The following script looks good on the screen, but the fill disappears on the
saved png.
Is this a known bug? Is there anything I can do about it?
# plot functions for numerical integration practice
function plotfuncs()
close all
plotpowerx([3,5], 'x.^5');
end
function plotpowerx(xr, ystr)
x = xr(1):(xr(2)-xr(1))/500:xr(2); # generate enough points for graph
x = [x x(end) x(1)]; # append duplicate last and first element
y = eval(ystr); # evaluate the y which will compute based on all the x
y(end-1)= 0;
y(end)=0; # last 2 values of y should be zero to complete polygon
fill(x,y);
titlestr = ['y=' ystr];
title(titlestr, 'FontSize', 20);
filename=['area' ystr(1) ystr(4) '.png'];
disp(filename);
drawnow();
saveas(gcf, filename, 'png');
end
