I am using Parent/Child rows and want to display multiple Events in one line for the children.
With the use of uniqueNames: true in my yAxis options i was able to archive this, but if i use multiple series the height of each row is getting increasing. It seems like one row now contains invisible rows inside. https://jsfiddle.net/usf2gzvh
Is there a way to get the height of each row back to normal size like it is with one series? https://jsfiddle.net/fugqz4vm/
