h = subplot( 2, 2, 1)% 先让MATLAB默 认绘制第1幅子图,h是子图1的句柄
po = get( h, 'Position' ) % get命令从句柄h中获取'Position'的内容,返回一个含4个元素的一维数组放到po中。这4个元 素分别是子图1的left, bottom, width, height。
subplot( 'Position', [po(1)+0.03, po(2)-0.03, po(3), po(4)]) 子图1的新位置可以这样调整

set( gca, 'XTick', [1:12] ) gca表示当前对象句柄,set命令分别对当前对象(即子图1)设置坐标轴XTick和YTick属性。这 两个属性分别表示了坐标轴的实际绘值范围。

plot( 1:12, bc, '-r.', 'MarkerSize', 10 ) 子图1中第1条曲线用实线绘,带有圆点,红色。MarkerSize属性设 置圆点的大小是10。这样画出来的就是实心圆了。

我将legend放在了子图4上。
gca=legend( 'BC', 'Nitrate', 'Sulfate', 'POA', 'SOA', 4 ) 4表示把legend放在子图的右下角,还有几个数字的含义是:
0 = Automatic "best" placement (least conflict with data)
1 = Upper right-hand corner (default)
2 = Upper left-hand corner
3 = Lower left-hand corner
4 = Lower right-hand corner
-1 = To the right of the plot
po=get( gca, 'Position' )发现这样放置后legend要挡住图,因此需要再微调一下。获得legend的'Position'值。
set( gca, 'FontSize', 8, 'Position', [po(1)-0.01, po(2)+0.01, po(3), po(4)] )重新设置legend的位置,同时设置legend里面的字体为8号。
legend('boxoff') 不画legend的外框。
强调的是上述调整legend的值要不断地试。因为legend相对子图的位置还要随画图窗口大小变 化而变化。如果你看不懂这句,试试就知道了。
我一般是将MATLAB画出的图打印成PDF,再用Acrobat打开截屏,贴到WORD中,这样图 像质量似乎比较好。谁还有更好的将MATLAB图转贴到WORD的方法,欢迎赐教。
鼠标右键设置。右击legend(你所谓的方框),选择update刷新。或者删了,右击图片框,选择legend图标说明,重新创建一个legend。通过菜单命令也可实现。
