re: Average New home price biggest drop since 2008

help an old man with bad eyes. What are the absolute numbers in dollars? I an see the % is about 11% in bottom chart, but that doesn't make sense as the price seems to be at 570k but now well below 500 (ok I see in top right 456,800), so seems like a bigger % drop than what is indicated on the bottom graph..
570-456=114. 114/570= 20%?

Thanks
