Maybe you should add the volume-weighted avg to that graph too, the steep price rise is due to maybe one or few small outliers, right? form your other post: Price (volume-weighted avg / median): 1 BTC = 176.9474 / 139.2758 XMR 1 XMR = 0.00565140 / 0.00718000 BTC (avg weights larger offers more heavily; median is the middle offer rate, less affected by outliers)
