plot them in one plot function.
if you want to use your own colors, you can define a color matrix (Nx3)
in rgb colors. each time take a row from that matrix and plot using that
color by plot(x, y, 'Color', colors(ii,:)).
you can also get the default line colors used by matlab by
colors = colormap('Lines')

默认的7种颜色。这是怎么回事呢？
