%% Automatically Calculate Margin to Include Title and Labels % Copyright 2015 The MathWorks, Inc. %% Can't embed yet % Automatically calculate a margin around the axes so that the captured % image data includes the title, axis labels, and tick labels. % % Create a plot with a title and an _x_-axis label. plot(rand(5)) xlabel('x values') title('Plot of Random Data') %% % Change the axes units to pixels and store the |Position| and |TightInset| % property values for the axes. The |TighInset| property is a % four-element vector that contains the margins used around the axes for % the tick values and text labels. ax = gca; ax.Units = 'pixels'; pos = ax.Position; ti = ax.TightInset; %% % Create a four-element vector, |rect|, that defines a rectangular area % covering the axes plus the automatically calculated margin. The first two % elements of |rect| specify the lower-left corner of the rectangle % relative to the lower-left corner of the axes. The last two elements of % |rect| specify the width and height of the rectangle. rect = [-ti(1), -ti(2), pos(3)+ti(1)+ti(3), pos(4)+ti(2)+ti(4)]; F = getframe(ax,rect); %% % Use |imshow| to display the captured image data. %% Embed this section figure imshow(F.cdata)
