Hm, something looks a bit weird about the new line chart with median price:
a) how do you calculate median price? it should be high+low/2, but it looks as if it is maybe "typical price" which is high+low+close/3.
b) the red/green area below/above the line should mark the lowest/highest price of the period, right?
Like I said, something looks a bit strange to me, either a) or b) (or both) are different that how I think they should be.
I'm sorry, I made a mistake, the median price algorithm was incorrect, now the bug has been fixed.
Sorry to be a pain in the ass, but... not sure if it's fixed. It took 2 screenshots to show what I mean:


First, the green/red area seems to be correct, it corresponds exactly to the highest/lowest part of the candles.
But the median price itself still isn't right: In the first pic, time: 2013-10-17, 3:00. Based on the candle data, the median is 137.25. Second pic, the median as displayed by the line is 138.63.
By the way, I reloaded the page/got rid of cache to make sure I got the updated version of your website.
