September 2021 Power BI Update
Part four of a seven-part series of blogs

The September 2021 update to Power BI introduces even more features for customising buttons, a Power Automate connector and line chart series labels, along with a few other small changes.

  1. September 2021 Power BI Update
  2. You can use shapes and icons as buttons
  3. Running Power Automate flows from Power BI reports
  4. You can now label line chart series (this blog)
  5. Suppressing totals on waterfall charts
  6. Changes to DAX
  7. Pictorial histograms using the Graphomate custom visual

We've been creating our idiosyncratic monthly blogs on Power BI updates since November 2016, and also deliver online and classroom Power BI courses.

You need a minimum screen resolution of about 700 pixels width to see our blogs. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.

You can now label line chart series

Pleasingly, you can now show labels for the lines of a line chart:

Line chart series labels

The series labels can have a foreground and background colour.

Here are the Series labels settings used for the above chart:

Series label settings

The colour scheme isn't necessarily one I'd recommend!


You can choose to have different label formats for different lines by customising your series:

Custom series

Toggle this option to customise your series labels.


Here's an example:

Desert label

Here we're trying to make the Desert label stand out.


And here's what this would look like:

Different label

The label now stands out.


Does anyone else think it's strange that the series label colours don't default to the corresponding legend colours?
