I have a csv file of orders from a business I run the web shop for, around 30 thousand entries total. I would like to FIND all entries which have a duplicate in the base: same customer, same total due amount and placed on the same day (some customers make repeating orders but over longer timeframe).

I found a help article regarding removing duplicate values, but it doesn't really apply to my situation, because I want to remove UNIQUE values.

How would I go about that?

[Solved] Use date format for the dates and use the xy scatter plot

I have the dates and weights for the times I was weighed at my doctor's office. I would like to plot those so that the actual slopes are visualized.

I tried just putting the numbers in two columns and plotting them with a line plot but the days between the dates are irregular, sometimes 3 or more months elapse, sometimes only a week or two, but the dates on the graph are evenly spaced.

Is there a setting that will space the dates out to account for the number of days between dates, so I can see how well my diet is working?
