I have search the forum to solve this and I have performed all action but I still can not fix this. My survey is in Greek and all characters are shown ok EXCEPT the graphs characters in the statistics.
I have put the arail.ttf in the fonts directory, I have set the arial.ttf in the config.php file with $chartfontfile = 'arial.ttf'; and still, as you can see in the attachment, I can not get them to display correctly. Any other ideas?
Thanks.

Hello michelk,

I had this same issue. The resolve is to edit classes\pchart\pchart\pChart.class.

$this->setFontProperties("tahoma.ttf",8);
to
$this->setFontProperties("arial.ttf",8);

It worked form me.

But first of all, clear your browser cache and limesurvey/temp dir (chart pngs are stored there).

Please also check that the font type you chose exists.

I' have same problem with spanish characters.

I've cleaned all temporary folders (windows,user,limesurvey)
I've copyed arial.ttf, tahoma.ttf and verdana.ttf to /fonts folder in limesurvey.
I've changed chartfontfile from "auto" to those in config.php.
I've changed $this->setFontProperties("tahoma.ttf",8); to arial and verdana in classes\pchart\pchart\pChart.class
I've stopped and restarted Apache, and did not works.
Any other idea?
Thanks in advance.

I remember that this problem could also be related to some server setting or a server bug but I don't remember the details

Maybe updating your PHP version could also solve the problem.

Maybe Google knows more details?!
