An Arduino library for easy graphing on host computer via serial communication
by: Devin Conley
- 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
#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() }
