no this is Because two reasons
1) huge spam that happen after 11/11 it was full block size fee(1000 sat) that will make chart up .
2) huge increase of bitcoin price from 1,000$ to 8,000$ that much fee increase.
now coinbase and blockchain.info will support 2x which will make number of fee reduce fast in future and when price stable also fee when be down so dont worry
your chart is wrong (cost of fee which is increase because price) this is real chart
