I will try this, but can't at this time.
I did some additional experimentation and found that if I run the
service as root:root, there are not issues with the core R plotting
functions. My issues only occur when the service is using user:
zeppelin group: zeppelin. This s a permissions problem. I just don't
know how to fix it.
Do you think version 0.8 will has this fixed? my zeppelin.service is
listed below and is based on a user group posing and me copying then
modifying the httpd.service files.
Thanks
Joe

Do you mind to try zeppelin 0.8 branch ? You need to build it from source

A follow up.
I am running zeppelin as a service on a Fedora 25 server controlled by
systemd (systemctl ...). I create a user and group, zeppelin, with
/sbin/nologin and home /dir1/zeppelin. I set up shiro.ini for my ldap
authetication. This issue did not occur when I was testing, starting
server with command line script or daemon as root user, and logging in
as anonymous on the zeppelin url.
Googleviz charts do work, only R specific plot, ggplot2, have this issue.
Thanks
Joe
