Hello, I've created a new toollbar item in a chart. I see it but I did'nt see how to do functionality to it. What can I do ? I've have to add a mouserlistatner to chart? how can I see what commandID is pressing for the tollbar?

Hello I've a an arraylist that contains the Data ina a matrix as "Customer, NumberOfIncidenceslast2years, NumberOfIncidenceslastyear,NumberOfIncidenceslast6month" I've seen the documentation i've to use the crosstab data provider but it not works with a Arrayist. There's any workarround?
