MATLAB:在图形底部添加图例,而不更改图形宽度或调整绘图大小
我经常遇到与MATLAB绘图中的图例有关的问题,我想想出一种方法来避免在将来出现这些问题 我想做的是:MATLAB:在图形底部添加图例,而不更改图形宽度或调整绘图大小,matlab,matlab-figure,Matlab,Matlab Figure,我经常遇到与MATLAB绘图中的图例有关的问题,我想想出一种方法来避免在将来出现这些问题 我想做的是: 创建具有固定大小的地物: f=figure('Position',[0 0 800 600]) 画出我想在这个图中画的东西 x=-pi:0.01:pi 绘图(x,sin(x),x,cos(x),x,tan(x)) 将图例添加到图形底部的绘图中,而不调整绘图的大小(可以说,我可以将图形设置为“更高”,但我希望图例在绘图、轴和其他所有位置都能显示出来)。如果可能,我还希望使用包创建图例(不确定这是
f=figure('Position',[0 0 800 600]
)x=-pi:0.01:pi
绘图(x,sin(x),x,cos(x),x,tan(x))
有人知道我该怎么做吗?我使用的是倍频程,而不是MATLAB,但是下面的工作(或者至少让你更接近你想要的) 阿诺
% Create the figure and plot
f = figure('Position',[0 0 800 600]);
x = -pi:0.01:pi;
plot(x,sin(x),x,cos(x),x,tan(x));
% Set axes and figure units to pixels, get current positions
set(f,'Units','pixels')
set(gca,'Units','pixels')
fig_pos = get(f,'position');
old_ax_pos = get(gca,'position');
% Add a legend et get its position too
h = legend('L1','L2','L3','location','southoutside');
set(h,'Units','pixels')
leg_pos = get(h,'position');
% Get the new axes position, look at how much it shifted
new_ax_pos = get(gca,'position');
pixel_shift = new_ax_pos - old_ax_pos; % y position shift is positive (axes moved up), y height shift is negative (axes got smaller)
% Make figure taller and restore axes height to their initial value
set(f,'position',fig_pos - [0 0 0 pixel_shift(4)]);
set(h,'position',leg_pos)
set(gca,'position',old_ax_pos + [0 pixel_shift(2) 0 0])
% Create a new figure without legend for comparing
f2 = figure('Position',[0 0 800 600]);
x = -pi:0.01:pi;
plot(x,sin(x),x,cos(x),x,tan(x));
