@Tini , Return the rowcount difference for a view name over available dates
Use Time intelligence along with date table, joined with date of your table
example measures
This Day =sum('Table'[rowcount])
This Day = CALCULATE(sum('Table'[rowcount]), FILTER(ALL('Date'),'Date'[Date]=max('Date'[Date])))
Last Day = CALCULATE(sum('Table'[rowcount]), FILTER(ALL('Date'),'Date'[Date]=max('Date'[Date])-1))
Last Day = CALCULATE(sum('Table'[rowcount]), previousday('Date'[Date]))
Day Intelligence - Last day, last non continous day

Problem 2: Get value of total rowcount change per view name and filter top n views with highest total rowcount change value
You can use TOPN at visual level filter or TOPN function
TOPN: https://youtu.be/QIVEFp-QiOk
TOPN with Numeric Parameter -https://youtu.be/cN8AO3_vmlY?t=26448
Create time series graph for those top n views, grouped by view name
Use a filter TOPN or use TOPN measure as filter at visual level
