# Matrix Chart Generator Generate correlation and comparison matrix charts with color intensity mapping and grid layout > Canonical page: https://elysiatools.com/en/tools/matrix-chart-generator - **Category:** Data Visualization - **Keywords:** matrix, correlation, heatmap, comparison, grid, intensity, color mapping ## Overview The Matrix Chart Generator allows you to transform raw numerical data into clear, visual correlation or comparison matrices. By mapping values to color intensities, this tool helps you quickly identify patterns, trends, and relationships within your datasets using a customizable grid layout. ## Inputs - **Matrix Data** (textarea): Matrix data as 2D array. Supports JSON array or CSV format with comma-separated values - **Chart Title** (text): Title that will be displayed above the matrix chart - **Color Scheme** (select): Select color scheme - **Background Color** (color): Background color for the chart - **Cell Size** (number): Size of each cell in pixels - **Font Size** (number): Font size for cell values - **Minimum Value** (number): Minimum value for color scale (leave empty for auto) - **Maximum Value** (number): Maximum value for color scale (leave empty for auto) - **Chart Width** (number): Width of the chart in pixels - **Chart Height** (number): Height of the chart in pixels - **Show Cell Values** (checkbox): Display numeric values inside cells - **Show Row/Column Labels** (checkbox): Display row and column labels (if available) - **Show Grid Lines** (checkbox): Display grid lines between cells - **Round Values** (checkbox): Round values to whole numbers for display ## When to use - Visualizing correlation coefficients between multiple variables in a dataset. - Creating heatmaps to compare performance metrics across different categories. - Presenting complex numerical relationships in a simplified, color-coded grid format. ## How it works - Input your data as a 2D JSON array or a comma-separated CSV string. - Select a color scheme to represent the intensity of your data values. - Adjust display settings like cell size, font size, and grid visibility to suit your layout needs. - Generate the chart to visualize your data with automatic or custom value scaling. ## Use cases - Analyzing statistical correlations between financial indicators. - Comparing team performance metrics across different project quarters. - Visualizing survey response intensity across various demographic segments. ## Frequently asked questions ### What data formats are supported? You can input data as a 2D JSON array or a CSV string with comma-separated values. ### Can I set custom ranges for the color scale? Yes, you can specify custom Minimum and Maximum values to define the color intensity range, or leave them blank for automatic scaling. ### Is it possible to hide the numeric values inside the cells? Yes, simply uncheck the 'Show Cell Values' option in the settings. ### Can I change the size of the matrix cells? Yes, you can adjust the 'Cell Size' setting between 20 and 100 pixels to fit your requirements. ### Does the tool support different color palettes? Yes, you can choose from several presets including Blue, Red, Green, Purple, Orange, Teal, Grayscale, and Rainbow scales. ## Related tools - [Heatmap Generator](https://elysiatools.com/en/tools/heatmap-generator): Generate customizable heatmaps from data, perfect for visualizing data density, correlations, and patterns - [Fitness Workout PDF Generator](https://elysiatools.com/en/tools/fitness-workout-pdf-generator): Generate a printable workout-plan PDF from JSON or CSV data with exercise tables, progress boxes, and optional QR video links - [Markdown Table Generator](https://elysiatools.com/en/tools/markdown-table-generator): Generate formatted Markdown tables from CSV, JSON, or array data with alignment, header styles, width control, and merge hints - [Pivot Table Generator](https://elysiatools.com/en/tools/pivot-table-generator): Generate interactive pivot tables from CSV/JSON data with customizable row, column, and value field configurations - [CSV to Database Migration Planner](https://elysiatools.com/en/tools/csv-to-database-migration-planner): Infer a relational schema from CSV data and generate create-table plus ALTER migration plans for PostgreSQL, MySQL, SQLite, or SQL Server - [Test Data Faker Builder](https://elysiatools.com/en/tools/test-data-faker-builder): Generate structured test data from field configuration with support for faker fields, regex rules, credit cards, IDs, and batch export - [JSON-LD Generator from CSV](https://elysiatools.com/en/tools/json-ld-generator-from-csv): Turn CSV or Excel rows into Schema.org JSON-LD for articles, products, or events, with validation-ready output for SEO workflows - [Bar Chart Generator](https://elysiatools.com/en/tools/bar-chart-generator): Generate customizable bar charts from data with various styling options ## Samples - [CSV Samples](https://elysiatools.com/en/samples/csv-samples): Sample CSV files with various data types, sizes, and complexity levels - [Python Samples](https://elysiatools.com/en/samples/python): Essential Python code examples and Hello World demonstrations - [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 - [QR Code Samples](https://elysiatools.com/en/samples/qrcode-samples): Sample QR code images for testing QR code reading and generation tools
