Question

如何仅将MATLAB GUI创建的绘图打印到PDF文档中？

我知道在线提供的名为export_fig的功能，但我们不允许使用外部编码工具。

我目前有以下

function PrintButton_Callback(hObject, eventdata, handles)
set(gcf,'PaperType','A4','PaperOrientation','landscape','PaperPositionMode','auto');
print(get(handles.Axes,'Parent'), '-dpdf','Results.pdf');

然而，这导致我的整个GUI图形被保存。如何仅选择轴（“轴”）的绘图？

Answer 1

print命令仅接受figure作为handle参数...

要打印指定的轴，只有一个技巧是使用copyobj将此轴复制到新的临时图形，并在新图形上使用print命令。

以下是一些示例代码：

%% -- Test code
function [] = TestPrint()
%[
    % Create figure with two axes
    fig = figure(1); clf;
    ax1 = subplot(1,2,1);
    plot(rand(1, 12));    
    ax2 = subplot(1,2,2);
    plot(rand(1, 12)); 

    % Print the whole figure
    print(fig, '-dpdf', 'figure.pdf');

    % Print ONLY second axis
    printAxis(ax2, '-dpdf', 'axis.pdf');
%]
end

%% --- Print specified axis only
% NB: Accept same arguments as 'print' except for first one which now is an axis.
function [] = printAxis(ax, varargin)
%[
    % Create a temporary figure
    visibility = 'on'; % You can set it to off if you want
    tempFigure = figure('Visible', visibility);
    cuo = onCleanup(@()clearTempFigure(tempFigure)); % Just to be sure to destroy the figure

    % Copy selected axis to the temporary figure
    newAx = copyobj(ax, tempFigure);

    % Make it fill whole figure space
    set(newAx, 'OuterPosition', [0 0 1 1]);

    % Print temporary figure
    print(tempFigure, varargin{1:end});        
%]
end
function [] = clearTempFigure(h)
%[
    if (ishandle(h)), delete(h); end
%]
end

Answer 2

打印前禁用轴可见性：set(gca,'Visible','off')。

仅在MATLAB GUI上打印
