The problem is with your data source - it returns the formatted data values as numbers and not as strings.
For example, when running http://www.pikefin.com/testjsp/JSPDataSource//mysqldatasource12.jsp?entityid=1&tqx=reqId%3A0, one of the cells looked like: {"f":-27.88,"v":-27.88} It should be: {"f":"-27.88","v":-27.88} Note the additional quotes. Fixing this should make the tooltip work. On Tue, Oct 25, 2011 at 10:25 PM, opike <[email protected]> wrote: > I'm using the line chart that is part of the core chart package.
