Echarts displays numerical values on one y-axis and its percentage on one y-axis. How to make it show only one broken line?

echarts line chart, double y-axis, there is already a data corresponding to the y-axis. We need to get the percentage of the corresponding data according to its data to form another y-axis
I get the corresponding percentage of the data, but show two curves that are not coincident.
