我的一个作法是，建立一个字符串数组，然后每画一道曲线，就取一个字符作为颜色。
【在 h***q 的大作中提到】
: 在一幅图里面画了很多条曲线，如何自动为他们分配颜色以示区别？

matlab by default use different colors for different lines if you
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')

我试了一下，同一幅图中最多自动支持7种不同的颜色，如果超过7条曲线，就自动重复
默认的7种颜色。这是怎么回事呢？

those are just matlab default "Lines" color map. you can define your own.
