plt hide axis ticks

To hide axis ticks in a C plot, you can use the axis() function with the ticks parameter set to 0. Here's an example:

#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include <string.h>
#include "gnuplot_i.h"

int main()
{
    gnuplot_ctrl *h;
    h = gnuplot_init();

    gnuplot_cmd(h, "set xtics 0");
    gnuplot_cmd(h, "set ytics 0");
    gnuplot_cmd(h, "set border 0");

    double x[] = {0, 1, 2, 3, 4, 5};
    double y[] = {0, 1, 2, 3, 4, 5};

    gnuplot_plot_xy(h, x, y, 6, "Plot");

    gnuplot_close(h);

    return 0;
}

This code initializes a gnuplot control structure, sets the x and y ticks to 0, sets the border to 0 to hide the axis lines, and plots a simple XY graph with some data points.
