A quick follow up - perhaps something could be possible once visual templates are implemented, you can Follow that here. You can see here the jQuery wayt for that, yet I can't say if it will be applicable to Blazor - it has not been tested and I am not sure it can be supported considering that generally in Blazor you don't modify the DOM yourself If you ensure to clean it up I don't expect it to be an issue, though. If you would want to try that approach, click the Vote and Follow buttons on the Feedback Portal page for the visual template to be implemented for the Blazor charts - this will raise its priority and you will get emails for status changes (such as when we know when it will be available). Note that the Kendo drawing API may need to be fetched separately on the page (see sample project here).

The chart renders either with SVG elements, or with a <canvas> tag. Neither of them can take HTML markup to render, and so the chart labels cannot render HTML. To add new lines you can use the \n symbol.
With that said, I must mark this as "declined" because technically it is not feasible to put HTML directly on the chart surface.
