Issues with Scatter Chart and Slicer

[WeiKeongTan]

Hi, 

I would like to create a scatter chart in Power BI to visualize the spatial locations of semiconductor die based on their X and Y coordinates. The goal is to enable dynamic highlighting of specific dies based on the user interaction - QRTAG_U1.

The scatter chart should display all die locations (X vs Y) regardless of user selection. A slicer should allow users to select one or more values from the QRTAG_U1

By default, all die should be displayed in blue. When user selects one or more QRTAG_U1 from the slicer, die associated with the selected QRTAG_U1 should appear in red and all other die should remain in blue.

I’ve created a DAX measure for conditional formatting to change the color of points in a scatter chart based on the selected QRTAG_U1. However, when a QRTAG_U1 value is selected, only the points for that selection appear in red, and the other die locations do not remain visible in blue. May I know how can we enable the scatter chart to keep all other die locations displayed in blue while showing the selected QRTAG_U1 points in red?

DieColor = 
VAR _SelectedQRTAG = SELECTEDVALUE('wafer'[QRTAG_U1])
VAR _CurrentQRTAG = MAX('wafer'[QRTAG_U1])
RETURN
    IF (
        HASONEFILTER('wafer'[QRTAG_U1]), 
        IF (
            _CurrentQRTAG = _SelectedQRTAG,
            "Red",
            "Blue"
        ),
        "Blue"
    )

I have uploaded the sample data here:

Thanks for any assistance!

Hi:

One of the workarounds is to create one disconnected table for ORTAG_U1 slicer, 

QRTAG_U1_Slicer = VALUES(wafer[QRTAG_U1]).

Then for the conditional formatting on die color, if you wanted to highligh single die in red, you can use this below, 

Die_Color1 =

VAR _SelectedQRTAGs = SELECTEDVALUE(QRTAG_U1_Slicer[QRTAG_U1])

RETURN

IF (

    MAX(wafer[QRTAG_U1]) = _SelectedQRTAGs,

    "Red",

    "Blue"

)

If you would like to multi-highlight dies in red, you may use this measure below:

Die_Color2 =

VAR _SelectedQRTAGs = VALUES(QRTAG_U1_Slicer[QRTAG_U1])

VAR _HasSelection = ISFILTERED(QRTAG_U1_Slicer[QRTAG_U1])

VAR _CurrentQRTAG = MAX(wafer[QRTAG_U1])

RETURN

IF (

    _HasSelection && CONTAINS(_SelectedQRTAGs, QRTAG_U1_Slicer[QRTAG_U1], _CurrentQRTAG),

    "Red",

    "Blue"

)

Thanks

Thanks, Mason! I tried the workaround, and it works perfectly. Really appreciate your guidance!
