Delta · Compare

The number, how it moved, and where it’s heading

The top of most reports is a row of key figures. Each needs the number, how it compares with last year or the target, and which way it’s going. In Power BI that means a stack of extra measures and conditional formatting for every card, and most KPI visuals colour gains green and losses red.

Free to use, with no watermark and no time limit. Pro from $3 per viewer a year.

What it shows

Each measure gets a tile: its name, the value in large figures, then the variance with a real plus or minus sign (“+6.9% vs 2025”, “−1.4 pp vs target”) in fjord blue when it’s better and ember orange when it’s worse. Under it, a grey sparkline shows the trend, with a dot at the end in the colour of the variance. Several tiles line up in a row or a grid of the same size.

How to set it up

Add Delta from AppSource or the .pbiviz file, then drag in:

Values
The measures to show, one tile each (up to 8).
Comparison
What each value is compared with, such as last year or a target, in the same order as Values. A tile without one shows just the value.
Trend axisPro
A date or month field for the sparklines.

In the report

  • Hover a tile for the value, the comparison, the difference and the change in percent; hover the sparkline for each point.
  • The report’s number formats, with display units that keep three digits (4.49 M€) or the units you choose.
  • A percentage measure always shows its change in percentage points.
  • Light or dark background, high-contrast mode, and your own better, worse and sparkline colours.
  • Tab into the tiles and move with the arrow keys. Screen readers hear each tile as one sentence.
  • The format pane and messages are in English and Norwegian.

Free features always work, with no key and no tag. Pro features need a licence key for Delta or Everything. Without a valid key, Delta shows the first tile without its sparkline, with a short notice and a “Try Pro free” button. A paid key keeps Pro working for 7 days after it runs out, so a late renewal never breaks a report.

Your data stays in your report

Delta makes no network calls and stores nothing outside the report. The licence key is checked inside the visual, so it also works offline, in Report Server and in locked-down tenants.
