Draw a Plot in C with GNU plotutils

Install plotutils Debian $ sudo apt-get install plotutils-dev Fedora $ sudo dnf install plotutils-devel Use PlotUtils to plot a graph Let us draw the $sin(x)$ function using math library. #include <stdio.h> #include <math.h> #define RANGE 100 // Export data to stdout void plot(double *x, double *y, size_t len) { for (unsigned int i = 0; i < len; i++) printf("%lf %lf\n", x[i], y[i]); } int main(void) { int i; double x[RANGE], y[RANGE]; // Compute sin(x) for (i = 0; i < RANGE; i++) { x[i] = i * 0.
