Hi all,

I need to get the CategoryAxis and the IChartWithAxes includes a method to receive it.

But my problem is how to get an Object of IChartWithAxes.

I'm modifying the HTML Emitter and this is the code I use till now:

Class: HTMLReportEmitter
Method:

public void startImage(IImageContent image) {
.
.
.
ExecutionContext exeContext = ((ReportContent) image.getReportContent())
				.getExecutionContext();

		Object genby = image.getGenerateBy();
		if (genby instanceof ExtendedItemDesign) {

			ExtendedItemDesign mychart = (ExtendedItemDesign) image
					.getGenerateBy();
			long deh = mychart.getHandle().getID();
			ReportDesignHandle rdh = image.getReportContent().getDesign()
					.getReportDesign();

			ExtendedItemHandle eih = (ExtendedItemHandle) rdh
					.getElementByID(deh);

			IDataQueryDefinition qd = mychart.getQuery();

			try {
				IDataEngine de = (IDataEngine) exeContext.getDataEngine();

				QueryResultSet qr = (QueryResultSet) de.execute(qd);

				IResultIterator ri = qr.getResultIterator();
				int cc = ri.getResultMetaData().getColumnCount();
				IResultMetaData rsmd = ri.getResultMetaData();


			} catch (EngineException e2) {
				e2.printStackTrace();
			} catch (BirtException e2) {
				e2.printStackTrace();
			}


			try {
;

				ChartWithAxes cwa = (ChartWithAxes) (eih.getReportItem()
						.getProperty("chart.instance"));
				
				[color="#FF0000"]IChartWithAxes icwa = (IChartWithAxes) (eih.getReportItem()
						.getProperty("chart.instance"));[/color] [color="#FF0000"]// That doesn't work!![/color]

				IAxis iaxisTemp = icwa.getCategoryAxis();
                        }

.
.
.

}

Regards,
SG

That is the script interface not the Java definition. Try:

cwa.getAxes().get(0);

When I just use

List<Axis> blabla = cwa.getAxes();

and read out the axes there ist also just a categoryAxis as an boolean variable. I can't get the binding column.

Hi Jason,

is there no way to get the Category Axis?

---
In the book Integrating and Extending BIRT (Page 170) I've found this:

IChart chart = (IChart) rptdesign.getReportElement("Chart name");

and

IChartWithAxes chart = (IChartWithAxes) rptdesign.getReportElement("Name of...");

SO I tried it like this:

IChart ic = (IChart) image.getReportContent().getReportContext().getReportRunnable().getDesignInstance().getReportElementByID(deh);

and

IChartWithAxes icwa = (IChartWithAxes) image.getReportContent().getReportContext().getReportRunnable().getDesignInstance().getReportElementByID(deh);

I got an ClassCastException for both of them.

Regards

I just tested this in my code using:
Object genby = image.getGenerateBy();
if( genby instanceof ExtendedItemDesign){

ExtendedItemDesign mychart = (ExtendedItemDesign) image.getGenerateBy();
long deh = mychart.getHandle().getID();
ReportDesignHandle rdh = image.getReportContent().getDesign().getReportDesign();

//ExtendedItemHandle eih = (ExtendedItemHandle) rdh.getBody( ).getContents( ).get( 0 );
ExtendedItemHandle eih = (ExtendedItemHandle) rdh.getElementByID(deh);

try {
Chart cm = (Chart) eih.getReportItem( ).getProperty( "chart.instance" );
if( cm instanceof ChartWithAxesImpl){
ChartWithAxesImpl cwa = (ChartWithAxesImpl) cm;
Axis[] axaBase = cwa.getBaseAxes( );
Axis axPrimaryBase = axaBase[0];
System.out.println("test");
}
} catch (ExtendedElementException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
It worked fine. Make sure you add the chart engine to the required bundles. Here is my manifest:
It is using an older version, so just disregard version numbers.

Hi Jason,

thanks again, I will test it.
I could also get the axes but there is not the categoryAxis. There was just a boolean value for categoryAxis if it's set or not.
But I need the column of this categoryAxis.

First of all i should try yours Smile

Regards,
Samo

I still can't get the categoryAxis Value (for example row['CUSTOMER']). :/

The query is on the series:

try {
Chart cm = (Chart) eih.getReportItem( ).getProperty( "chart.instance" );
if( cm instanceof ChartWithAxesImpl){
ChartWithAxesImpl cwa = (ChartWithAxesImpl) cm;
Axis[] axaBase = cwa.getBaseAxes( );
Axis axPrimaryBase = axaBase[0];
SeriesDefinition sd =axPrimaryBase.getSeriesDefinitions( ).get( 0 );
Query catQuery = sd.getSeries().get(0).getDataDefinition().get(0);
System.out.println("cat Query " + catQuery.getDefinition());
}
System.out.println("test");
} catch (ExtendedElementException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
