I am using the arduino due to read analogue in voltages. The Ide is version 1.6.9 I can see the voltage values displayed on the serial monitor. However when I select the serial plotter half of the time nothing comes up on the monitor. When I switch back to serial monitor I get an error message saying the serial monitor cannot be opened while the serial plotter is open.
This also happens with the arduino uno.
Has anyone else seen this problem?
