Hi all! I'm trying to plot a curve with filledcurves gnuplot option, but without any success. What i've tried: set_plot_options([gnuplot_curve_styles,["with filledcurves closed"]]); plot2d(sin(x),[x,0,2*%pi]); but what i get it's not different from the usual sin(x) plot. What i'm doing wrong? thanks, Giovanni
