How to render strip lines behind the series in Chart?

Essential Chart supports rendering strip line behind the series by using zIndex property of strip line. This property takes values as behind and over. By default, strip line appears in front of the series so the part of the series overlapping with strip line is not visible. You can avoid this by setting the value of zIndex property as behind.

JS

The above code example renders the chart as follows.
