Histogram from a measure table

Hello,

I'm trying to create a histogram to display how the BIAS of a group is behaving.

I created a table through Power Query which can give me the information I need at the highest possible granularity, however I'd like to be able to group this information by SKU.

What I currently have is:

Information from original table @ higest granularity

Which would in turn in the grouped level be:

*Note in case of SKU 1 I use 2 as BIAS for everything with FCST 0*

When I graph this information with bins created with grouping I get this information:

Which is displaying the 14 rows shown in the highest granularity.

For the purpose of grouping the information I created a measure which returns the amount of grouped SKUs in the category:

CalcBIAS = 
VAR BinRange = GENERATESERIES ( -2, 2 , .1 )
Var TempTable =
ADDCOLUMNS(
    SUMMARIZE( 'BIAS (Baseline + FACT)', 'BIAS (Baseline + FACT)'[SKU] ),
    "BIAS", MIN(
        2,
        MAX(
            -2,
            CALCULATE(
                DIVIDE(
                    SUMX(
                        'BIAS (Baseline + FACT)',
                        'BIAS (Baseline + FACT)'[FCST] - 'BIAS (Baseline + FACT)'[FACT]
                    ),
                    SUMX( 'BIAS (Baseline + FACT)', 'BIAS (Baseline + FACT)'[FCST] ),
                    2
                )
            )
        )
    )
)

Return
COUNTX(TempTable, [BIAS])

The result of the TempTable variable is a table which only has SKU and the grouped BIAS

However, when I try to place it in the same graph the result is this:

I get a very similar graph because it's "respecting" the grouping from the original table, so I have a single appearance of SKU 1, 4 SKU 2 and 4 SKU 3 (one for each calculated bin group).

My question is:

How can I change the the axis in my chart to be a series between -2 and 2 (in .1 increments) which doesn't save the original table's relation so I can group info?
