How to add dynamic rows with an average value based on a group of rows

[lafakios]

Hi,

I would like to create a visual like the following one.

WANTED VISUAL

							Not To Be Shown
	HigherOrLowerThanAverage	ItemA 1.4	Average of the last 3 ItemA	ItemA 1.3	ItemA 1.2	ItemA 1.1	ItemA 1.0
Param1	L	0	2	1	2	3	5
Param2	L	9	14	12	14	16	12
Param3	L	1	4	2	6	4	7
Param4	H	6	3.33	3	3	4	12
Param5	H	30	20	20	10	30	14

Considering the structure of the underlying data set (can be found at the bottom of the post), a matrix visual could be used for that purpose. 

Rows	Param_id
Columns	Item_ID
Values	value

When doing so, it is not easy to add the columns highlighted in blue font color.

I have already spent some time trying to find ways to build the wanted visual. I have also experimented to pivot the param_id column in the data set. So far I have not been able to get to a solution.

Any advice or tips would be more than welcome.

Thanks in advance for your help!

Regards,

Akis

Hi,

Would the fact that no more responses have been provided mean that this is not feasible to perform in PowerBI 🙂 ?

[lafakios]

Average of the last 3 per param = {ItemA 1.3(param.value) + ItemA 1.2(param.value) + ItemA 1.1(param.value)} / 3

example: Average of the last 3 of param1 = {1 + 2 + 3} / 3 = 2

HigherOrLowerThanAverage per param = If( ItemA 1.4(param.value) >= Average of the last 3 per param, "H", "L")

example: HigherOrLowerThanAverage of param1 = L {0 < 2}

where is the item 1.4 data? I can't see in it in your sample data.

Thank you for building a PBIx report and sharing it, this actually does provide the needed functionality!

One of the key calculated columns is the below:

Column = CALCULATE(DISTINCTCOUNT('Table'[Item_ID]),FILTER('Table','Table'[param_id]=EARLIER('Table'[param_id])&&'Table'[item]=EARLIER('Table'[item])&&'Table'[Item_ID]>=EARLIER('Table'[Item_ID])))

I did a quick check if the above logic can scale to more than 4 items e.g. to support also items like itemA 1.5, 1.6, 1.7 etc. and the check result was successful.

One minor drawback of the current solution is that the column header in the visual refers to a measure name and not to the actual item represented by the measure e.g. itemA 1.4, 1.3, 1.2

The itemA 1.4 data were missing in the sample table.

Please find below the updated sample table including itemA 1.4

ItemA 1.3	Param1	1
ItemA 1.3	Param2	12
ItemA 1.3	Param3	2
ItemA 1.3	Param4	3
ItemA 1.3	Param5	20
ItemA 1.2	Param1	2
ItemA 1.2	Param2	14
ItemA 1.2	Param3	6
ItemA 1.2	Param4	3

Can you please share the logic of your calculations ? For HigherOrLowerThanAverage and Average of the last 3 ?
