Script field for Dashboard

[hbhardwaj3]

Hi,

I have a custom field name "Start Date" and the values for that would be D-3, D-2, D-1,D,D+1, D+2, D+3.

Here D=last date of the month. D-1 is day before last date of the month and D+1 is next day from last date of the month.

I want to use this custom field in dashboard as a bar graph indicating issue created vs and resolve on each day (from D-3 to D+3). 

How can I implement this?
