Hi,
are there any working examples for a pie chart and a line chart?
I need the java source files where the .rptdesign is created. I have to
create those charts with de deapi, the reapi and the chart api.
Thanks in advance
Best regards
Markus Schlautmann

Hi Markus,
What do you mean the preview is broken? Can you post a screenshot of the
problem?
To add a chart into a report, you need to create an extendeditemhandle and
set your chart model into it:
ExtendedItemHandle eih = elementFactory.newExtendedItem( null,
"Chart" );//$NON-NLS-1$
eih.getReportItem( ).setProperty( "chart.instance", chartModel );
There are some examples of this in the chart examples plugin source code.
Thanks,
David

Hi David,
i meant that i could not see anything on the preview. I tried to take
some screenshots but now it works perfektly. if it will happen again i
will take a screenshot of it.
i have a problem with your code. i tried it abd now i can add a pie
chart to a grid. but it will not appear in the .rptdesign. in the
..rptdesign appears only a grid with an empty cell.
i have a question to the following code:
---
ExtendedItemHandle eih = designFactory.newExtendedItem( null, "Pie
Chart" );
---
where can i find all the allowed strings for the newExtendedItem mehtod?
You used "Chart", i have to use "Pie Chart", what else can i use? is
there a howto somewhere in the internet?
but now my main problem:
i do the following after creating the chart:
try
{
GridHandle grid = designFactory.newGridItem(null, 1, 1);
designHandle.getBody().add(grid);
//Kopf soll über die ganze Seitenbreite gehen
grid.setWidth("100%");
/*row with 1 picture in each column*/
RowHandle row = (RowHandle) grid.getRows().get(0);
CellHandle cell = (CellHandle) row.getCells().get(0);
ExtendedItemHandle eih = designFactory.newExtendedItem( null, "Pie
Chart" );
eih.getReportItem( ).setProperty( "chart.instance", cwoaPie );
cell.getContent().add(eih);
}catch(Exception e)
{
System.out.println("hallo");
}
i will paste my complete code below:

The string is the extensionName of the report item extension (see the
reportItemModel extension point). In that case it is "Chart". If you create
an extended item, you can use the name of the extension to create it using
this method. Now only crosstab and charts are extended items in BIRT.
All types of chart use the same extended item, so you don't need to change
it.
If you are unable to load the item, it probably means you are not in an OSGi
environment, so it can't load extension plugins. Please take a look at the
example in the chart examples plugin to see how this works.
Thanks,
David

David,
i'm confused.
I'm doing the following:
// Data Set
TextDataSet categoryValues = TextDataSetImpl.create( new String[]{
"New York", "Boston", "Chicago", "San Francisco", "Dallas"} );
NumberDataSet seriesOneValues = NumberDataSetImpl.create( new double[]{
54.65, 21, 75.95, 91.28, 37.43 } );
// Base Series
Series seCategory = SeriesImpl.create( );
seCategory.setDataSet( categoryValues );
SeriesDefinition sd = SeriesDefinitionImpl.create( );
cwoaPie.getSeriesDefinitions( ).add( sd );
sd.getSeriesPalette( ).shift( 0 );
sd.getSeries( ).add( seCategory );
// Orthogonal Series
PieSeries sePie = (PieSeries) PieSeriesImpl.create( );
sePie.setDataSet( seriesOneValues );
sePie.setSeriesIdentifier( "Cities" );
sePie.setExplosion( 5 );
SeriesDefinition sdCity = SeriesDefinitionImpl.create( );
sd.getSeriesDefinitions( ).add( sdCity );
sdCity.getSeries( ).add( sePie );
Addionally to these Datasets i have to define a column binding?
Best Regards

Markus,
Been away a bit, but in the examples that you picked up earlier, there is
an example of inserting a pie chart into a report in the SalesReport example.
Perhaps that will help?

If the chart is inside a report, you cannot use hard-coded data. You must
use the data from the report. So define column bindings, and add references
to them in the chart model. Then the report will automatically populate the
chart data using the data from the db.
If you really need hard-coded data, you can use a scripted dataset then at
the report level, and use the dataset in the chart, but you still need to
define bindings like I mentioned.
Thanks,
David

thank you very much for spending so much time in this group!
i hope this will be my last question in this thread.
i tried it as you told me. I created a data source and a data set and
defined column bindings.
My report compiles without errors now, but i get warnings:

Finished buildPieChartReport() method
This happens every time i access the extended item handle, like
eih.setHeight() or eih.setWidth()......
How can i solve this?
I think this is nothing critical, the report design looks fine now, the
chart is in my design. The design is compiled without errors or warnings
into pdf. But in my pdf is no chart. What have i done wrong?
Best Regards
