Scatter Plot with a Rolling Average Line in Power BI

Hi Anonymous ,

You can use a Line and Scatter Chart (or Combo Chart) to overlay:

Scatter plot of raw X vs Y values
Line plot of average Y per X-bin

Here are few Steps to Implement:
Create Bins for X-Axis (In your case bins are already created).

Right-click your X-axis field - New Group
Choose Bin Type: Number of Bins (e.g., 10)
Create a Measure for Average Y per Bin:

AvgY_PerBin = AVERAGE('Table'[Y])

Create a Line and Scatter Chart or Combo chart:
X-Axis: X (for scatter) and X_bin (for line)
Y-Axis:
Raw values: Y (scatter)
AvgY_PerBin
