26 The composition of a line chart includes:
27
28 1. **Horizontal axis (X-axis): **The horizontal axis in a line graph is the horizontal axis, usually used to display continuous variables such as data classification or time.
29 1. **Vertical axis (Y-axis):** The vertical axis in a line chart is the axis in the vertical direction, usually used to display numerical values or quantities of data.
30 1. **Point: ** Each point represents the data value at a specific position on the horizontal and vertical axes. In a line chart, the line connecting all points can show the trend and change of the data.
31 1. **Line:** The lines in a line chart are straight lines formed by connecting data points, representing the trend of data changes. The trend of the lines can intuitively show the growth, decrease, or fluctuation of the data.
