Some Symbols ( Sigma ) dosn’t display in my plots and just a empty rectangle will display !
According to this
I tried :
ls -l /etc/fonts/conf.d/30-urw-aliases.conf
but dosn’t solve my problem .
I have two system with ubuntu 16.04, this is very amazing that one of them works well but the other does not! both have same ubuntu and same root version , and i used same commands for plotting.
I attached two image that one of them is plotted in one system correctly and the other in another system.
You need to have ROOTSYS defined. In the place where ROOT is installed you have a folder called bin. It contains thisroot.sh. You should “source” that file.
$ source where_root_is_installed/bin/thisroot.sh
Usually you put this command in your .profile or equivalent.
i searched for thisroot.sh but this bash file dosn’t exists . i used ubuntu 16.04 that have root package by default, so i didn’t install it with wget .
i only have a file root.sh exists in /usr/bin. and when i use :
Hi @keyvan_127.0.0.1 ,
how did you install ROOT exactly? with apt-get install root or similar? The ROOT package in the ubuntu repos is out of date (I didn’t think it was still there). Or was it via Snap?
You said that you have the folder /usr/share/root/fonts . So it looks like your root version is installed in /usr/share/root/ . In that case you find the thisroot* files in /usr/share/root/bin
There’s ROOT 5.34 in Ubuntu’s 16.04 repositories, and the installation doesn’t look like Snap to me, Snap will never put entries into /usr/bin.
Please keep in mind Ubuntu 16.04 goes into End of Life support this month and will stop recieving security and maintainence updates. I’d really recommend upgrading to a newer system aside from the ROOT issues you may be having.
My main problem is as follows :
i have two machines, one of them is thinkpad X131e and another one is thinkpad T440.
I use exactly same packages for my researches and exactly same ubuntu version ! but it is very strange for me when i plot my result, the first machine give me full notations but the second one cannot display some notations specially sigma notation.
in short, all of things are completely same in two machines but the second machine can not support from some mathematical notation ( such as sigma) in my plotes.
Assuming you installed ROOT via apt-get, I don’t think we can help much, that package corresponds to an unmaintained ROOT version (v5.34) and the package itself is also unmaintained.
