Shift your mindset: A histogram is a statistical X-ray of your data — not just a bar chart.
1
0–1 min

Get started in seconds

Drag any numeric field into the Values field well. The histogram renders instantly with 10 bins, mean, and median lines.

  • Numeric field in Values
  • Category (optional) for cross-filtering
  • Tooltips (optional) for extra measures per bin
2
1–3 min

Read the shape of your distribution

The gap between μ (mean) and M (median) reveals skewness. Close together = symmetric.

μ ≈ M → Symmetric  |  μ > M → Right-skewed

Tune the bin count for more detail

With a Pro license, set bins from 2 to 100 to control resolution.

  • Fewer bins → overall trend
  • More bins → micropatterns and gaps
  • Rule of thumb: √n bins for n rows

Detect and handle outliers

Use Lower / Upper trim % to exclude extremes without touching the data model.

  • Trim 2% on each end for sales data
  • "n trimmed" counter appears in the stats panel
  • Original data is never modified

8–12 min · Pro

Validate normality with the curve

Enable the normal curve to overlay the theoretical distribution. Do the bars follow it?

  • Good fit → statistical models are valid
  • Bimodal → two distinct segments in your data
  • Long tail → significant outliers present
6
12–15 min

Avoid common mistakes

  • Too many bins with a small dataset
  • Ignoring the gap between μ and M
  • Not trimming when extreme outliers are present
  • Enable the stats panel for full context
  • Add a benchmark line for your SLA or target

Key benefits
Instant analysis
From a numeric field to a full distribution with statistics in seconds — no extra DAX needed.
See what averages hide
Bimodality, long tails, and outliers that a mean value would never reveal.
Native cross-filtering
Click a bar to filter the entire report page. Full Power BI integration.
Executive-ready
IBCS mode for financial reporting. Value labels for presentations without hovering.
Key takeaways
Always add the Category field if you want cross-filtering to work with other visuals.
If μ and M are far apart, check for outliers before drawing conclusions.
Use Lower/Upper trim % to present the core distribution without distorting extremes.
Combine the normal curve with the stats panel (σ) to validate statistical assumptions.
Add a Benchmark line with your SLA or target value for immediate context.
Learn the pattern once. Apply it to any metric. Works equally well for sales, lead times, scores, or margins.
