problem description
the requirement is that there is a set of data data,dat.x is x-axis time Abscissa, data.y is y-axis data,data.y vertical range fluctuates up and down 1. Now it is necessary to change the y-coordinate of the origin coordinate of the graph to start with 1, the part exceeding 1 is above the x-axis, and the lower than 1 is just below the x-axis. The current graph is as follows
