那可以调整坐标轴的长度么,总觉得有点变形,和原图片的点对不上

使用plot(x,y,'*')
PLOT(X,Y,S) where S is a character string made from one element
from any or all the following 3 columns:
b blue .point - solid
g green o circle :dotted
r red x x-mark -.dashdot
c cyan + plus -- dashed
m magenta * star (none) no line
y yellow s square
k black d diamond
w white v triangle (down)
^ triangle (up)
< triangle (left)
> triangle (right)
p pentagram
h hexagram
For example,PLOT(X,Y,'c+:') plots a cyan dotted line with a plus
at each data point; PLOT(X,Y,'bd') plots blue diamond at each data
point but does not draw any line.
祝你学习愉快!
