You need to be explicit on what you want. What are 'all the values'? Speed and Size are the same for all records so does it make sense to graph those?
BatchTime would be the X axis values and then Temp would be Y axis? Provide a mockup image.
A RowSource could be:
SELECT [Batch Time], [T1_Temp(C)] FROM table WHERE [Batch No]=[enter batch number];
If you want multiple batches then try:
TRANSFORM First([T1_Temp(C)]) AS [T] SELECT [Batch Num] FROM [Batches] GROUP BY [Batch Num] PIVOT [Batch Time];
Advise not to use spaces nor punctuation/special characters in naming convention. Better would be T1_Temp_C.
