I want to create a break between subplots but would like to have the left side cover 80% of the plot and the right side 20% of the plot. I adjusted the x-axis as well to cover only the data but ideally, the plot would cover a portion of the same scale so that the data has the same stretch.

Also, is there a way to have the 2 sublplots closer to each other with a breakline in between? The .csv file with the data can be found
