hello all,
my data keeps changing as i iterate over many. till now i used to
generate a data file to dump the data pertaining to each iteration or
to dump all the data in to a single file separated by two blank lines
and then use the ``index" feature of gnuplot.

i want to be able to plot my data after each iteration without having
to generate data files. assuming a c/c++ code i want something of the
following:

int i;
double x[10];
double y[10];
for(i = 0; i < 10; ++i)
{
 generate_x_values(x);
 calculate_y_values(y, x);

 plot(x, y, "format string");

 pause();
}

any advice or recommedation is welcome.
