[BUG] xterm and btop -> no graph and no "Option"

Any bug that can be solved by just reading the prerequisites section of the README will likely be ignored.

Describe the bug

I am using arch linux with pure xterm package.

When I start btop, it looks like on the screenshot

It does not matter what I configure for the graph, I never see one.

If I use lxterminal, btop has graphs.

I could not find an idea what xterm is missing. I also could not find any issue fitting to my problem

To Reproduce

• Install plain arch linux
• Install i3wm, xterm, btop
• Open btop
• Graphs are missing

Expected behavior

btop shows graps

GDB Backtrace

If btop++ is crashing at start the following steps could be helpful:

(Extra helpful if compiled with make OPTFLAGS="-O0 -g")

1. run (linux): gdb btop (macos): lldb btop

2. r to run, wait for crash and press enter if prompted, CTRL+L to clear screen if needed.

3. (gdb): thread apply all bt (lldb): bt all to get backtrace for all threads

4. Copy and paste the backtrace here:

Can you run echo $TERM?

In my case it returns xterm-256color and I get the right output:

[stevleibelt]

@stefanos82

echo $TERM
xterm-256color

Totally strange. I am using i3wm with xinit. You re using kde, right?

[stefanos82]

Nope, I'm using XFCE4.
