Hello Team,
Plot lines are no longer supported in version 5.0.11. ("https://code.highcharts.com/5.0.11/highcharts.js")
Please check fiddle: https://jsfiddle.net/d76a98u1/1/
Same code is supported by higher version in jsfiddle (https://code.highcharts.com/highcharts.js").
Please check fiddle: https://jsfiddle.net/d76a98u1/2/
Can you please help changes in the older version. so it supports all the charts making use of plot lines. So I don't have to upgrade to newer version of high charts.
