Hello,
I just installed version 1.6 of eGroupWare on a SLES10.
To run the GANTT chart I install the latest version JPGRAH (Version 2.3.4).
Here is the procedure:
Download JPGRAH 2.3.4
Installing in / projectmanger/inc/jpgraph-2.3.4
Change the path in the file class.projectmanager_ganttchart.inc.php
line 72 and 73 by replacing JPGRAPH1.5.2 jpgraph-2.3.4
Change the path in the jpg-config.inc.php file so that it can find the fonts
define ( “cache_dir”, “/ test / eGroupWare / tmp /”;
define ( “TTF_DIR”, “/ test/eGroupWare/projectmanager/inc/ttf-bitstream-vera-1.10 /”;
I created a project and I request to display the Gantt
and here is the error that appears on the screen:
“Sanity check for automatic Gantt chart size failed. Either the width (= 773) or height (= 1460288968) is larger than MAX_GANTTIMG_SIZE. This could potentially be caused by a wrong date in one of the activities.”

can someone help me?
thank you.
