Created attachment 8734 the shape of the bars changed to balloons In xfce4-cpugraph-plugin version >= 1.1.0 the shape of the bars changed to balloons. This seems to apply to all Arch-based distros like Antergos and ArcoLinux. I prefer to use bars.
Which theme are you using? If not Adwaita or Greybird, can you try them?
Sorry for the late reply. I'm using BlackMATE and there seems to be the problem. The normal bars occur when changing to any other theme.
That's a theme issue, unfortunately it can't be fixed by cpugraph-plugin.
Yes, it's a theme issue, not one of cpugraph-plugin, so this thread can be closed.
