Supports JSON object or text format with categories and multiple data series - **Chart Title** (text): Title that will be displayed above the chart - **Series Colors** (text): Colors for multiple series (comma-separated hex colors). Leave empty for default colors. - **Fill Opacity** (number): Opacity of the radar area fill (0.0 to 1.0) - **Line Width** (number): Width of the radar area border lines in pixels - **Chart Size** (number): Size of the square chart in pixels - **Start Angle** (number): Starting angle in degrees (0 = top, 90 = right) - **Polygon Sides** (number): Number of sides for the radar polygon (3-12, leave empty for auto based on categories) - **Maximum Value** (number): Maximum value for the radar scale (leave empty for auto-scale) - **Minimum Value** (number): Minimum value for the radar scale - **Background Color** (color): Background color for the chart container - **Grid Color** (color): Color for the grid lines and circles - **Show Grid** (checkbox): Display grid circles and radial lines - **Show Data Points** (checkbox): Display data points on the radar vertices - **Show Values on Points** (checkbox): Display the actual values on data points - **Show Legend** (checkbox): Display a legend below the chart ## When to use - Comparing performance metrics across multiple categories for different entities. - Visualizing skill sets, product features, or survey results in a polar coordinate system. - Creating clear, comparative summaries for reports or presentations. ## How it works - Input your data in JSON format or as a comma-separated list of categories and series values. - Customize the visual appearance by adjusting settings like chart title, colors, line width, and fill opacity. - Toggle display options such as grid lines, data points, and legends to suit your specific presentation needs. - Generate and download your custom radar chart for use in documents or web projects. ## Use cases - Skill assessment visualization for team members or job candidates. - Product feature comparison against competitors in a market analysis. - Tracking progress across different KPIs in a balanced scorecard. ## Frequently asked questions ### What data formats are supported? You can provide data as a JSON object containing categories and series, or as simple text with comma-separated values. ### Can I compare multiple items at once? Yes, the tool supports multiple data series, allowing you to overlay different datasets on the same radar chart. ### Is it possible to customize the chart colors? Yes, you can specify custom hex colors for each series in the 'Series Colors' field. ### How do I change the scale of the chart? You can manually set the 'Maximum Value' and 'Minimum Value' fields to define the scale, or leave them blank for auto-scaling. ### Can I hide the grid or legend? Yes, the tool provides checkboxes to toggle the visibility of the grid, data points, values, and the legend. ## Related tools - [Waterfall Chart Generator](https://elysiatools.com/en/tools/waterfall-chart-generator): Create waterfall charts to visualize cumulative changes with positive/negative value distinction and subtotal display - [Donut Chart Generator](https://elysiatools.com/en/tools/donut-chart-generator): Generate customizable donut charts (ring charts) from data with various styling options, perfect for showing proportions with a central space - [Funnel Chart Generator](https://elysiatools.com/en/tools/funnel-chart-generator): Generate customizable funnel charts from data, perfect for showing conversion rates, sales pipelines, and process flows - [Pictograph Generator](https://elysiatools.com/en/tools/pictograph-generator): Create pictographs using icons/symbols to represent quantities with customizable icons, colors, and layouts - [Progress Bar Generator](https://elysiatools.com/en/tools/progress-bar-generator): Generate customizable progress bars from data, perfect for showing completion status, rankings, or comparative values - [Range Chart Generator](https://elysiatools.com/en/tools/range-chart-generator): Create range charts to visualize min-max value ranges with median markers and outlier detection - [Rose Chart Generator](https://elysiatools.com/en/tools/rose-chart): Generate beautiful Nightingale rose charts (coxcomb charts) to visualize data through both angle and area, perfect for comparative analysis and historical data presentation - [Spider Chart Generator](https://elysiatools.com/en/tools/spider-chart-generator): Generate simplified spider (radar) charts for multi-dimensional data comparison and analysis ## Samples - [ELK Stack Log Analysis Samples](https://elysiatools.com/en/samples/elk-stack-samples): Comprehensive ELK Stack (Elasticsearch, Logstash, Kibana) samples for log aggregation, processing, and visualization in distributed systems - [QR Code Samples](https://elysiatools.com/en/samples/qrcode-samples): Sample QR code images for testing QR code reading and generation tools - [Grafana Advanced Application Samples](https://elysiatools.com/en/samples/grafana-samples): Comprehensive Grafana samples covering advanced dashboard design, alerting configurations, data source integrations, and plugin development - [Distributed Tracing Samples](https://elysiatools.com/en/samples/distributed-tracing-samples): Comprehensive distributed tracing examples using Jaeger, OpenTelemetry, and other modern observability tools for microservices architecture ## Related content - [Chart and Diagram Generators](https://elysiatools.com/en/hubs/chart-diagram-generators): Generate bar, line, pie, donut, scatter, radar, Gantt, Sankey, heatmap, funnel, treemap, and dozens more charts and diagrams from your own data in one visualization hub. - [JSON Interchange and Format Translation Tools](https://elysiatools.com/en/hubs/json-convert): Compare JSON conversion tools for CSV, YAML, TOML, GraphQL, XML, Markdown, Excel, BSON, EDN, and related structured formats in one hub. - [Text Case, Encoding, and Normalization Conversion Tools](https://elysiatools.com/en/hubs/text-convert): Compare text case conversion, character-width conversion, encoding conversion, quoted-printable handling, and inline text normalization tools in one hub. - [JSON Inspection, Diff, and Transformation Tools](https://elysiatools.com/en/hubs/json-utility): Compare JSON formatting, diffing, path inspection, schema validation, merging, transformation, and export tools in one hub for API and data workflows.
