A flowchart consists of symbols with a definite meaning, simple explanatory text, and various lines. (See also the meaning of flowchart symbols in axure software)
The common practice of drawing flowchart patterns and procedures is: ① start with hexagonal or rounded rectangles or ellipses; the ② rectangle box represents the specific activity process, the ③ diamond box is the decision, audit, judgment, ④ end terminates with Ellipse; ⑤ parallelogram represents the input output; ⑥ arrows represent the direction of the workflow.
It is also stipulated that the process line is from bottom to top or right-to-left, must have an arrow, in addition, you can not draw arrows, the flow line of the default is from top to bottom or left to right.
The explanatory text within the symbol is as concise as possible, usually written in left-to-right and top-down mode, regardless of flow direction. If the descriptive text is more, the symbol is not finished, you can use the annotation character. If the callout character interferes with or affects the flow of the graphic, the reference symbol should be noted on the body of another page. 3. Basic structure of Flowchart
