The function fitting sub-plots were automatically generated by Python through polynomial regression. The value X-axis represents the access time of a doctor, and the value of Y-axis represents department labels. The blue dots represent 79 random points distributed along the boundary line of Fig. 10. Sub-plot (a) illustrates the result of fitting with a 5th-degree polynomial. Sub-plot (b) illustrates the result of fitting with a 6th-degree polynomial. sub-plot (c) illustrates the result of fitting with a 7th-degree polynomial. Sub-plot (d) illustrates the result of fitting with a 8th-degree polynomial
