How To Use Data From Uploaded Excel File And Display Chart Based On Query

I have a graph chart and my row source type is a Query. So I retrieved data from the Query that I built.

However , I want to get the data from the uploaded excel file.

I have a form that will prompt user in the beginning to upload the excel file and replaced the old table in Access- "CrossSystemData"

Basically , I want to pull data from Excel file , Run the query(Data from excel file) then excute to "display a chart based on my query" ... Is it possible ?

Query SQL: "PolyWrongRegInsCount"

Code:
SELECT GROUPING.INSTITUTION, Count(*) AS NO_OF_GROUP
FROM (SELECT DISTINCT CATEGORY, GROUP_NO, INSTITUTION, IIF(Left(INSTITUTION,1)="P","POLYCLINIC","HOSPITAL") AS INS_TYPE FROM CrossSystemData WHERE INSTITUTION NOT LIKE "*UNKNOWN*") AS GROUPING
WHERE (((GROUPING.CATEGORY)="WRONG REG") AND ((GROUPING.INS_TYPE)="POLYCLINIC"))
GROUP BY GROUPING.INSTITUTION;

My Chart SQL :

Code:
SELECT PolyWrongRegInsCount.[INSTITUTION], PolyWrongRegInsCount.[NO_OF_GROUP]
FROM PolyWrongRegInsCount;
