Combo Chart: switching line label values does not work

[Fabrice_Windus]

I want to add data values in a table format at the bottom of a bar chart, using a combo chart (line and stacked column chart). To do that, I created some measures with fixed values like -1, -2, ... and added them to the line section of the combo chart.

Then, I want to change the label of these lines to show the corresponding value instead of -1, -2, ...

So I went into data labels, selected the line and changed the value to a measure which returns the value to be shown. The result? Power BI still shows -1 instead of the label measure value. I checked this using a measure TEST = 1 and this is the result:

Here is what I selected in the visual settings:

When I change the visual to a line chart, the label is shown correctly, so this seems to be a bug with the combo charts. Does anyone know a workaround? Thank you!

Hi @Fabrice_Windus ,

Yep, this is a known quirk with combo charts in Power BI — the line data labels don’t always respect dynamic measure values when combined with columns. It works fine in a standalone line chart, but combo visuals can behave differently due to rendering priorities.

Here’s a workaround you can try:

1. Instead of using fixed values like -1, create a measure that returns the actual value you want to show, but only under certain conditions. For example:

   LineLabel = IF(SELECTEDVALUE('YourTable'[Category]) = "X", [YourActualMeasure], BLANK())

1. Add this measure to the line values section.
2. In the Data labels settings, make sure:
   • Data label is turned on
   • Value is set to "Value from field" and you select your dynamic measure
3. If it still doesn’t work, try switching the chart type to line chart, set the label, then switch back to combo — sometimes this forces the visual to refresh correctly.

If none of that works, you might consider using a custom visual like Deneb or Charticulator for more control over label rendering.

Let me know if you want help building a sample measure or visual config.
