Hi there,  
In a Power Chart I need to display an histogram (bars) to show the calories of different foods (it's only an example).  
My X-Axis is based on "categories of food" like:

```
Orange
Banana
Cucumber
Tomato

```

I wish to add a second X-Axis that define the family of the food just below the first x-axis. It should show:

```
Fruit (for Orange and Banana)
Vegetable (for Cucumber and Tomato)

```

Is this a feature available?  
Thank you in advance for sharing your experience or for any hints.

Enrico

My [Embr Charts](https://forum.inductiveautomation.com/t/musson-industrial-s-embr-charts-module/91618) module’s `Chart.js` component comes with a plugin that supports hierarchical axes.

Checkout this example, it sounds like what you’re looking for:

> **[Static Expanding | chartjs-plugin-hierarchical](https://www.sgratzl.com/chartjs-plugin-hierarchical/examples/static.html)**
>
> Chart.js module for hierarchical categories

It also supports expanding/collapsing based on group.
