请问怎样在图中插入数学公式

bluegrass

用add a text on the window.

但是很多符号不知道怎么输入阿，origin里有公式编辑器吗?

我的做法是在Word中写公式，然后拷贝到Origin里，如图。
如果安装有Mathtype，可以用插入对象的方式插入公式。

刚才实验了Mathtype，发现Origin不支持对象嵌入和连接，十分抱歉！上贴我在匆忙中写下，只实验了拷贝和粘贴的方式将公式插入到Origin中。自以为插入对象是十分普遍的功能，不好意思，对不起，耽误大家了！下次得认真些！
  
通过拷贝和粘贴的方式，可以在保持纵横比的前提下调整公式的尺寸，还是比较好用的，只是如果公式内容要修改的话需要重新来过。

It is a easy question. Firstly, insert a Text into the graph. And then right click the Text  and find 'symbol map' in the pop menu. You will input any formula using the symbol map.

  
But you can only make simple equations by this way. You can't input "any" formula this way. For example fraction, integration, matrix etc., can't be created this way. Also, the style of the equation created using symbol map isn't that great.
It's pity that Origin 7.5 still doesn't provide OLE capability.

Sure, you can do that. But for complicated formula, it's very time-consuming, and also it doesn't give professional type of formula. Personally, I think it's not worth to this. Tools like Equation Editor or Mathtype provide much better way to do formula editing. Right?
