Hi everybody
I am using ns2 to implement MANET network and I use graphs and it runs fine but I do not know why this error occurs. I am using ns-2.35 under ubuntu 12.04. Any helps or suggestion why this occurs and how I can remove this error I would be appreciated.

Parameter TitleFont: can't translate `helvetica-18' into a font (defaulting to `fixed') this is the error

Welcome to LQ.

Xgraph is one of the prerequisites, usually installed
before the build of ns-allinone-2.35 :

$ sudo apt-get install \
g++ g++-4.4 autoconf automake make patch libtool libxmu-dev xgraph

The Ubuntu 12.04 xgraph package seems OK. ( xgraph_12.1-15_i386.deb ).
.. So I guess the the warnings listed in post #1
is from an xgraph you have built yourself ?

Besides that : A warning like "can't translate `helvetica-18' into a font"
can be ignored. Not an error.

Sorry, any xgraph version, any build of xgraph (from a different OS)
.. will come up with a short text message :

Quote:

can't translate `helvetica-18' into a font (defaulting to `fixed')
can't translate `helvetica-18' into a font (defaulting to `fixed')

.. in Ubuntu 12.04 - i686.

But then again, it is just a message, hardly a warning.
