Problem in doing Dynamic Segmentation of the data

Hi, I have the data of Employees and their Credit Card spends. The data contains Employees having multiple spends in the same month. 

Sample of the dataset is provided below, 

My requirement is to analyzie people who have used the Credit Card more than one time. 

I created a What-If parameter "Credit Card Used Filter" as a decimal number from 1 to 4 and added it as a slicer. I further used it in my measures so that the slicer works properly when used. 

This is how my report looks at the moment, 

However, what I am trying to do is basically create a Bar Graph that will show "Credit Card Used" in the X-Axis (that is, 1, 2, 3 etc.) 

and then show a bar containing the number of employees that fall in those categories. For example, 4000 people used Credit Card only once, 200 used it 2 times, 50 people used it 3 times, 4 people used it 4 times and maybe one more thing that we can add is -> 3 people used it 4+ times.

So what I need in my X-Axis is: 1, 2, 3, 4, 4+ 

What I need in my Y-Axis is: Total Employees falling in that category for the given set of filters (Year, Month, Department etc.) 

Thanks to TomMartens, I ended up looking into Dynamic Segmentation and tried to implement the required. I came up with the following DAX but for some reason, it is not giving me any results. And I am failing to understand the reason behind this, 

Employee Segments = 

VAR EmployeesInSegment = 
    FILTER(
        ALLSELECTED(Spending_Data), 
        VAR Emp_Count = COUNT(Spending_Data[Emp_ID])
        VAR SegmentForEmp = 
            FILTER(
                'Credit Card Use Values', 
                'Credit Card Use Values'[Value] = Emp_Count
            )
        //VAR IsEmpInSegment = NOT ISEMPTY(SegmentForEmp)
        RETURN SegmentForEmp
    )

Var _Result = 
    CALCULATE(
        COUNTROWS(Spending_Data),
        KEEPFILTERS(EmployeesInSegment)
    )

RETURN _Result

Anyone here who can help in achieving this? Thanks.
