The ridgeline plots present the distribution of 20 regional variation features in three different cancer types. Here, we investigate 2 tumour regions, tumour core (TC) and tumour invasive margin (TIM), plus 2 peritumour regions, parenchymal margin at 5 mm or 10 mm (PM5 or PM10). In total, 5 pair-wise regions are considered, namely, TC-TIM, TC-PM5, TC-PM10, TIM-PM5, TIM-PM10. Variation for each pair-wise region was quantified with four measures (chi-square, Bhattacharyya distance, correlation, intersection), yielding 5*4 = 20 regional variation features. TC-PM5 and TC-PM10 related features are colored in green, while TIM-PM5 and TIM-PM10 related features are colored in blue.
