Current price line doesn't always show on plot

It is difficult to quickly scan for the current price using the mouseover plot if there is a low probability of that being the price.

Nice and easy to see the current price (orange line) when the current price has some probability of occurring:

Hard to see current price when there is a low probability of that being the price (no line appears, must look at the text and compare to axis values):

Would be nice if there was a min length of the line:

Or, if the line appeared below the axis:

Current price line below the axis might be ideal, as it would never obscure a quartile line. Probably would be much more difficult to implement?
