Custom Tooltip on Matrix Based on Measure

[cristianpark]

Hi guys

I'm trying to do something somehow easy but it seems like is not possible in Power BI (Jan 2020 release). I'm trying to display a help message (on a tooltip) based on column the user is hovering into.

There are two different measures (Fixed and Available) and a dimension (Type) used in order to achieve this

I want to display text when user hovers on a cell (column based):

• When hovering on Fixed values: Fixed values are for vehicles that entered reparation during last month and got fixed already.
• When hovering on Available: Available % indicates proportion of vehicles ready to sell for each type.

I'm trying with this DAX expression in order to determine whether I'm in Fixed or Available column

Tooltip Text =
VAR selectedType=SELECTEDVALUE(Types[Label], BLANK())
VAR selectedMeasure=SELECTEDMEASURENAME()
RETURN
IF(selectedType<>BLANK(),selectedType, "Nothing")&" Measure: "&selectedMeasure

But I get error "There is no measure reference in the current context that can be used by SELECTEDMEASURENAME", I read about calculation groups and is not what I'm trying to do here but have no other clue on how to achieve this.

Could you please give me an idea on how to create such a tooltip?

Thanks

Hi , @cristianpark 

Try steps as below:

1.create a table contain a column as below

2. Then create measures "value" (to instead the field "fixed" and "available") ,and put it into the value of matrix 

Value = SWITCH(SELECTEDVALUE('Column'[Column]),"Fixed",AVERAGE('Table'[Fixed]),"Available",AVERAGE('Table'[Available]))

3.create page3 as  tooltips page ( make sure the type of tooltip is report page)

Put  measure "tooltip text" into a card visual in page3

Tooltip Text = 
VAR selectedType=SELECTEDVALUE('Column'[Column], BLANK())
RETURN
IF(selectedType<>BLANK(),selectedType, "Nothing")&" Measure: "&[Value]

4. it will show as below

Here is a demo .

Hi there,

By chance you still have the .pbix file? seems to be gone

Thank you @Greg_Deckler and v-easonf-msft for such complete answers.

Bookmarks approach @Greg_Deckler proposed is an easy way to do it without affecting underlying data model (the default option for us was just to put help text below table so bookmarks are a good addition to it).

Creation of table as v-easonf-msft is cool, that way you can customize tooltip as needed and is more scalable modifying value measure for adding columns with custom tooltip. The only caveat I saw is that you'll loose ability of sorting by each column on matrix and in my case, that's a must.

It'll be great to be able to somehow identify a measure within a cell but workarounds are good enough for now.

Thank you!

Well here is one way that I recently came up with (attached). I'll see if I can come up with anything better.
