title: How can I generate a sine chart at runtime using TCustomTeeFunction and TButton?
body: <p>I'd like to generate sine chart. I've used this <a href="http://www.teechart.net/docs/teechart/vclfmx/lib/html/TCustomTeeFunction.html" rel="nofollow noreferrer">http://www.teechart.net/docs/teechart/vclfmx/lib/html/TCustomTeeFunction.html</a>
  However it is added at design time. How to use that TCustomTee function only after clicking at Button during runtime?</p>
