Scatter plot of expenditure percentiles between two consecutive time periods for different period lengths. The upper right corner is denser, implying the HCHN patients are more temporally consistent. From left to right, x axis are the last month, last 3 months, last 6 months, and entire 12 months of 2012 respectively. The y axis are the first month, first 3 months, first 6 months, and entire 12 months of 2013 respectively
