Placing text in donut chart hole

[Mark]

I need to place some text in the center of a donut chart's hole.  I looked at the following guidelines:

http://docs.telerik.com/kendo-ui/controls/charts/how-to/donut-chart-hole-text

Given my current scenario I am not able to take advantage of the CSS option.  So I am trying the render event approach.  I get a typescript error on the "e.sender.surface.draw(text);" statement which says "Property 'surface' does not exist on type 'Chart'."

Hello Mark,

Thank you for reporting this.

I can confirm this is an issue with generating the typescript directives.

I logged an issue in our repository on GitHub, so our developers can investigate it further and for you to track its progress at:

In addition, I updated your Telerik points for bringing this to our attention.
