This is discussed on another thread.

In the thread, it is discussed whether upcoming octave 4.2 should support 
gnuplot 4.6.

I only use ubuntu and lububtu for linux distribution. 



I have installed lubuntu 16.04 to a PC. Default gnuplot version is 4.6.6. 
And it also have gnuplot5 packages and their version is 5.0.3. 

However, ubuntu 14.04 LTS, which is still used by many people, does not have 
gnuplot 5.0 in official repo. nor ppa.

If this distribution did not get around to update to a newer version 
of gnuplot I am pretty sure they would not update update octave either.
People who would want to compile their own new version of octave can as 
well compile a newer version of gnuplot (and install it in some special location
if they want to keep the old version). 
So I think we should keep 5.x version of gnuplot as a requirement for the 
upcoming octave 4.2 release.​

Is gnuplot version 5 requirements for octave 4.2? 


For windows, mxe-octave provides gnuplot 5.0.4.

For Mac OS X, pre-built gnuplot 5 seem to be available.

On major commercial OS, drop of gnuplot 4.6 seem not to be a problem. 

For users who use linux distributions (or other Unix family?), this is a  
problem.
