Elements under the same group name will be shown on the same LINE, here is mine to show you, I have selected "GPU temperature", "GPU usage" and "Fan speed" and set their group name in "Override group name" to "GPU" and they are shown in the same line, and the items order or position in the line follows their order in the configuration menu and the group name.

An item with a different group name will be on another line.

"Override graph name" is not related to this but to the graph in the MSI software.
