I have a system set up where the user adds a chart and then selects the type they want. If I add the chart with the colorAxis in place, how do I hide it or remove it for those charts where I don't need it?

Thanks in advance,

I also interested in the question 2. Can I feed the graph data dynamically from a Derby database using Java methods? I'm working on a project mobile app development company and I would like to use Derby.
