Coldfusion chart help needed - repost

I have a very small problem. Maybe someone can help me out. Also, I am looking for a person who has experienced with Coldfusion a bit in order to ask help in the future too. The description of my problem is how to limit y axis for dynamically refreshing cfchart. I use the same code as on the page [login to view URL] Maybe someone also know how to set time type to the x axi too. My main purpose is to show daily stock prices data on this chart. If someone has any questions I am happy to answer them.
