Graphs does not appear

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

Magick::ImageMagickError (unable to read font `/usr/share/fonts/default/TrueType/arial.ttf')

That means no font files present to draw Graphs. This usually happens to Centos/Fedora.

Execute:

cp -r /usr/src/mor/centos/TrueType /usr/share/fonts/default

NOTE: In future versions (0.6 and so on) RMagic based Graphs will be changed to Flash based graphs.
