Blank Labels on Charts

[lukus]

Hi There,

 

None of my graphs display any lables, ledgend or numbers.  I've attached an example

 

I have been using ireport and jasperReports for a whle now and have just migrated all my reports fomr an old OSX 10.3 server to a new CentOS setup.  As a result none of my PDF reports that use graphs now display any lables of any sort.  I've upgraded all components from 3.0.0 libraries to 3.5.2 in an effort to get this fixed but to no avail.

 

I've even written a very simple report that just displays a bar graph.  The graph renders fine but again no lables or anything.  Not even any numbering on the axsis.

 

I am thinking that this is a system font issue maybe but have no idea as to how to solve it...?

 

Any help will be greatly apreciated.

 

I have already posted this on the 'JasperReports Discussion/Help' but have had no responce over the last 3 or 4 days so apoligies if you have already read this...

 

Cheers

Anyone got any suggestions on this? I'm willing to try almost anything...

Attach the .jrxml and someone may be able to take a look. Please modify your SQL to just return a few hard-coded values so that people can run it.

 

For example:
SELECT 'abc' as field1, 42 as field2
UNION SELECT 'xyz' as field1, 11 as field2

 

Also, your PDF looks like you're using the same value for the Series and Category. Really you should be using that value for the Series OR the Category.

Matt

Hi Matt,

 

thanks for the sugestions.  This isn't an actual report but rather something I knocked up for testing so I haven't been too concerned with proper pratice ;)

 

I've put in a static query with the JRXML

 

Cheers

I am able to get lebels when creating an RTF so this looks to be PDF specific...

[mdahlman]

Lukus,

 

I pasted your attached jrxml and ran it in iReport. It looks fine for me in PDF. See the attached image.

I guess you're right about it being related to what fonts are available... but I'm not sure what's going wrong. Try changing the axis or legend font to something that you're sure you have.

Matt

Hi Matt,

 

thanks for helping me out with this one.  Unfortunatly I just couldn't crack it.  I took the rather drastic measure of scrapping CentOS and installing FreeBSD and using their Ports jdk16 install...

 

java version “1.6.0_03-p4″
Java SE Runtime Environment (build 1.6.0_03-p4-root_30_mar_2009_17_29-b00)
Java HotSpot Client VM (build 1.6.0_03-p4-root_30_mar_2009_17_29-b00, mixed mode)

 

This has worked a charm.

 

Once again thanks.

 

Cheers

Thanks for the suggestion of installing fonts. I had the same issue - Charts labels were all blank in PDF output version of a report from jasperserver.

(jasperserver running on centos5)

 

yum install xorg-x11-fonts* solved it.

 

Thanks
