Counting number of times a value appears and tallying

[Kez_nz]

Hi, I'm having a bit of trouble with DAX

Say if I have a dataset like this:

date,name
2020-05-04,Snake
2020-05-04,John
2020-05-04,John
2020-05-04,John
2020-05-04,James
2020-05-05,Liquid
2020-05-05,Snake
2020-05-06,Snake
2020-05-06,Snake
2020-05-06,Snake

I want to calculate how many times each names appears, then 'tally' those numbers. So in the above dataset, James & Liquid appeared in the dataset once, John appeared three times, and Snake appeared five times.

This is my desired output:

When using the solution from @ryan_mayu 

Column = CALCULATE(COUNTROWS('Table'),FILTER('Table','Table'[NAME]=EARLIER('Table'[NAME])))

If the dates get adjusted with a slicer, the values do not get updated (i.e. if a date slicer was set to 2020-05-05 onwards, 'Snake' would still show as appearing five times rather than four.

Thanks

@Kez_nz 

maybe you can create a column.

Column = CALCULATE(COUNTROWS('Table'),FILTER('Table','Table'[NAME]=EARLIER('Table'[NAME])))

in your sample data, john appears 3 times, james and liquid appear once and snake appears 4 times

I've went and tried it on my own data set and it worked until I changed the dates using a slicer.

I think I've found the problem: 

If I add a row so that 'Snake' appears five times instead of four:

date,name
2020-05-04,Snake
2020-05-04,John
2020-05-04,John
2020-05-04,James
2020-05-04,John
2020-05-05,Snake
2020-05-05,Liquid
2020-05-06,Snake
2020-05-06,Snake
2020-05-06,Snake

If I shift the slicer to 2020-05-05, 'Snake' should now only be in there four times instead of five. However the graph still shows it as five:

Is there any way to fix this?

I think measures can't drag to x-aixs field. Let's see if anyone else can provide better solution for you.
