Audit report from custom report sharepoint

I want to create a webpart in which I have 2 date fiels (start date and end date) , a button (submit) and a grid view. I want to fetch the report from "Audit log report" , run a custom report and display report based on start date and end date selected in my control fields. The report in grid will be in format like User name in Y axis and no. of view report in X axis. I want to hardcode 10 users to be displayed in Y axis.

Eg, If i select start date 15 Jan 2015 and end date as 15 feb 2015, it will display a report in grid with 10 hardcoded user in Y axis and no. of visited in X axis and show no. of times each user visited site.
