I want to build a graph using linear data across different time points. The data is 8 weeks apart and consist of the same variable. However, my first two time points are on the same day. I want the first two data results to be slightly apart to be readable and not the same increments as the other data to avoid it being interpreted as 8 weeks apart. The variable in the dataset is collected across many years so the data entries for each time points are not collected on the same day.

Time points "0-B" and "0-I" are on the same day (week 0). All other inputs are 8 weeks apart.
Is it possible to modify the X-axis to have the first two points close together and keep the rest of the time points equally separated as they are in the shown graph?
