TeeChart question

I would like to make a game called Rappatongo on the computer.

There is a clock running in the right lower corner. If nothing has been
said, the clock is transoarant. I would like to see the same in the computer
version.

If for a second someone is talking, I would like that a colour is made of
1/60 of the TeeChart. Also at 2 seconds, and so on. How can I get this to
work? (If there is another component, than thats fine with me too,
ofcourse).

With kind regards,

Danny
