Filter chart to show last 30 rows on x axis from data

[gsksarepta]

I have sql dataset that appends every week with new manufacturing data. However, I would like to show only last 30 lots of data on line charts. Can I know what are the options to get this type of filtering from the whole dataset?

@gsksarepta , if lot number is sort able the create a new column

Lot Rank = Rankx(Table, Table[Lot Number],,desc, dense) //use skip if needed

You can use filter at page level rank <=30

you can create a measure, that can use in visual or visual level filter

calculate(sum(Table[Value]), filter(Table, Table[Lot Rank] <=30) )
