Feature Request: Support for Sub-Categories on X-Axis for Grouping Fields in Stacked-Grouped Bar Chart.

[Krishna-Chidrawar]

Hi ApexCharts Team,

I am using stacked-grouped bar charts and need the ability to introduce sub-categories on the X-axis for better grouping. Currently, while we can group series using the group property, the X-axis does not support displaying these groups as hierarchical sub-categories.

For example, I would like to categorize data under broader groups like "Sales" and "Production" while showing subcategories such as "Q1" and "Q2" within each group. Currently, the X-axis treats all categories at the same level, making it harder to differentiate groups visually.

I have attached an image to illustrate this use case. It demonstrates how hierarchical grouping can be added to the X-axis for better clarity.

Would it be possible to support multi-level X-axis categories in future versions? This feature would greatly enhance data visualization for grouped datasets.

without this subcategory labels its hard to understand this grouped stacked bar chart. I also faced this issue.
