-You can modify the code to dynamically refresh the graph with something like:
-
-```c++
-...
-//We display 100 times the graph with the sinusoid shifted each time
-for(shift =0;  shift <100; shift ++){
-   // We set a sinusoid in the vector (converting [-1f, 1f] -> [0, 255]) and we  shift it
-   for(i=0; i!=vector.size; i++) vector.uchars[i]=128+127*sinf(i/2.f+ shift);
-   //If it is not the first time we erase the previous graph by putting back (ANSI escape code) the cursor 16 lines (height of the graph) up. 'sprint' stand for fprint on stderr
-   if (shift != 0) blc_eprint_cursor_up(16); //blc_text.h function
-   /*We graph the vector, with title "vector test", the height of 16 chars, the limit max 256 and limit min 0.
-   Text on abscissa "position" and text on ordinate "intensity"*/
-   vector.fprint_graph_uchars(stderr, "Vector test", 16, 256, 0, "position", "intensity");
-   //We stop 100ms to let time to the user to see the graph.
