What is your source?
I asked for your source (Post #922) because I didn’t know which units for natural gas were being referred to in your post (#917). 1,000 BTU, dekatherms, 1,000 Cubic Meters, megawatt-hour, etc.
This makes your chart more readily understood (for slow people as myself):
Europe’s benchmark gas prices at the Dutch TTF hub rallied 14% between Monday and Wednesday, jumping by 6% on Wednesday at a new record of $240 (236 euro) per megawatt-hour. Gas prices have already doubled since June, when Russia first reduced supply via Nord Stream, the key pipeline carrying gas to Europe’s biggest economy, Germany.
