Just wanted to share this. A working example of a vertical x-axis. I also found this post about styling of the chart: docs.dhtmlx.com/touch/doku.php?i … _map_chart that indicates the chart parts that you can css yourself.
If you have longer x-axis labels, increase the bottom padding. You can also change the angle to your specific one, the example uses -90 degrees.
