Spark line not showing in column of table matrix

[Anonymous]

Hello everyone, I am experiencing a problem with a sparkline I setup within a column. I do not get any errors in my DAX code and I changed the value for to Image-URL. It seems like a box for the sparkline gets created for the column but there is no image in it. I wonder what could be the issue. Below is my code:

Sparkline = 
// Static line color
VAR LineColor = "#01B8AA"
// "Date" field used in this example along the X axis
VAR XMinDate = MIN(Kalender[MaandNr])
VAR XMaxDate = MAX(Kalender[MaandNr])
// Obtain overall min and overall max measure values when evaluated for each date
VAR YMinValue = MINX(VALUES(Kalender[MaandNr]),CALCULATE([Actuals2]))
VAR YMaxValue = MAXX(VALUES(Kalender[MaandNr]),CALCULATE([Actuals2]))
// Build table of X & Y coordinates and fit to 100 x 100 viewbox
VAR SparklineTable = ADDCOLUMNS(
    SUMMARIZE(Kalender,Kalender[MaandNr]),
        "X",INT(100 * DIVIDE(Kalender[MaandNr] - XMinDate, XMaxDate - XMinDate)),
        "Y",INT(100 * DIVIDE([Actuals2] - YMinValue,YMaxValue - YMinValue)))
// Concatenate X & Y coordinates to build the sparkline
VAR Lines = CONCATENATEX(SparklineTable,[X] & "," & 100-[Y]," ", [MaandNr])
// Add to SVG, and verify Data Category is set to Image URL for this measure
VAR SVGImageURL = IF(HASONEVALUE('KPI Data (2)'[Actual]),
    "data:image/svg+xml;utf8," & 
    "<svg xmlns='http://www.w3.org/2000/svg' x='0px' y='0px' viewBox='0 0 30 120'>" &
     "<polyline fill='none' stroke='" & LineColor & 
     "' stroke-width='5' points='" & Lines & 
     "'/></svg>",
     BLANK())
RETURN SVGImageURL

Hi @Anonymous ,

No, you just need to set them in measure. Please refer to https://www.w3schools.com/graphics/svg_polyline.asp

Hi @Anonymous ,

Would you please try to change the last part of your code to:

VAR SVGImageURL = IF(HASONEVALUE('KPI Data (2)'[Actual]),
"data : image/svg+xml;utf8," &
"<svg xmlns='http://www.w3.org/2000/svg' x='0px' y='0px' viewBox='0 0 30 120'>" &
"<polyline fill='none' stroke='" & LineColor &
"' stroke-width='5' points='" & Lines &
"'/></svg>",
BLANK())

Thanks for the reply, however it is still not rendering the image. I think it must be a small issue somewhere but I do not know what it could be.

Hi @Anonymous ,

Just based on my test, the code I use can render the image:

Okay, I tried your exact test code on my company laptop and personal PC and both got this broken image. I also used the image url category. Do I need to check my settings?

Hi Dedmon, thanks for the info. It seems like it helps. It looks like the image just doesn't want to render.

what's the rationale behind:

IF(HASONEVALUE('KPI Data (2)'[Actual])

 ?

Hi, I think that was a little mistake. Now I placed the category there instead.
