The academic hall stipulates that the appearance of pictures in the paper should be scanned together with the text, and the pictures should be read first and then the text. A chart should have a chart sequence and a chart title, which are marked at the bottom of the chart. The figure sequence is numbered consecutively with Arabic numerals, and there is a character between the figure sequence and the figure name, which is arranged in the center of the figure with a font smaller than the text number 1 (small five-song style). Charts can also be labeled, that is, illustrations. Legend can be directly marked in the blank space of the drawing, or it can be marked with ";"in the same font as the title of the drawing. Labeled in turn under the title of the drawing between each note. The numbers are separate. When there are only 1 graphs in the full text, the graph order is also "graph 1". Due to the limitation of layout, when the picture must be placed horizontally, it should be placed at the top, bottom, left and right, the title of the picture should be placed at the bottom of the picture, and the top, bottom, left and right should be typeset from bottom to top.

When writing a paper, if you can introduce clear information in short words, don't use charts. Illustrations should be logical, schematic, symbolic and concise, and realism should not be emphasized.
