matlab - 如何关闭带有图形的窗口？

Question

我在matlab中有这段代码。如何关闭带有图形的窗口？我使用这个代码，但它不起作用，为什么？

plot(fig1);%Show chart
hold on;
if button == 1
    close(fig1);
    delete(fig1);
    break;
end;

好的，我更改了代码。但它不起作用。为什么？

fig1 = plot(fig0);
hold on;
if button == 1
    close(fig1);
    break;
end;

Answer 1

close command should work.

For instance:

   fig1 = figure();
   close(fig1); 

The mistake is probably somewhere else:

1. fig1 is not a figure handle.
2. button is not equal to 1

Answer 2

You're confusing plot with figure; the latter is for opening a figure, the first is to actually draw something on a figure.

fig_handle = figure;
plot(1:10);
if button==1
    close(fig_handle);
    delete(fig_handle);
    break;
end

But this is likely not going to work, it seems as you want to press a button and then close the previously opened figure. Matlab code is run sequentially, so here the variable button is immediately checked after opening the figure. I think you're looking for a function callback linked to a button.

Answer 3

You plot the data, which is in fig1. You can not close the data, you need to close the figure

f=figure;
plot(1:10); % example
close(f);

Answer 4

我想知道您是否需要在图形本身上使用属性。我以前遇到过完全相同的问题，但是您的代码看起来有点可疑。

首先，找出每个变量中的内容：

disp(class(fig1))
disp(ishandle(fig1))
disp(class(fig0))
disp(ishandle(fig0))

如果是句柄，那么据我所知fig0你不能打电话。plot(fig0)如果fig0是一组数据，那么你就是黄金。

顺便说一句，当你调用它时，调用可以由另一段代码设置close()的图形。如果所有变量都检查正常，CloseRequestFcn您可能想尝试。close force顺便说一句，我不确定所有反对票的用途，但您可能需要解释更多背景信息。这对我来说很好，但我想不是每个人都这么宽容。:-)
