星座图怎么绘制？
这个程序是绘制星图的：按下鼠标左键开始绘制一个星座图，点击右键结束当前星座
function xingzuo
figure('WindowButtonDownFcn',@wbdcb)
ah = axes('DrawMode','fast');
axis ([1 10 1 10])
title('绘制星座图')
color1='brcmkgy';
num=1;
function wbdcb(src,evnt)
if strcmp(get(src,'SelectionType'),'normal')
set(src,'pointer','circle')
cp = get(ah,'CurrentPoint');
xinit = cp(1,1);yinit = cp(1,2);
hl = line('XData',xinit,'YData',yinit,...
'Marker','p','color',color1(num));
set(src,'WindowButtonMotionFcn',@wbmcb)
set(src,'WindowButtonUpFcn',@wbucb)
end
function wbmcb(src,evnt)
cp = get(ah,'CurrentPoint');
xdat = [xinit,cp(1,1)];
ydat = [yinit,cp(1,2)];
set(hl,'XData',xdat,'YData',ydat);drawnow
end
function wbucb(src,evnt)
if strcmp(get(src,'SelectionType'),'alt')
num=num+1;
if num>7
num=1;
end
set(src,'Pointer','arrow')
set(src,'WindowButtonMotionFcn','')
set(src,'WindowButtonUpFcn','')
