问题描述
我对MATLAB并不是特别有经验，所以这可能是一个愚蠢的问题，但我将不胜感激.
I am not especially experienced with MATLAB so this might be a dumb question, but I would appreciate any help that can be given.
我有一些代码可以创建一些轴，将uicontextmenu分配给所述轴，然后在轴上绘制用户选择的图形.在每种绘图情况下，都需要右键单击图形(应如此)来访问uicontextmenu，它需要除pcolor和Contourf外.为什么会这样呢?我有什么办法可以解决这个问题?
I have some code that creates some axes, assigns a uicontextmenu to said axes, and then plots a graph of the user's choosing on the axes. The uicontextmenu is accessible by right-clicking on the graphs (as it should be) in every plot case it needs to EXCEPT for pcolor and contourf. Why would this be? Is there any way I can get around this?
通过广泛的调试，我发现uicontextmenu可以访问，直到调用了pcolor(或contourf)函数，然后它消失了.我想念什么?
Through extensive debugging I have found that the uicontextmenu is accessible until the pcolor (or contourf) functions are called and then it disappears. What am I missing?
编辑:根据要求，提供以下示例代码.如果使用pcolor，则不会显示uicontextmenu，如果使用plot，它将显示.我认为这与光标突出显示的数据有关.如果用鼠标右键单击绘制的数据，则两者均不显示任何内容.但是为什么呢?
As requested, example code below. If you use pcolor the uicontextmenu won't appear and if you use plot then it will. I think it has something to do with the data the cursor is highlighting. If your cursor right clicks on plotted data, nothing appears in both. But why is this?
axes;
stuff = uicontextmenu('Parent',ancestor(axes,'figure'));
stuffm = uimenu('Parent',stuff,'Label','Change something');
set(axes,'uicontextmenu',stuff);
x = randn(10);
y1=randn(10,1);
y2=randn(10,1);
plot(y1,y2)
%pcolor(x)
推荐答案
pcolor函数创建一个具有自己的uicontextmenu属性的surface图形对象.您必须在pcolor返回表面手柄之后进行设置:
The pcolor function creates a surface graphics object which has its own uicontextmenu property. You have to set it after the pcolor returns the surface handle:
h= pcolor(x);
set(h,'uicontextmenu',stuff);
这篇关于使用pcolor和Contourf时无法访问uicontextmenu(MATLAB R2014b)的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
