If instead I had supplied a time series for eight years ending just prior to all of OP's data, you wouldn't discuss "comparing" the charts (I assume!), so it's a little unclear what the concern is with comparison.
If you just need the last few data points, of course you can either just look at OP's chart, or if you don't trust that data, then quickly get the data yourself. Again you can even create an account on slight.run and recreate the full graph if you prefer.
