetting the arduino to perform it again, the old serial plotted point is not erased and remains static in the plot window.


Start by reproducing the issue in the Arduino IDE 1.x Serial Plotter: send values with Serial.println, pause output, reset the Arduino, and observe the plot window. Trace the Serial Plotter entry point and related rendering or reset handling. Done means the old plotted point is removed when the Arduino is reset and the sequence is repeated.
