Customize Threshold

Customize Threshold

Hi
On a report I have 2 Thresholds that appear very close together (I will be doing many reports where this occurs). I have attached an example of how the report looks if I just use the standard setup. Is there some way I can customize this so that the appearance is better. (e.g. have the test for the lower threshold appear below the threshold line)  I am happy to use coding is needed.  
Thank you
Gill
