Getting started

1
Question · Response · Value. One row per question × scale point, with the count in Value.
2
Scale order. The numeric rank of each point, 1 = leftmost.
3
Group [Pro]. Draws the questions as labelled blocks with their mean.
⚠ Scale order is not optional in practice

Without it Power BI hands the responses over alphabetically — Agree, Disagree, Neutral, Strongly agree… — which is not a scale. The visual cannot detect that, so it would draw it wrong without saying so.

The free tier is correct, not cut down.

No question, scale point or respondent is hidden, and nothing is watermarked in a published report. Pro adds the analyst readings on top.

While you edit without a licence, Pro features render working under a “Pro preview” watermark. Reading view shows the free result, with no watermark.

Pro includes a one-month free trial.
