我如何指定绘图应移至哪个图形? [英] How can I specify to which figure a plot should go?

问题描述

我打开了多个图形，我想在运行时独立更新它们.以下玩具示例应阐明我的意图:

I have multiple figures open, and I want to update them independently during runtime. The following toy example should clarify my intention:

clf;

figure('name', 'a and b'); % a and b should be plotted to this window
hold on;
ylim([-100, 100]);

figure('name', 'c'); % only c should be plotted to this window

a = 0;
b = [];
for i = 1:100
    a = a + 1;
    b = [b, -i];
    c = b;
    xlim([0, i]);
    plot(i, a, 'o');
    plot(i, b(i), '.r');
    drawnow;
end

这里的问题是，当我打开第二个figure时，我无法告诉plot函数将其绘制到第一个，而不是第二个(并且仅c应该绘制到第二个). /p>

The problem here is that when I open the second figure, I cannot tell the plot functions to plot to the first one instead of the second (and only c should be plotted to the second).

推荐答案

您可以使用

figure(1)
plot(x,y) % this will go on figure 1

figure(2)
plot(z,w) % this will go on another figure

该命令还将使图形可见并位于所有内容的顶部.

The command will also set the figure visible and on top of everything.

您可以根据需要通过发出相同的figure命令在图之间来回切换.另外，您也可以使用图形的手柄:

You can switch back and forth between the figures as necessary by issuing the same figure command. Alternatively, you can use the handle to the figure as well:

h=figure(...)

，然后发出figure(h)而不是使用数字索引.使用此语法，您还可以通过使用

and then issue figure(h) instead of using numeric indices. With this syntax, you can also prevent the figure from popping up on top by using

set(0,'CurrentFigure',h)
