We have an issue where encoded characters (for example: ö) in the chart category field cause the label to be misaligned.
You can see this in the following dojo example here: https://dojo.telerik.com/aMEYaziy
This dojo is based on your example (https://demos.telerik.com/kendo-ui/bar-charts/index) but I've added an encoded 'ö' character to the label for Februrary.
In our application we are passing our the labels down via ajax, and defining the field in series.categoryField (as oposed to the hard-coded values in your demo and dojo), but the effect is the same.
Please let us know what the problem is and how we can resolve it.
