You are talking about 1999?? Look at your chart comparison again.
No, the 1999 chart shows different data from 1880 through 1999 than the 2017 chart shows for that same period. You said the 1999 chart data was incomplete, suggesting that they "found" new data for the period 1880 through 1999 that was added in for the 2017 chart. That would be the only legitimate reason why the two charts are different for the same time period. So I ask, what data might be missing from the current data pool? Or are we expected to believe, even if they published incomplete data in 1999, that every data set since has been entirely complete?
