I've lost the scale on one of my graphs

Not sure how I've managed this, but I seem to have lost the scale on the side of my CPU temperature graph.



Could someone tell me how to put this back?

Thanks.

Just click in the graph area.

I only tried right clicking.

Thankyou for the easiest fix of anything, ever.
