MATLAB：把一个圈数上的图 [英] matlab: putting a circled number onto a graph

问题描述

我想提出一个圆圈数字上的图形作为标记的附近的（但不是）一个点。听起来很简单，但我也想成为不变的变焦/长宽比的变化。

I want to put a circled number on a graph as a marker near (but not on) a point. Sounds easy, but I also want to be invariant of zoom/aspect ratio changes.

由于这种不变的，我不能画一个圆作为线对象（不重绘后的重新调整）;如果我用一个圆圈标记，我不得不调整其在重新调整所抵消。

Because of this invariant, I can't draw a circle as a line object (without redrawing it upon rescale); if I use a circle marker, I'd have to adjust its offset upon rescale.

我能想到的最简单的方法就是使用统一code或宋体字＆＃x2460; ＆＃x2461; ＆＃x2462;在等了文本（）函数的字符串。但单code似乎没有工作的权利，而下面的示例只＆＃x2460工程;并没有为其它数目（其产生矩形框）：

The simplest approach I can think of is to use the Unicode or Wingdings characters ① ② ③ etc. in a string for the text() function. But unicode doesn't seem to work right, and the following sample only works with ① and not for the other numbers (which yield rectangle boxes):

作品：

clf; text(0.5,0.5,char(129),'FontName','WingDings')

不工作（应该是一个圆圈2）：

doesn't work (should be a circled 2):

clf; text(0.5,0.5,char(130),'FontName','WingDings')

是什么给了，任何人都可以提出一个解决办法？

What gives, and can anyone suggest a workaround?

推荐答案

这似乎为我工作，利用Matlab的乳胶间preTER和 \\ textcircled ：

This seems to work for me, uses Matlab's latex interpreter, and \textcircled:

clf; text(0.5, 0.5, '$\textcircled{2}$', 'Interpreter', 'latex')

的 \\ textcircled 命令似乎有一定的偏移问题的，也许你可以尝试提高使用乳胶命令，并让我们知道：）

The \textcircled command seems have some offset problems, maybe you can try to improve the used latex command and let us know :)

按照上面的链接，例如，我得到更好的效果：

Following the above link, for example, I get better results with:

clf; text(0.5, 0.5, '$\raisebox{.5pt}{\textcircled{\raisebox{-.9pt} {2}}}$', 'Interpreter', 'latex')

不过，两位数字看起来糟透了。

Still, two digit numbers look awful.
