Hi,
i am currently trying to create a new chart type. Now i was wondering how
i could make BIRT not using aggregate functions on my Value(Y) series.
By default it is always the "sum" function. Is there a way to allow selection of
NONE in the aggregation combo ?
My dataset could be sth like
x / y
1 / 10
2 / 10
2 / 30
3 / 5
etc.
I my IDataSetProcessor i added the ids to getDataDefIdsForGrouping(). But now the two Y values at 2 are always
added to each other. So there is one datapoint 2 / 40 when doing my rendering.
thx for any advice
Dennis

Hi,
the error is occuring using my own chart implementation. Using same data etc. with BarChart works.
It is in the method
AbstractChartBaseQueryGenerator.addValueSeriesAggregateBindingForGrouping
The line
Series series = orthSD.getDesignTimeSeries( );
returns null for series, which causes NPE in the following lines calling
series.getClass( )
This only happens when running my report in the birt runtime using ReportRunner. Running it in the rcp designer works fine.
To create my chart extension, i used the example you send me a while ago.
I noticed i get the same error, when my new chart plugin is not placed in the plugins folder of the runtime. Now i am
wondering when birt first accesses the extensions and if maybe my chart leads to invalid rtpdesign file. But then running
the report from ReportDesingner shouldn't work, which it does.

Dennis,
Can you post the manifest file for your chart extension?
