I posted my answer in the support ticket you have opened. For convenience I am pasting my reply below:
The described functionality is not supported out of the box in Kendo UI Chart. As a possible workaround I would suggest to create a covered <div> HTML element which contains the additional text and place this element over the chart. For convenience, I created a jsFiddle example which illustrates such approach in action.
Regarding the "additional title"
which you mentioned with the first post from this thread - currently such functionality is not supported, but this idea sounds good and I would suggest to send it as a feature request at our UserVoice page
. This way the community would be able to vote and comment it and if this suggestion turns out to be popular we will consider its implementation.
