# Use the Radar slide
> Radar turns your audience's ratings into a live spider chart, so the whole room can score the same few criteria and see the shared picture take shape.
When you want a quick read across several areas at once, a single poll only tells you part of the story. Radar asks everyone to score the same handful of criteria on their phone, then plots the room's average for each one on a spider chart. Strong areas stretch towards the rim, weak spots pull in towards the centre, and the gaps are obvious at a glance. Nothing is scored and there is no leaderboard.
## How it works
Each spoke of the chart is a **dimension**, one criterion you want rated (for example "Communication" or "Ease of use"). Participants rate every dimension on the same scale and submit once. The presenter chart plots the **average** for each dimension and updates as more ratings arrive.
You can also compare up to three **subjects** on the same axes, such as two product ideas or this quarter against last. Each subject draws its own coloured outline, so the shapes overlap and the differences stand out.
## How to create a successful Radar slide
In the editor, click **New slide** and select **Radar** from the **Unscored** section of the slide type picker.
Type your question into the slide's title field, for example *"How is our team doing this quarter?"*. You can also upload an image and choose whether it sits to the **Left** or **Right** of the chart with **Image position**.
Under **Rating dimensions**, list between 3 and 8 criteria, up to 24 characters each. Use **Add dimension** for more. Five or six short, distinct labels read best; if two dimensions mean nearly the same thing, merge them.
Under **Suggest with AI**, describe a topic (for example *"our new mobile app"*), choose how many dimensions you want, and click **Generate**. Once you've edited the list, the button becomes **Replace**, and its drop-down arrow lets you add more dimensions to the list instead of overwriting it. If your topic names two or three things to compare, AI fills in the subjects too.
Under **Subjects**, name what's being rated and click **Add subject** to compare up to three side by side. Leave a single subject for a straightforward one-shape chart.
Under **Rating scale**, choose **1–5**, **1–10** or **0–100%**. The scale applies to every dimension. Pick 1–5 for a fast gut check and 1–10 or 0–100% when finer differences matter.
### Customising the chart
Open **Advanced** at the bottom of the settings panel to change how the results look:
* **Reveal pattern** — choose how the shape animates in: **Bloom**, **Crystallise**, **Pinwheel**, **Vortex** or **Radar sweep**. Motion, timing, direction, order and reveal front can be fine-tuned under **Reveal**.
* **Rating flow** — shown only when you compare two or more subjects. **One dimension at a time** puts every subject on the same page for each criterion; **One subject at a time** shows all dimensions for one subject, with a **Next** button to move on to the next subject.
* **Grid shape** — the rings behind the chart: **Polygon**, **Circle** or **None**, plus a **Ring style** of **Plain**, **Zebra** or **Hidden** when a grid is shown.
* **Hollow centre** — leaves a gap in the middle instead of meeting at a point.
* **Scores** — shows each dimension's average as a number on the chart, styled as a **Chip**, **Colour** or **Muted**.
## Presenting
Click **Preview** in the top header to try the presenter chart and the participant rating screen side by side before going live. When you present, participants join at the access code on screen.
On their phones, participants rate each dimension, can tap **Preview my chart** to see the shape they're about to send, then tap **Submit rating**. The chart on the big screen animates in with the first rating and settles into the room's averages as more come in.
## Where Radar works best
### Meetings and retrospectives
* **Team health check** — rate *Communication*, *Workload*, *Clarity of goals*, *Collaboration* and *Morale* on 1–5, then talk about the spoke that pulls in furthest.
* **Retrospective** — compare *This sprint* against *Last sprint* as two subjects to see what improved.
### Training and workshops
* **Skills self-assessment** — learners rate their own confidence on each skill at the start of a course, then again at the end.
* **Session review** — close a workshop by rating *Content*, *Pace*, *Relevance* and *Trainer* on 1–10.
### Product and events
* **Product feedback** — let AI suggest criteria for *"our new mobile app"* and have beta users rate each one.
* **Supplier or venue scorecard** — overlay up to three options as subjects and let the room compare them on the same criteria.
## Radar vs. Rating Scale
Both collect ratings across several statements. A [Rating Scale](/using-slide-types/how-to-use-rating-scale-slides-on-ahaslides) slide shows how responses spread along each statement's scale, which suits detailed survey-style feedback. Radar combines every average into one shape, which suits spotting strengths and gaps at a glance or comparing up to three subjects on the same criteria.
## Frequently asked questions
### Is Radar scored?
No. Radar collects opinions, so there are no correct answers, no points and no leaderboard.
### Do participants have to rate every dimension?
No. If someone submits with dimensions left unrated, they're asked to confirm before sending. Each dimension's average is calculated only from the people who rated it.
### Can I change the dimensions after people have responded?
No. Once the first rating arrives, you can't add, remove, reorder or rename dimensions or subjects, and you can't change the scale. This keeps the chart accurate. The only way to change them is to [reset the results](/after-the-presentation/resetting-the-results), which clears every response collected so far. Display options under **Advanced** stay editable.
### Why does the chart show only outlines when I compare subjects?
Filled shapes would hide each other when stacked, so a chart with two or three subjects draws each one as a coloured outline with a legend.
### What does the 0–100% scale start from?
The 1–5 and 1–10 scales start at 1. The 0–100% scale starts at 0, so it works well for percentage-style answers such as *"How confident are you?"*.
