arduino-plotter

Plotter is an Arduino library for easy graphing on host computer via serial communication

---

Features:

• Continuous multi-variable plots against time
• 2-variable "x" vs "y" plots
• Display multiple graphs within single resizable window
• Support for any data type that can be cast to a double
• Simply pass a reference to your variables when the graph is added, no need to update each value explicitly
• Control number of data points displayed on each graph
• Auto-scaling to fit all data on graph
• Configurable line color per variable
• Stand-alone listener application, written with Processing, is provided

---

Extremely easy usage:

#include "Plotter.h"

double x; // global variables
Plotter p; // create plotter

void setup()
{
  p.Begin(); // start plotter
  
  p.AddTimeGraph( "Some title of a graph", 1500, "label for x", x ); // add any graphs you want
}

void loop()
{
  x = 10*sin( 2.0*PI*( millis() / 5000.0 ) ); // update your variables like usual

  p.Plot(); // plot all current data -- usually called within loop()
}
