Chart title at runtime [message #165829]

Hi I am using Birt 2.0.1 and I have a question about setting the title of
a chart in the beforeGeneration method.
I have a table that is bound to a scripted dataset and a chart that is
also bound to a different scripted dataset.

Table has 2 rows first row is based on object from 1st dataset and second
row contains a dual axis line chart that is populated based on the
value of the 1st row. That is working fine. I want to set the title of the
chart to the value in the first row and i can't seem to
figure out how. I have tried setting a report parameter in the expression
builder of the first row and accessing it via
context.getExternalContext().getScriptable().getParameterVal ue() and it
always seems to be null.

Also tried using a GlobalVariable and that to is also null.

Any help or pointer to where I am going wrong.

Thanks
DT

Update:
When I view the report in pdf it works fine the chart title gets displayed
correctly. However when I view as html the title remains blank.

in the beforeGeneration method of chart scripting, you can access the
dataset inside the series and get the first value, then set it in the title.

Thanks,

David
