can you provide some sample data?

what is the order it should go in?  date?  how do you sequence these values?

in theor you need to;

1. create each line as a measure

2. then and substract line 1 - line 2 as another measure

3. plot the category on the x axis and the lines on the y axis as per your 

and then one frrom the other and plot it on the line chart.  you will need to play with the formatting a bit.
