Show Last 7 Records using Order By with Sub Query in SQL Server

By following tutorial : http://www.aspforums.net/Threads/209868/How-to-dispaly-Multi-Line-Chart-using-jQuery-Chart-plugin-in-ASPNet/

I provided a chart in my page , but there is a problem

I would like to show last 7 inserted records in my chart from left to right.

I use ID for “ORDER BY” but as number of ID started from 1 to .....

I could not show data left to right and the data shows in my chart from right to left,

The Query : SELECT TOP 7 SUBSTRING(DATENAME(MONTH,[Time]),0,4)+CONVERT(VARCHAR(10),DATEPART(DAY,[Time])) Day,Total FROM [PL-PK] ORDER BY Id DESC

Attach of my table : https://i.imgsafe.org/3934716103.jpg Attach of chart :

I think a sub query is needed, I tried something but without successful.

Your help would be appreciated
