[BUG] ExtraEasy chart with Bar + Custom plugin extends Bar - Bars overlap & render displayed incorrect

### [BUG]
As you can read there's an ExtraEasy chart, just for example.

I really like chart.js and I want to make graphs for everything now.
But there is a problem.

Creating a very simple custom plugin that extends the `bar` makes the graph appear on the display in a very strange way.
The bars overlap each other if some series are `hidden` (I'm talking about the default bars, not the custom type).

Look at the example to understand, because it is much easier to see than to explain.

If you select all series instead the graph is displayed correctly.

**Is there a fix for this?**

[The `bars` and the `custom` bars must be positioned at the same point on the x-axis (not side by side)]
