MATLAB:保存为无花果后，plotlyy中的框未对齐 [英] MATLAB: misaligned boxes in plotyy after saving as fig

问题描述

我使用plotyy在一张图中放置两个图:

I use plotyy to put two plots in one graph:

f = figure('Color','white');
[ax,p1,p2] = plotyy(xx, yy1, xx, yy2);
ylabel(ax(1),'Phase','FontSize',18);
ylabel(ax(2),'Spectrum','FontSize',18);
set(ax,{'ycolor'},{'k';'k'});
set(p1,'LineWidth',2,'Color',[0.4940,0.1840,0.5560]);
set(p2,'LineWidth',2,'Color','red');
xlabel(ax(1),['Frequency [THz]'],'FontSize',18);
set(ax,'FontSize',14)

图形显示得很完美，但是当我尝试将其保存为无花果时，会出现诸如未对齐框之类的东西.

Figure is displayed perfectly, but when I try to save it as fig something like misaligned boxes appears.

我尝试使用链接轴，但没有结果.

I tried to use linkaxes, but with no result.

推荐答案

一直是我最喜欢讨厌的MATLAB函数之一.这是一个非常有用的功能，我似乎总是会遇到一些错误，以至于我完全停止使用它，而只希望堆叠两个(或更多)轴对象并分别绘制它们.然后，您可以将子"轴的Position属性设置为与主轴相同，它们可以很好地堆叠.

plotyy has been one of my favorite MATLAB functions to love to hate. It's a really useful function that I always seem to run into bugs with, to the point where I've completely stopped using it in favor of just stacking two (or more) axes objects and plotting to them separately. You can then set the Position property of the 'sub' axes to the same as your primary axes and they will stack nicely.

一个功能示例:

xx = linspace(-15,15,100);
yy1 = sin(xx);
yy2 = cos(xx);
f = figure('Color','white');

ax(1) = axes('Parent', f);
ax(2) = axes('Parent', f, 'Color', 'none', 'XTick', [], 'YAxisLocation', 'right');

p1 = plot(ax(1), xx, yy1);
hold(ax(2), 'on'); % Hold to preserve our axes properties set above
p2 = plot(ax(2), xx, yy2);
hold(ax(2), 'off');

ylabel(ax(1),'Phase','FontSize',18);
ylabel(ax(2),'Spectrum','FontSize',18);
set(ax,{'ycolor'},{'k';'k'});
set(p1,'LineWidth',2,'Color',[0.4940,0.1840,0.5560]);
set(p2,'LineWidth',2,'Color','red');
xlabel(ax(1),'Frequency [THz]','FontSize',18);
set(ax,'FontSize',14)

set(ax, 'ActivePositionProperty', 'position'); % Resize based on position rather than outerposition
set(ax(2), 'Position', get(ax(1), 'Position')); % Set last to account for any annotation changes

在堆叠轴的同时，您还将注意到我将ActivePositionProperty设置为position(而不是outerposition).当Units属性为时， MATLAB自动调整轴大小.设置为Normalized，这似乎是问题出现的主要地点.在调整大小时，MATLAB还会修改第二个轴的OuterPosition值，从而使其调整绘图部分的大小.在我的案例中，[0 0 1 1]与[0 0.0371 1.0000 0.9599]的差异很小，但是效果显然非常明显.您可以使用 get 和

Along with stacking the axes you will also note that I have set the ActivePositionProperty to position (rather than outerposition). MATLAB resizes axes automatically when the Units property is set to Normalized, and it seems like this is the main spot where the issue is arising. On resizing, MATLAB also modifies the OuterPosition value for the second axes, causing it to resize the plot portion. The difference is small, [0 0 1 1] vs. [0 0.0371 1.0000 0.9599] in my case, but the effect is obviously very pronounced. You can use get and set to fix this, but you'll have to do it on every resize which is fairly annoying. The alternative is to resize based on the Position, which seems to alleviate the issue and is a tweak present in the R2015b implementation of plotyy. This also fixes plotyy except for cases where the window is very small, so I have left my answer with the more generic approach.
