ApexCharts.js Area Chart

I am using the ApexCharts.js plugin and i would like the area chart to use the same y-axis for two lines. I have attached an image below.


I want the yellow and the blue lines to share the same y-axis. However, in the screenshot below, you will see that they do not. The yellow line is displayed higher than the blue line, even though its values are smaller. How can I configure the graph to display them on the same axis?
