GNUplot pipe inerface to plot armadillo matrix

Show all headers | View raw

Dear All,

I am able to plot data using C++ program utilizing pipe. However I am unable to plot armadillo matrix using pipe (minimal interface)?

Currently I am using following code to plot data from egg.dat file (contain data in matrix format)

gnuplot p;

p("set terminal pngcairo  transparent enhanced font \"arial,20\" fontscale 1.2 size 1000, 700 ");
p("set output \'result.png\'");
p("set xlabel'Time(sec)'");
p("set ylabel'Amplitude (V)'");
p("set style data lines");

p("plot \'egg.dat\' using 1:6 title\'Clock-6\'lt rgb 'blue' lw 2.5,\
  \'egg.dat\' using 1:7 title\'Clock-7\'lt rgb 'red' lw 2.5");

return 0;

Now instead of data from egg.dat, I wish to plot armadillo matrix A. Anyone have any experience?

Thank you.
