I've created a combo chart using 3 series, one step-line and two column.
You can see a working demo here.
The issue:
Step-line data point goes in between the two columns.
in the docs there is a tickPlacement section, I would like to use the 'on' option. I've changed the xaxis.type to 'category' but it's not working.
I would appreciate any help. Thanks in advance
