使轴不可见或完全删除绘图 [英] make axes invisible or delete plot completely

问题描述

我有一个matlab gui，其中应包含4个地块.如果在列表中选择了其他文件，则应更新第一幅图.其他3个仅应要求可见(并计算).

I have a matlab gui that shall contain 4 plots. The first plot shall be updated if a different file is selected in a list. the other 3 shall only be visible (and be calculated) on request.

但是，一旦绘制了2-4个图，我就无法使它不可见.

However I fail to make plots 2-4 invisible after they have been plotted once.

我尝试了

set(handles.axesImage, 'Visible', 'off');

但这只会删除轴，不会删除整个图.

but that only deletes the axis, not the whole plot.

除了使事物不可见之外，还可以实际删除内容吗?通常，我会打电话给close(hfig);，但是在这里我没有数字.

Instead of making things unvisible, is it also possible to actually delele the content? Typically I would call close(hfig);, but here i have no figure.

我尝试了

handles2hide = [axisObj;cell2mat(get(axisObj,'Children'))]; 
delete(handles2hide);

但是对于未绘制的轴(启动后)，该操作将失败

But that fails for the unplotted axes (after startup)

我将代码更改为:

axisObj = handles.axesContour;
if ishandle(axisObj)
    handles2delete = get(axisObj,'Children');
    delete(handles2delete);
    set(axisObj,'visible','off') 
end
if (isfield(handles,'contour') && isfield(handles.contour,'hColorbar'))
    delete(handles.contour.hColorbar);
    delete(handles.contour.hColorbarLabel);
end

但是，颜色栏仍保持未删除状态，并且handles.contour.hColorbar失败，并显示Invalid handle object.

However the colorbar remains undeleted and handles.contour.hColorbar fails with Invalid handle object.

推荐答案

我现在用

function z_removePlots(handles)

if (isfield(handles,'image') && isfield(handles.image,'hplot'))
    if ishandle(handles.image.hplot)
        delete(handles.image.hplot);
        delete(findall(gcf,'tag','Colorbar'));
        handles.image.hplot = 0;
        set(handles.axesImage, 'Visible', 'off');
    end
end
if (isfield(handles,'contour') && isfield(handles.contour,'hplot'))
    if ishandle(handles.contour.hplot)
        delete(handles.contour.hplot);
        handles.contour.hplot = 0;
        ClearLinesFromAxes(handles.axesContour)
        set(handles.axesContour, 'Visible', 'off');
    end
end
guidata(handles.output,handles);

与

function ClearLinesFromAxes(axisObj)
if ishandle(axisObj)
    handles2delete = get(axisObj,'Children');
    delete(handles2delete);
end
