I think I've found a trendline bug - or perhaps a feature request

[intrasight]

Hi,

I have a "Line and Clustered Column" chart
I am using DirectQuery
I added a measure
I added a "Column series" and filtered to select two series
I enabled trendline and turned off "Combine series"
So far so good - looks fine

Then I added two calculated measures to "Line values" slot.

But now I have four trend lines. I had only expected to have two.
Is this the expected behaviour with this visual? If so, I think a
good feature to have would be another binary setting to enable/disable
the trend lines for the line measures added to the chart.

hi  @intrasight 

This is a expected behaviour with this visual.

Since "Line and Clustered Column" chart are a combo chart that combine "clustered column" chart and "line chart" into one chart visul.

the trend line will apply for "Clustered Column" part and "Line" part too.

for your requirement, you could post your new idea in Power BI ideas and make this feature coming sooner .

Best Regards,

Lin
