This one is old problem - prior MOR PRO 0.6
Problem
Instead of graphs we see only word 'Graphs'
Troubleshooting
- Check GUI log just after Graphs fails to show
LoadError (Expected /home/mor/lib/gruff.rb to define Gruff)
Check if RMagick is installed
Execute command
irb
Enter:
require 'RMagick'
If you get:
[root@localhost]# irb
irb(main):001:0> require 'RMagick'
LoadError: no such file to load -- RMagick
from (irb):1:in `require'
from (irb):1
That means RMagick is not installed.
Install RMagick
- Install RMagick
- Restart Apache
That means no font files present to draw Graphs. This usually happens to Centos/Fedora.
Execute:
cp -r -u /usr/src/mor/centos/TrueType /usr/share/fonts/default
MissingSourceFile (no such file to load -- RMagick)
- Install RMagick
- Restart Apache
NOTE: In future versions (0.6 and so on) RMagic based Graphs will be changed to Flash based graphs.
