[原创]在Matlab中，如何实现xticklabel的旋转？

在撰写科技论文时，不可避免的要使用图片显示试验结果。excel固然可以用来画图，但是excel画出来的图片不够精美，漂亮。Matlab是一个很强大的工具(我对其他功能知之甚少)，可以画出很精美的图片，并且可以直接存储为.eps格式，方便在LaTex中调用。

我在使用Matlab是遇到了一个问题，就是由于xticklabel的字符串过长，导致多个ticklabel重叠。

首先，为初学者解释一下什么是ticklabel？什么是label？

一般情况下，label是可以通过属性设置其旋转的，但是，这并不是我们要旋转的东西，我们想旋转的是ticklabel，而ticklabel在axis属性对话框中通过设置style只能设置FontSize和FontWeight等属性，并不能旋转。

我通过一个函数实现ticklabel的旋转

function th=rotateticklabel(h,rot,demo)

%ROTATETICKLABEL rotates tick labels

%   TH=ROTATETICKLABEL(H,ROT) ris the calling form where H is a handle to

%   the axis that contains the XTickLabels that are to be rotated. ROT is

%   an optional parameter that specifies the angle of rotation. The default

%   angle is 90. TH is a handle to the text objects created. For long

%   strings such as those produced by datetick, you may have to adjust the

%   position of the axes so the labels don"t get cut off.

%

%   Of course, GCA can be substituted for H if desired.

%

%   TH=ROTATETICKLABEL([],[],"demo") shows a demo figure.

%

%   Known deficiencies: if tick labels are raised to a power, the power

%   will be lost after rotation.

%

%   See also datetick.

%DEMO:

if nargin==3

x=[now-.7 now-.3 now];

y=[20 35 15];

figure

plot(x,y,".-")

datetick("x",0,"keepticks")

h=gca;

set(h,"position",[0.13 0.35 0.775 0.55])

rot=90;

end

%set the default rotation if user doesn"t specify

if nargin==1

rot=90;

end

%make sure the rotation is in the range 0:360(brute force method)

% while rot>360

%     rot=rot-360;

% end

% while rot<0

%     rot=rot+360;

% end

%get current tick labels

a=get(h,"XTickLabel");

%erase current tick labels from figure

set(h,"XTickLabel",[]);

%get tick label positions

b=get(h,"XTick");

c=get(h,"YTick");

%make new tick labels

if rot<180

th=text(b,repmat(c(1)-.1*(c(2)-c(1)),length(b),1),a,"HorizontalAlignment","right","fontsize",14,"fontweight","bold","rotation",rot);

else

th=text(b,repmat(c(1)-.1*(c(2)-c(1)),length(b),1),a,"HorizontalAlignment","left","fontsize",14,"fontweight","bold","rotation",rot);

end

如何使用这个函数呢？

x = round(rand(5,3)*10);

h=bar(x,1,"group");

set(gca,"xticklabels",{"benchmark1","benchmark2","benchmark3","benchmark4","benchmark5"});

h = gca;

th=rotateticklabel(h, 45);

效果
