IDK for sure it will remove old data... but in the "Settings" (on top tool bar), under "Charts", there are settings to control retention. By default, it's 10 years. Something to try at least....

But it does prune the data, so year back data should be pretty minimal in terms of storage relative to most disks. So I'm not sure it save that much space... But I guess if you really do have years back of the data, the Chart UI always require adjustment....
