hc_add_yAxis: Creating multiples yAxis t use with highcharts

Description Usage Arguments Examples

Description

The Y axis or value axis. Normally this is the vertical axis, though if the chart is inverted this is the horizontal axis. Add yAxis allows to add multiple axis with a relative height between Y axis. Based upon the relative parameter the height of each Y axis is recalculated. Otherwise the parameters are as supported by Y axis.
