您可以拥有 PLOT 自动为您选择线条颜色.如果所有6个向量的长度都相同，则可以将x和y坐标放入N×6矩阵X和Y中，并将它们传递给

You can have PLOT automatically choose line colors for you. If all 6 of your vectors are the same length, you can put the x and y coordinates into N-by-6 matrices X and Y and pass these to PLOT. A different color will be used for each column:

plot(X,Y,'-s');  %# Plots lines with square markers

您还可以使用一些内置的颜色图来生成一组颜色，然后在分别绘制每条线时使用这些颜色.例如:

You could also use some of the built-in colormaps to generate a set of colors, then use these when you plot each line separately. For example:

cmap = hsv(6);  %# Creates a 6-by-3 set of colors from the HSV colormap
for i = 1:6     %# Loop 6 times
  plot(X(:,i),Y(:,i),'-s','Color',cmap(i,:));  %# Plot each column with a
                                               %#   different color
end
