The question is not clear. What is the relation between the "reference values" and DX, DY? Did you mange the import from Excel already? How o you want to "show" the results?

thank you for your time. refernce values are X,Y values. and i have a excel sheet which has 127 rows and 127 columns and all rows and columns contains some values [suppose calculated]. i need these calculated values of the refernce X,Y values.
