Data Labels

The scatter plot features intelligent label placement that goes far beyond the standard Power BI scatter chart:

  • Automatic positioning — Labels are placed to minimize overlaps with other labels and data points
  • Automatic line wrapping — Long labels wrap automatically to avoid extending beyond the chart boundaries
  • Series-colored text and background — Use the Use Series Color option on text or background to instantly see which category each label belongs to
Category-Colored Labels — the readability game changer

On a dense scatter plot, identifying which point belongs to which category can be challenging. Enable Use Series Color on the label background to give each label a colored badge matching its category. This feature is not available in the standard Power BI Scatter Chart and dramatically improves readability, especially when points from different categories overlap.

Zoom Inset

The zoom inset is one of the most distinctive features of the Smart Scatter Plot. It magnifies a selected rectangular region of the chart and displays it as an enlarged inset — making it easy to explore dense clusters of points without losing the overall context.

Interactive Zoom — even in reading mode

Unlike features that only work in edit mode, the zoom inset is fully interactive in reading mode. Report consumers can explore dense data areas without any editing permissions. This makes it ideal for published reports and dashboards.

Properties

PropertyDescription
Zoom ActiveEnable/disable the zoom inset
Source X/YTop-left corner of the source region (%)
Source Width/HeightSize of the source region (%)
Inset X/YPosition of the magnified view (%)
Inset Width/HeightSize of the magnified view (%)

All values are percentages of the plot area (0–100). Because values are expressed as percentages, the zoom inset maintains its relative position and size when the chart is resized or printed at a different resolution.

Zoom Inset settings — all values in percentages of the chart area

Automatic positioning

In most cases, you do not need to set these values manually. When the zoom inset is enabled, you can drag and resize both the source region and the inset window directly on the chart. The percentage values update automatically. Manual entry is only useful when you want to replicate the exact same zoom configuration across multiple charts.

Zoom Inset in action

Without zoom, dense clusters make it hard to read individual labels:

Scatter plot without zoom — labels overlap in dense areas

With the zoom inset enabled, the dense area is magnified and labels are much easier to read:

Logo Markers

When a Logo data role is provided, the Logo marker shape becomes available in the Marker Shape dropdown. Each data point is then rendered as its own logo image instead of a geometric symbol.

  • Each point displays its own logo from the dataset — not the legend group's logo
  • Points without a logo gracefully fall back to a circle marker
  • Logo size follows the Size encoding, just like other marker shapes
  • Logos are also rendered inside the Zoom Inset when active
Per-point vs per-series logos

The Logo data role is bound per row. If your dataset has a different image for each point (e.g., country flags, product photos), each point will show its own image. If the logo column contains the same image for all points in a legend group, all points in that group will share the same logo — no extra configuration needed.

Data Colors

The Data Colors card lets you customize point colors from the formatting pane:

  • With a Legend field: one color picker per legend category
  • Without a Legend field: one color picker per point label (Values)
  • Colors set in the formatting pane override the default palette but are overridden by the Color data role (DAX measure)

Analytics (Scatter)

The scatter plot supports analytics lines on both axes. Unlike standard Power BI visuals, which allow adding multiple instances of each line type, custom visuals are limited by the API to one instance per line type. To compensate, the SDM Scatter Plot offers a Both axis option that draws the same statistic on both X and Y axes simultaneously.

  • X Constant Line / Y Constant Line — User-defined constant values
  • Min Line, Max Line, Median Line, Average Line — Each with an axis choice: X Axis, Y Axis, or Both
  • Symmetry Shading — Highlights the area where Y > X or Y < X
  • Ratio Line — Draws the Y = X diagonal
Drawing a crosshair at the average

Select Both on the Average Line to draw a crosshair at the center of mass of the data distribution. The same style, color, and shade settings apply to both the vertical and horizontal lines.

Common Properties

Each reference line has:

PropertyDescription
ShowToggle the line on/off
MeasureX Axis, Y Axis, or Both (stat lines only)
Line ColorColor of the line
TransparencyLine opacity (0–100%)
Line StyleSolid, Dashed, Dotted
WidthLine thickness (px)
PositionIn Front or Behind the points

Shade Area

Each reference line can optionally shade the area on one side:

PropertyDescription
Shade AreaEnable area shading
PositionBefore or After the line
Match Line ColorUse the line color for shading
Shade ColorCustom shade color
TransparencyShade opacity

Analytics lines are particularly useful on scatter plots to define quadrants (using X and Y constant lines), highlight performance thresholds, or identify the center of mass of the data distribution.
