XY PLOT ENGINE

Installation

git clone https://github.com/Bilodev/XYPlotEngine
cd XYPlotEngine
make && ./main.exe

Use

#include "Engine/Engine.h"

Define your functions and costants $\newline$

Note that the "NAN" is used as domain defintion, in this case the function "costant" is only defined for $x <20 \lor x > 30$

#define M_PI 3.14159265358979323846

double f(double x) { return x * x; }
double constant(double x){
    if (20 < x && x < 30) return NAN;
    return 1;
}

Feed your functions to the engine

int main()
{
    int error;

    engine_setname("My Loved Functions");

    error = engine_feed_function("square", f);
    if (error) {
        printf("%s", engine_get_error());
        return 1;
    }
    engine_feed_point("P", 2, 2);
    engine_feed_point("A", 3, 3);
    engine_feed_point("Q", 2, -3);

    engine_feed_function("exp", exp);

    engine_draw();
    return 0;
}
