I'm facing an issue with the Highcharts Gantt library and I could use some help. By default, the library adds a top x-axis that displays months and years. I have managed to modify my custom x-axis successfully. However, I'm currently stuck on customizing this specific x-axis which is default to the lib. I have spent a significant amount of time going through the documentation, but I haven't been able to find the specific class or method to use for modifying the text color, box color, and outer lines of this x-axis. I'm wondering if it's even possible to customize these elements in Highcharts Gantt.
Any guidance or suggestions would be greatly appreciated. Thank you in advance
