• This is in regards the Devin Conley Plotter library, available on github
  Note: Arduino has a built-in serial plotter as well. This is not that.
        but if interested, see: (link to:) arduino.cc Serial plotter tutorial

  --------------------------------------

• download/install the plotter library
• download listener app.
  mine is: arduino-plotter-listener-linux64.zip
  extracted folder contains the executable file: listener
• sketch:
  • #include "Plotter.h"
  • globals:
    Any variable that you want to plot must be declared as a global variable.
    Plotter p; // starts the plotter instance
  • setup:
    p.Begin(); // start plotter
    p.AddTimeGraph( "Some title of a graph", 500, "label for x", x ); // x is the variable that will be plotted
    multiple variables can be plotted:
    AddTimeGraph([graph title in quotes], [not sure what this number is... # of points plotted?], [label for firstVar, in quotes], [firstVarName], [label for secondVar, in quotes], [secondVarName], ..., [label for nth var, in quotes], [nthVarName] );
  • loop:
    update your plotted variable as desired ...
    p.Plot(); // do the plot
• upload your sketch. when done and running,
  execute the listener app
  If the listener doesn't find your port, ie. keeps scrolling it's search through available ports, ...
  then there probably is some other user on the serial port.
  close listener, close any other sketches, remove all serial.print statements from your sketch,
  re-select port, re-upload sketch, restart listener
