Chart: Data points are not appearing on a single graph

[paulchurchward]

Hello,

I have a very simple report that only contains a single line graph. I am displaying it as a PDF froma a java web application (Using Spring). The resulting PDF is creating a multiple sets of axis and on each axis only plotting the last added data point.

See attached pdf and jrxml

 Thanks

Code:

Hi,

 

Put the chart element in the summary section, not in the detail.

 

I hope this helps.

 Thanks. That did the trick. I only see one graph now. Oddly though only the last object I put into the list that is wrapped by the JRDatasource is being graphed. 

 

ie: List<?> someList = new ArrayList<?>();

someList.add(new SomeObject(1));
someList.add(new SomeObject(1));
someList.add(new SomeObject(1));

JRDataSource = new JRBeanCollectionDataSource(someList);

only the last object is showing up on the graph...

Hi,

 

The resetType attribute of the chart dataset should be "Report".

 

I hope this helps.

Im not sure what you mean by resetType, I don't see this attribute in the jrxml file.

Thanks !

Hi,

 

I suggest you use iReport to design your reports. In JRXML, <categoryDataset> can contain a <dataset>, which in turn has the attribute resetType.

 

I hope this helps.

 I am using iReport actually which is how my jrxml came to be. From the attached jrxml file, can you plse show me the necessary modifications. Also, can you tell me where I possibly went wrong in iReport ?

 

Thanks very much

Hi,

 

Sorry, I did not pay attention to your series. You have only one dot because all numeric values are set for a single category, the one coming from your $P{JOB_NAME} parameter.

With only one job name, you see only one dot. I suspect your job names must come from a report field as well.

 

I hope this helps.

Oh, that makes sense. I cant believe I overlooked that. 

Thanks!
