Generally speaking, if you quote other people's charts, there should be three quotations in the whole article. First, in the text, the serial number of the cited chart should indicate the serial number of the cited literature from which the chart originated. Secondly, the title of the cited chart given with the article should also be marked with the serial number of the cited document. Third, it should be recorded in detail in the bibliography after the text. When quoting, you should indicate the source of the chart, and the information about the source should be detailed enough for readers to find the original source of the chart through this information. Generally, it should include the author, publication year, published periodicals or books. Different journals may have different requirements for the listed materials, so it is best to refer to the format guide of the target journals.

Charts are commonly used in writing scientific research papers, and their accurate use is often more vivid, concise and intuitive than the description of large paragraphs. Therefore, it is often not recommended to describe the content that can be expressed by charts or tables in long paragraphs. It's just that the process of making charts is often time-consuming and laborious, not only to highlight the key points you want to express, but also to be accurate and even beautiful. Sometimes a beautiful schematic diagram takes the author a lot of time and energy.
