I believe that everyone will encounter a very troublesome thing when sorting out the pictures and tables of the document. It is the serial number of this chart. I want it to be automatically updated, especially in the process of writing a graduation thesis. This function is really important. I didn’t think much about it before, but when I was doing a report these days , because a lot of pictures need to be inserted, and the report must be completed in cooperation with others, and the most important part of this function is to deal with multiple revisions.
In fact, many people do, but some people must have encountered some problems in the process of trying, such as the one I mentioned below: first of all,
insert captions and create new tags in the reference, that is, figures and tables. A graph is a label, and a table is also a label. 
The following is to realize the automatic numbering of this number. I want it to be "chapter number-picture number", such as Figure 2-1, which represents the first picture of the second chapter.
As shown in the picture, click the number and click OK.
Then the problem came, click OK, he prompted to create a multi-level list, this problem has troubled me for a long time, I don’t know where to set it, and then I happened to see a post that helped me solve this problem 
,
What this question is about is that we want to use chapter numbers to automatically number the charts, and we have also selected Title 1, which means that each chapter is required to be renumbered. We need to implement automatic numbering for the style of Title 1.
First of all, please see that Heading 1 looks like this before it is automatically numbered.
Then we click on the multi-level list in the start to define a new multi-level list style. As shown in the picture
, you can set the font. It is recommended that this font be consistent with the style and size of the document title 1. The
most important thing is the following step. Click the "More" button and choose to link this newly created multi-level list to Title 1, and After the numbering, set it to a space
and finally click OK. The effect is as shown in the figure below. When we set the text in the document to the heading 1 style, it can be automatically numbered
Finally, go back to this step, click OK and it will be easy.
The effect is as shown in the picture below
and it is so troublesome when you only need the first picture. For the following pictures, you only need to copy this sentence and change the name of the picture. Well, the numbers don’t need to be changed. Finally, press Ctrl+A to select all, and then press F9 to update the document. All pictures are automatically named.
And after this document is sent to others, although there is no caption created by me on his computer where the reference is made, the copy method I mentioned above can be used, which is really easy to use.
The same is true for the form, so I won't repeat it.
But in the end, we can say that in the case of cross-references, this effect can be achieved. The
operation is as follows:
Ask us which caption to insert in this place, we just need to select and insert it according to the name of the picture, and the number here will follow The real number of this picture changes, saving us a lot of trouble.
hope that it can help us! ! !
