How to make a StripLine appear on top of an Area Chart in Power BI Report Builder?

[Prabavathy_0108]

Hello everyone,

I’m using Power BI Report Builder (paginated reports) and added a stripline to my area chart to indicate a threshold. However, the stripline renders behind the chart’s filled area, making it invisible.

I’ve reviewed the [documentation on strip lines in Power BI Paginated Reports] which shows how to add them, but it doesn’t mention any setting to control their drawing order Microsoft Learn.

On Stack Overflow, I found this thread explaining that in SSRS/Report Builder, striplines always render in the background, and a workaround is to add another series (like a line series) with the desired threshold value Stack Overflow.

My questions are:

1. Is there a setting in Report Builder to bring a stripline in front of chart data?

2. If not, is the best practice to add an overlay line series or use another method (e.g. annotations, constant lines)?

I’d really appreciate advice or examples from others who’ve solved this in Report Builder. Thank you!

Hi @Prabavathy_0108 ,

If data labels is on, then you would see the data across x-axis for every data point. As far as reference line is concerned, to make it more visible, can you try increasing the transparency of the area chart?
This will help. 

Thank you

Hi @Prabavathy_0108 ,

You can use a Line chart instead. Create a new dataset or calculated field that returns the threshold value across your X-axis range then format the line to match your desired threshold appearance 

Ensure it appears on top by adjusting the series order if needed.

This method gives you full control over the appearance and ensures the line is rendered above the area fill.
Hope this hepls!

Thanks for the suggestion! That makes sense — using a line chart with a constant threshold dataset seems like a clean way to handle this. That works for getting the line above, but my challenge is with the data labels. Since my X-axis is dates, enabling data labels shows a label for every point. What I’m looking for is more like a reference line — with the value displayed only once, ideally at the end of the line. Is there a way to achieve that?
