Unable to export the chart data into CSV

[njrfrens]

I'm generating a bar chart using Jasper Reports. I'm showing that chart as an image in the JSP file.

There is a click button on the Jsp Page. On click of button, the data used for graph should be exported as a CSV File.

I'm using below code to export to CSV.

but it is not exporting the data. Just creating the file with zero bytes.

 

 

Code:

JasperPrint jasperPrintJRCsvExporter csvExporter = new JRCsvExporter();csvExporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);csvExporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME,"xyz.csv");csvExporter.exportReport();

Hi Can any one please inform me if there is any solution for it...?

 

At least please inform me whether this is feasible or not?

JasperReports exporters do not export data, but reports.  If your report consists only of a chart, the CSV export would be empty as images/charts are not exported to CSV.

If you want to see data in the CSV, you'll need to design a report that displays the data.
