How to hide blanks in a matrix visualization with hierarchical rows - powerbi

I've built a table of data following this helpful guide:
https://www.daxpatterns.com/parent-child-hierarchies/
I'm following it exactly but I'll still explain things here so you don't have to go through the whole article if you don't want to. I have a table of Names with corresponding keys, and ParentKeys forming hierarchies.
I added a column for the path, columns for each level of the path, depth of hierarchy and an IsLeaf column:
If I want to make a matrix and include City (from another table), all hierarchies will expand to the maximum length, and blanks are filled in with the "parent's" name:
The DAX Patterns website explains how to get around this. First add these two measures:
BrowseDepth = ISFILTERED (Nodes[Level1]) + ISFILTERED (Nodes[Level2]) + ISFILTERED (Nodes[Level3])
MaxNodeDepth = MAX (Nodes[HierarchyDepth])
And then you can factor that into calculations with this measure:
Sales Amount Simple =
IF (
Nodes[BrowseDepth] > Nodes[MaxNodeDepth],
BLANK (),
SUM (Transactions[Amount])
)
If this is the only value on a matrix visual, it turns out fine:
But if I add any other values, I get expanded hierarchies and blanks again:
My problem would be solved if I could filter out blank values, but that filters out the entire hierarchy. Do I have to make a measure using the Sales Amount format above for every value I want to include? I'm trying to add things like addresses that can't be aggregated.

Basiacally yes, you have to re do the measure. However you can embed existing into this patern which makes it a little easier.

Conditionally format a table based on average of dataset, but adhering to slicer selections

I have a simple CSV data set such as this.
ID,MainCategory,SubCategory,Type,Value
1,E,E1,Demo,5
2,N,N3,Install,2
3,E,E1,Demo,4
4,E,E2,Install,7
5,D,D1,Install,3
6,S,S2,PM,4
7,N,N2,Install,7
8,N,N2,Demo,1
9,E,E2,Demo,2
10,D,D2,Install,6
11,D,D3,PM,4
12,S,S1,PM,8
13,N,N1,Install,5
14,S,S3,Install,8

In my Power BI Desktop, I'd like to load this into a table, and conditionally format the Value column based on whether the value in each row is greater than or less than the average for the currently selected data set.
For instance, the average of Value considering the entire table is 5.08, so if there are no filters applied (as in, all my slicers are set to select nothing), I'd like all rows whose Value is 6 or more to be background colored in one color, and the others in another color. For this, I created two measures like so:
AvgOfVal = DIVIDE( SUM(G2G[Value]), COUNTA(G2G[ID]) )
BGColor = IF(SUM(G2G[Value]) > [AvgOfVal], "Light Pink", "Light Blue")
Then I tried to apply the BGColor measure for conditionally formatting the background, but this doesn't work as expected, and instead produces the result below.
I realize that this is due to the fact that the measure is calculated per row, so when conditional formatting is applied, as seen in the AvgOfVal column in the table, it calculates average per row instead of for the entire data set. How can I calculate a measure that takes into account the entire data set (considering slicers), and do the conditional formatting as I need.
Please keep in mind that if a user were to select a slicer filter (say, MainCategory = D), then I want the conditional formatting to reflect this. So in this case, given that AvgOfVal = 4.80 for MainCategory = D entries, I'd like all rows whose Value >= 5 to be in one color, and others in another color.
I realize that this is due to the fact that the measure is calculated per row
Yes. The key is understanding how that happens. When the measure is calculated a "context transition" happens and the current row is added to the filter context.
So what you want is a calculation that removes the row filter that was added in the context transition. So you need ALLSELECTED(), which does precisely that. eg
AvgOvVAl = CALCULATE( AVERAGE('data'[Value]), ALLSELECTED() )
Removing the "innermost" filter which in this case is the filter on the row, but leaving all other filters, ie filters added on the report, page, visual, or filters coming from interactions with other visuals like slicers.

Is there a way to calculate a percentage over the grand total while keeping more than one filter set?

I’m wondering if there is a way, in a table, to calculate the percentage over a grand total.
I think this is a fairly simple issue, but I really can't wrap my head around it.
I have a table with a count, divided into different Categories:
I also have several slicers:
What I would like the table to show is the percentage of the current selection over the grand total, while keeping at least other two filters set (the Year(Anno) and another one set on the entire page).
If I select in the slicer “Range Scostamento %” a value, the table will obviously update the numbers:
The value I’m looking for is the “weight” in percentage of the filtered values over the total value.
So for example, for the first row I will have 317/14.793 = 0,0214 = 2,14% and so on.
I think my question has something to do with the SELECTEDVALUE/ALLSELECTED, maybe KEEPFILTERS, but I really don’t know how to make it work.
Thanks in advance!

If I understand your requirement correct, you need these below measures for your purpose-
contratti = count(table_name[column_name])
grand_total =
CALCULATE(
count(table_name[column_name]),
ALL(table_name)
//-- ALL will return count of entire table
//-- you can use ALLSELECTED if you wants the
//-- grand_total for filtered data based on slicer
)
percentage = [contratti] / [grand_total]

Frequency Counter

Good evening everyone, I'm having trouble resolving the following question:
I have "Table 1" containing the occurrence records and "Table 2" containing the occurrences.
I need to set up a VIRTUAL TABLE or VIEW TABLE that presents the occurrences and their frequencies as follows:
Tables with Perspective
The most I could do was bring the occurrences with the total number of rows in the table, ie the same amount X for all.
Last try using DaxStudio
You need to create a measure to show the numbers in the report.
But first, it is recommended to transform the table into a form like below, where each occurrence appears in each row. This has a lot of advantage to make the DAX measure simpler, more accurate, and run faster.
This can be easily achieved using Power Query Editor. The required steps are,
Select the comma delimited occurrences column.
In Transform tab, click Split Column and choose By Delimiter.
Make sure Comma and split at Each occurrence of the delimiter is selected by default.
In Advanced options, select split into Rows, then click OK.
Then you can define a measure to count the number of occurrences, which is as simple as below.
Count = COUNTROWS ( Tabela1 )
Now, in the report area, you can use the measure to obtain the desired output.
I have recreated your tables and here is the DAX for Table3 (perspectiva):
Table3 =
VAR uniqueOccurences = DISTINCT(Table2[Occurence])
RETURN
ADDCOLUMNS(uniqueOccurences,
"count",
VAR currentOccurence = [Occurence]
RETURN
CALCULATE(COUNTA(Tabel1[ID]),
FILTER(Tabel1, CONTAINSSTRING(Tabel1[Occurences], currentOccurence) = TRUE()))
)
This returns the following table:
Please mark this as the solution if this answered your question :)

Refer to slicer-filtered table in DAX calculated column

I'm beginning to think that what I'm looking for isn't actually possible.
I have two datasets - one of Titles and one of Keywords. Only one column from each is relevant to this query - Titles[Title] and Keywords[Keyword]. So pretty straightforward data. Titles has around 2 million rows, and Keywords will eventually have ~500-1000.
I would like to display a slicer of Keywords[Keyword] values, which will filter the Titles dataset where Titles[Title] contains one of the selected Keywords[Keyword] values.
I tried creating a DAX calculated column on Titles like below -
Matches = IF(SUMX(FILTER('Keywords','Keywords'[Keyword] <> ""),FIND(UPPER('Keywords'[Keyword]), UPPER(Titles[Title]),,0)) > 0,1, 0)
I then apply a report level filter for Matches >= 1. This works for all keyword values, but is not aware of the selection in the slicer.
I tried changing it to use ALLSELECTED('Keywords'[Keyword]) as the first argument passted to FILTER, but this doesn't seem to have any effect.
As a test, I created a Calculated Column and a Measure with the exact same DAX -
CONCATENATEX(VALUES(Keywords[Keyword]), Keywords[Keyword], ",")
This displays the slicer selection delimited by commas for the measure, but not for the column. Since I want to calculate this per row and filter the report based on this, a measure isn't suitable.
Is there any other way I can refer to the filtered Keywords[Keyword] in my calculated column? Or is there a way that a Measure could actually be used to achieve this? Or is there a completely different approach that I could try?

power BI diaplay one value

I am using Power BI to bring together data from several systems and display a dash board with data from all of the systems.
The dashboard has a couple of filters which are then used to display the data relating to one object across all systems.
When the dashboard is first loaded and none of the filter have been selected, the data cards display information from all rows in the table.
Is there a way to make a data card only display one row of data?
or
Be blank if there are more than one row of data?
There's no direct way to look at the number of rows in the visual, count them, and do something different if there's more than 1.
That said, there are a few things you can do.
HASONEFILTER
If you have a specific column in your table that, when selected, filters your results to a single row, then you can check if there's a filter on that column using HASONEFILTER. (If you have multiple alternative columns,any of which filter to a single row, that's ok too.)
You could then create a measure for each column that tests HASONEFILTER. If true, return the MAX of the column. (The reason for MAX is because measures always have to aggregate, but the MAX of a 1-row column will be the same as the value in that column.) If false, return either BLANK() or an empty string, depending on your preference.
E.g.
ColumnAMeasure = IF(HASONEFILTER(Sheet1[Slicer Column]),MAX(Sheet1[COLUMN A]), "")
ColumnBMeasure = IF(HASONEFILTER(Sheet1[Slicer Column]),MAX(Sheet1[COLUMN B]), "")
where Sheet1 is the name of the table and "Slicer Column" is the name of the column being used as a slicer
HASONEVALUE
If you have multiple columns that could be used as filters in combination (meaning that having a filter applied on "Slicer Column" doesn't guarantee only 1 row in the table), then rather than testing HASONEFILTER, you can test HASONEVALUE.
ColumnAMeasure = IF(HASONEVALUE(Sheet1[COLUMN A]),MAX(Sheet1[COLUMN A]), "")
ColumnBMeasure = IF(HASONEVALUE(Sheet1[Column B]),MAX(Sheet1[COLUMN B]), "")
Notice that HASONEVALUE tests the current column you're trying to display, rather than a slicer column like HASONEFILTER.
One side-effect of HASONEVALUE is that, if you're filtered to 3 rows, but all 3 rows have the same value for column A, then column A will display that value. (Whereas with HASONEFILTER, column A would stay blank until you're filtered to one thing.)
Low Tech
Both answers above depend on a measure existing for every column you want to display, so that you can test whether to display a blank row or not. That could become a pain if you have dozens of columns.
A lower-tech alternative is to add in an additional row with blanks for each column and then sort your table so that that row always appears first. (And shorten your visual so only the top row is visible.) Technically the other rows would be underneath and there'd be a scrollbar, but at least the initial display would be blank rather than showing a random row.
Hopefully something here has helped. Other people might have better solutions too. More information:
