Description: 1) In drawing two-dimensional graphical interface in the coordinate system in which the x-axis is located in the middle of the plot area, y-axis in the drawing area to the left.
2) According to the following test data, in 1) Title of the coordinate system to draw data points, each data point with a small cross sign indicates, and
Crossed edges to (x, y) data points marked out the format of coordinate values , the final line connecting adjacent data points.
Number of data points x coordinate y coordinate
