What is a half donut chart maker?

A half donut chart maker lets you create a semicircle ring chart, a 180° arc with a hollow center. The segments fan across the top half, and the center space below the arc is used to display a headline metric, percentage, or KPI label. AECharts lets you paste data, customize colors and center text, and export and use in PowerPoint or Google Slides.

What is the difference between a half donut chart and a regular donut chart?

A regular donut chart is a full 360° ring. A half donut chart uses only the top 180°, a semicircle arc. Both have a hollow center for a headline metric, but the half format is more compact, fits better in wide dashboard panels, and has a natural flat baseline that anchors it visually in a slide or report layout.

What is a half donut chart used for?

Half donut charts are best for gauge-style KPIs, single percentages, and 2–3 category splits where the center metric is the main message. Common uses: goal completion, quota attainment, progress toward a target, and portfolio or budget splits where the total belongs center stage.

Can I add a metric to the center of the half donut?

Yes. The hollow center below the arc is the natural home for a percentage, total, or short label. In AECharts you can customize the center text, font, size, color, to match your chart style.

Can I import data from Excel or Google Sheets?

Yes. Copy your data and paste it directly into the editor. Format: one column for category labels, one column for values. AECharts normalizes the values automatically. They don't need to add up to exactly 100.

What export formats are available?

Every chart exports ready to use in PowerPoint or Google Slides, or as an image for reports.

How many categories should a half donut chart have?

Two to three categories is ideal, the arc reads cleanly and there's still room for a label in the center. At four or more, the narrow segments at the arc ends become hard to distinguish. For many categories, use a full donut, pie chart, or horizontal bar chart instead.

What is the difference between a half donut chart and a gauge chart?

A gauge chart typically shows a single value on a scale (like a speedometer), it has a needle or single filled arc indicating progress. A half donut chart shows proportional segments across the arc, making it suited for part-to-whole data rather than a single metric on a range.

Is there a free plan?

Yes. AECharts is free to start, exports on the free plan include a watermark. The paid plan removes it, starting at $12/month billed annually. No credit card required to start.

Can I use a half donut chart in a presentation?

Yes. Charts export ready to drop directly into PowerPoint and Google Slides. The flat-baseline arc format works especially well in two-column slides and dashboard-style decks, the compact shape leaves room for supporting text alongside it.

When to Use a Half Donut Chart

Half donut charts work best when you have 2–3 proportional categories and one key metric worth anchoring in the center of the arc.

Goal & Quota Attainment: Sales at 84% of target. A filled arc sweeping to 84° with the percentage in the center is more immediate than a progress bar, and more polished than a number in text.
Dashboard KPI Card: A single metric, NPS, retention rate, utilization, as a half arc with the value centered below. Fits cleanly in a card-style dashboard panel without competing with surrounding content.
Portfolio Allocation: Two or three asset classes across the arc, equities, bonds, alternatives, with total AUM in the center. The flat baseline makes it natural in a two-column fund report.
Budget Split: Marketing, headcount, and infrastructure across the arc, with total spend in the center. Compact enough to sit alongside a data table in a quarterly review deck.
Survey Sentiment: Positive, neutral, and negative response rates as three arc segments. The center shows total respondents or the headline agree percentage at a glance.
Market Share: Your share vs competitors across the semicircle, your percentage in the center. The arc format reads like a speedometer, making the dominant position feel authoritative.

Half Donut vs Full Donut vs Gauge Chart

Three ring-style charts, each suited to a different kind of data.

Half Donut Chart

Best for: 2–3 proportional categories with a center metric, in a compact horizontal format.
Strength: Flat baseline anchors visually in dashboards and two-column layouts. Center space below the arc is natural for a headline number.
Use when: KPI cards, goal completion, portfolio splits, or dashboard panels.

Full Donut Chart

Best for: 2–5 categories with a center metric, where the full-circle format is preferred.
Strength: More segment capacity than a half donut, up to 5 readable slices. Center accommodates larger text.
Use when: Revenue by segment, budget allocation, or any 3–5 category split where total context matters.

Gauge Chart

Best for: A single value on a defined scale, progress toward a target or a score out of 100.
Strength: Needle or filled arc makes the position on a scale immediately readable. No categories needed.
Use when: NPS score, completion rate, satisfaction index, one number on a defined range.

AECharts supports all three. Switch between half donut, full donut, and gauge to match your data and layout.
