I have already replied to your support ticket with the same question, however I am pasting my reply here too so the other users who are following this thread can read it:
I am afraid what you would like to achieve is not supported at present by Kendo UI StockChart. We will appreciate it if you submit this idea as a feature request at our UserVoice portal. This way the community would be able to vote and comment it and if the suggestion gains popularity we will consider its implementation. The more votes the suggestion collects, the higher priority will have.
