At the moment, when I export report to XLSX (MS Excel) format, there is a white void at the top of the spreadsheet preceding the data - I guess, it is supposed to be the chart :). The report is also exported as HTML, PDF and JSON, all three without any visible issue.
I'm using JasperReport "community" edition. Here are the relevant lines from my build.gradle:
implementation group: 'net.sf.jasperreports', name: 'jasperreports', version: "6.6.0"
implementation group: 'net.sf.jasperreports', name: 'jasperreports-fonts', version: '6.0.0'
I found a few posts suggesting to set the property net.sf.jasperreports.export.xls.ignore.graphics to false.
OK, did that in the report template:
<jasperReport ..>
<property name="net.sf.jasperreports.export.xls.ignore.graphics" value="false"/>
Still a white hole instead of a chart.
Is there a solution to this issue, or do I just have to live with it?
