The -axis refers to the symptom-herb frequency. In (b), the -axis represents the 6,085 syndrome-herb patterns, ordered by descending syndrome-herb frequency. The -axis refers to the syndrome-herb frequency. In (c), the -axis represents the 7,897 symptom-syndrome patterns, ordered by descending symptom-syndrome frequency. The -axis refers to the symptom-syndrome frequency.
