How to? Upside down area plot
<p>A year or so ago I produced a hydrograph figure in Excel. This was fine at the time, but I am now at a stage where I am applying work to multiple cases, and want to easily reproduce my work from R. Therefore I'm looking to recreate this figure (or create something like this) using the graphing functions in R. </p>

<p>I am reasonably familiar with ggplot2, but the difficulty with my hydrograph is introducing the part that is coloured blue - I'm not sure if that is a) possible and if it is, b) how to do this. I believe it is essentially an upside down area plot, overlain on two quite generic and normal plots.</p>

<p>I was hoping somebody might be able to give me some help, either by saying it is possible, or giving me some pointers on how to start. It would be much appreciated!</p>
