It could be that the default PHP settings on the server need to be increased to allow the graph to be fully displayed. The following article has instructions in how to do that.

Let us know if this works or not.

The images display fine on the screen, this cutoff is only when you try to download them to any format that is not an svg (svg seems to work fine)

Try doing the changes to the php.ini file as the scripts that create the downloaded images, still use PHP to generate them.
If the changes still do not work, run the following as root
Then download an image and post any errors that you see in the window running the tail command.

Those messages are really "PHP Warning:". Even though the word error in is in the entry, it is still a Warning.
Can you run the following commands and post the version of the 2 applications that generate the images and PDF files?
Code: Select all
/usr/local/bin/wkhtmltopdf -V
/usr/local/bin/wkhtmltoimage -V
What version of Nagios XI is the server running?

Thanks for letting me know the versions of the tools.
I was able to recreate the issue you are having and confirmed it is a Bug and I filed a Bug fix to get it fixed.
The ID for the Bug Fix is 13979.
Downloading PDF and SVG files seem to be OK.
