Shade with different colors portions of figure based on data

Hello,

Wondering if anyone could help me with this...

I do have a time-series (Data attached) with positive and negative values and want to create a similar figure as the one below (it was created using R). Looking to do the following:

Plot data having x = Data attached (column 1) vs y = Data attached (column 2)

 1) Plot time-series with red dots for values >0 and blue dots for values <0 
 2) Add a background color and be able to choose transparency
 3) Add a red vertical band, on background, to data >=1.5 and be able to choose transparency
 4) Add a blue vertical band, on background, to data <=1.5 and be able to choose transparency
 5) Add the trend of the positive values as a red line
 6) Add the trend of the negative values as a blue line

Thanks!
