Graphs does not appear

From KolmiSoft Wiki

This one is old problem - prior MOR PRO 0.6

Contents 1 Problem 2 Troubleshooting 2.1 LoadError (Expected /home/mor/lib/gruff.rb to define Gruff) 2.1.1 Check if RMagick is installed 2.1.2 Install RMagick 2.2 Magick::ImageMagickError (unable to read font `/usr/share/fonts/default/TrueType/arial.ttf') 2.3 MissingSourceFile (no such file to load -- RMagick)

[edit] Problem

Instead of graphs we see only word 'Graphs'

[edit] Troubleshooting

• Check GUI log just after Graphs fails to show

[edit] LoadError (Expected /home/mor/lib/gruff.rb to define Gruff)

[edit] 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.

[edit] Install RMagick

• Install RMagick
• Restart Apache

[edit] 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 -u /usr/src/mor/centos/TrueType /usr/share/fonts/default

[edit] 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.
