# Histogram Maker Bin numeric data into intervals and draw a histogram to visualize a statistical distribution > Canonical page: https://elysiatools.com/en/tools/histogram-maker - **Category:** Data Visualization - **Keywords:** histogram, statistics, distribution, binning, frequency, normal curve ## Overview Parses a list of numbers, selects a bin count via Sturges / Freedman-Diaconis / Scott rules or a fixed count, counts the values per bin, and renders a bar-style SVG histogram with optional normal-curve overlay and a summary of descriptive statistics (mean, median, standard deviation, quartiles). ## Inputs - **Data Values** (textarea): A list of numeric values to bin and plot - **Binning Method** (select) - **Number of Bins** (number): Used only when method is "Fixed Count" - **Show Normal Curve** (checkbox) - **Show Statistics** (checkbox) - **Color Scheme** (select) ## When to use - When you need to analyze the frequency distribution of a raw dataset without writing code. - When comparing your empirical data distribution against a theoretical normal curve. - When you want to quickly calculate descriptive statistics alongside a visual chart for reports. ## How it works - Input your numeric values separated by commas, spaces, or newlines into the data field. - Select your preferred binning method, such as Auto, Sturges, Freedman-Diaconis, or a fixed bin count. - Configure visual options including the color scheme, normal curve overlay, and descriptive statistics display. - Generate the interactive SVG histogram and review the calculated statistical summary. ## Use cases - Analyzing student exam scores to evaluate grade distribution and class performance. - Visualizing manufacturing part dimensions to check for variance and quality control. - Examining website response times to identify latency patterns and outliers. ## Frequently asked questions ### What binning methods are supported? The tool supports Auto, Sturges, Freedman-Diaconis (FD), Scott, and Fixed Count methods. ### How should I format my input data? Enter your numbers separated by commas, spaces, or newlines directly into the text area. ### Can I overlay a normal distribution curve? Yes, you can toggle the 'Show Normal Curve' option to overlay a theoretical normal curve on your histogram. ### What descriptive statistics are calculated? The tool calculates and displays the mean, median, standard deviation, and quartiles of your dataset. ### Can I customize the colors of the histogram? Yes, you can choose from Default, Warm, Cool, and Pastel color schemes. ## Related tools - [Venn Diagram Generator](https://elysiatools.com/en/tools/euler-diagram-generator): Generate customizable Venn diagrams to visualize set relationships, intersections, exclusions, and hierarchical structures - [Calendar Heatmap Generator](https://elysiatools.com/en/tools/calendar-heatmap): Generate GitHub-style calendar heatmaps to visualize activity patterns over time, perfect for tracking yearly contributions, habits, or metrics - [Org Chart Maker](https://elysiatools.com/en/tools/org-chart-maker): Render hierarchical JSON into a vertical organizational chart with names and titles - [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 - [Sankey Diagram Generator](https://elysiatools.com/en/tools/sankey-diagram-generator): Generate Sankey diagrams to visualize flow distributions and energy transfers between different nodes - [Venn Diagram Maker](https://elysiatools.com/en/tools/venn-diagram-maker): Draw a Venn diagram for 2 to 4 sets, labeling each region with its size and intersections - [Flowchart Maker](https://elysiatools.com/en/tools/flowchart-maker): Describe nodes and connections in Mermaid-style syntax and generate a layered flowchart diagram - [Mind Map Maker](https://elysiatools.com/en/tools/mindmap-maker): Turn an indented list into a mind map with hierarchical branches ## Samples - [Web Image Processing Python Samples](https://elysiatools.com/en/samples/web-image-processing-python): Web Python image processing examples using PIL/Pillow including reading, saving, resizing, and format conversion - [Android Image Processing Java Samples](https://elysiatools.com/en/samples/android-image-processing-java): Android Java image processing examples including reading/saving images, scaling, and format conversion - [Android Image Processing Kotlin Samples](https://elysiatools.com/en/samples/android-image-processing-kotlin): Android Kotlin image processing examples including reading/saving images, scaling, and format conversion - [Web Image Processing Rust Samples](https://elysiatools.com/en/samples/web-image-processing-rust): Web Rust image processing examples including image read/save, scaling, and format conversion ## 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. - [Audio Encoding and Format Conversion Tools](https://elysiatools.com/en/hubs/audio-convert): Compare audio format conversion, bitrate changes, sample-rate conversion, codec swaps, and export tools in one hub for delivery and archive workflows. - [Image Format Conversion and Animated Export Tools](https://elysiatools.com/en/hubs/image-convert): Compare image format converters for JPG, PNG, GIF, AVIF, WebP, TIFF, ICO, base64, and animation-friendly exports in one 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.
