Extent reports with diagrams by tables

[Joachim Herb]

Hello,

I would like to extend reports which contain only a diagram by a table. The table should contain the 
values (and dates) used in the diagram.

E.g. the report "Assets over Time" shows the development of the assets over time as bars. How do I 
have to change the source code of the report to add a table below the diagram containing the values 
shown in the diagram.

The table should contain the dates and the "hight" of the bars. How can this be done for the total 
hight of a bar, how for the individual parts when using the option "stacked bars"?

Thank you for your help
Joachim
