To provide a suitable recommendation for labeling the x-axis, I'll need some additional context regarding the data you are working with. Typically, in commute time and distance scenarios, you might use:
- Distance (x-axis): Measured in miles or kilometers, depending on the region or preference for measurement.
- Time (y-axis): Measured in minutes or hours.
If you can share more about the specific data you have (e.g., whether you're comparing different modes of transportation or looking at different routes), I can give you a more tailored response.
