I have a column where are written in how many miles a car needs to go to the car maintenance and I need to make a graph about it. This graph is divided between 4 columns:
Each week I receive uptade and sometimes a car go from one colum to another but there is a problem because the car is counted twice.
Do you know how I can keep only the last update of a car ?
@Thomas897 is it possible to post how your data is stored? i.e teh table view with an example of how it looks, showing a line where the data falls into both categories?
