Hi,
Please look at the scripting specification:
http://www.eclipse.org/birt/wiki/index.php?n=BPS.BPS18
To answer your first question, it will only be possible to extract data from
a series dataset itself in 1.0.1, so if you access the runtime model in your
script, you can try that. I would try that in beforeDrawBlock().
If you want to show the current week over the bars of a bar chart, that
should be possible without scripting. Go To Attributes->Y series and add the
base value to the datapoint.
You can add blocks to the chart and use the layout to specify where those
new blocks go. If you want to bind them through data, you would need to
script using beforeDrawBlock() like I mentioned previously.
Thanks,
David

Unfornutately, there is no way to make the labels appear with different
vertical position. We need to improve the renderer to identify the newline
character and render it correctly. I think you can enter any separator
character in the UI, but the renderer will just output it like you wrote it.
For instance \n will be rendered as \n.
If you really need that though, you can add your own Bar Renderer
implementation that renders the new line character, and why not contribute
it, so we can add this feature in the original Bar Renderer implementation
and other renderers too.
To add a new renderer implementation, please check the Chart engine BPS
entry in the wiki, http://www.eclipse.org/birt/wiki/index.php?n=BPS.BPS39
although there should be some documentation inside the BIRT documentation I
believe.
Regarding the blocks, there is a bugzilla entry regarding that, as there is
an issue with block layout. The entry contains a sample code as well, but
you might want to wait until it is fixed to use it:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=103062
Thanks,
David
