Hi Team,

First of all great work on the Highcharts. It is very helpful in far many way I can describe in representing complex data.

Recently, I have come across a requirement where I need to use Dual-Xaixs of which one is a grouped. i.e for instance, say my bottom X-Axis is of months my top X-Axis should be of quarters (3 months ~ A quarter). I do not see any example or hacks which I can use to achieve this. Please, let me know if this is possible. If so, Please point me in the right direction so that I can use this feature.

Best Regards,
Prasanth.
