Definition of three-line graph
A three-line diagram is a three-line table.
Experimental measurement and calculation data are the core contents of scientific papers. As one of the main forms of data expression, tables are widely used because of their clear function of quantitatively expressing quantitative information.
The three-line table is concise in form, clear in function and easy to read, so it is recommended to be used in scientific papers. Three-line tables usually have only three lines, namely, top line, bottom line and column line (see figure, note: there is no vertical line). The upper and lower lines are thick lines and the column lines are thin lines. Of course, a three-line meter doesn't necessarily have only three lines, and auxiliary lines can be added when necessary, but no matter how many auxiliary lines are added, it is still called a three-line meter.
The elements of three-line table include: preface, title, item column, text and comments.
