Hello Sagi,
I am afraid what you would like to achieve is currently not supported by Kendo UI Chart and there is no a suitable workaround I can suggest. Actually there is a public item with the same idea in our UserVoice portal - if you wish you may cast a vote, leave a comment or monitor the community's interest in it here. The more votes the suggestion collects, the sooner will be implemented.
Regards,
