Easy Chart Parts Per Hour

How can i turn the following code into a chart showing the parts per hour on the y and date and hour on the x. I assume i will have to combine date and hour but not sure how.

SELECT CAST(PartExtractExit as date) AS ForDate,
       DATEPART(hour,PartExtractExit) AS OnHour,
       COUNT(*) AS Totals
FROM [Thermoplastics].[dbo].[MoldingResults]
GROUP BY CAST(PartExtractExit as date),
       DATEPART(hour,PartExtractExit)
