Supports 9 chart types (bar, line, pie, doughnut, scatter, bubble, radar, polar area, horizontal bar), 5 preset themes plus custom styling, and 4 export formats (PNG, SVG, PDF, WebP). Charts can be returned as cloud-stored file URLs or base64-encoded data for immediate embedding. Powered by QuickChart API (Chart.js compatible). --- ## Actions ### generate_chart Generate a chart image from structured data with theme and format options. **Required Parameters:** - `chart_type` (string): Type of chart. One of: `"bar"`, `"line"`, `"pie"`, `"doughnut"`, `"scatter"`, `"bubble"`, `"radar"`, `"polarArea"`, `"horizontalBar"` - `data` (object): Chart.js compatible data object.

One of: `"png"` (raster), `"svg"` (vector, scalable), `"pdf"` (document), `"webp"` (compressed). - `device_pixel_ratio` (integer, default: 1): `1` for normal displays, `2` for retina/high-DPI displays. - `custom_options` (object): Custom Chart.js options object to override theme defaults. Supports any Chart.js 3.x/4.x option (plugins, scales, etc.). - `return_base64` (boolean, default: false): If true, returns base64-encoded image data instead of a file URL. Useful for embedding in emails or immediate display. - `store_file` (boolean, default: true): If true, stores the chart in cloud storage and returns a signed download URL. - `expiration_days` (integer, default: 7, range: 1-7): Number of days until the stored file expires and is automatically deleted. **Example - Simple Bar Chart:** ```json { "action": "generate_chart", "chart_type": "bar", "data": { "labels": ["Q1", "Q2", "Q3", "Q4"], "datasets": [{"label": "Revenue", "data": [45000, 52000, 48000, 61000]}] }, "title": "Quarterly Revenue 2025", "theme": "corporate", "width": 800, "height": 500 } ``` **Example - Multi-Dataset Line Chart (Dark Theme, Retina):** ```json { "action": "generate_chart", "chart_type": "line", "data": { "labels": ["Jan", "Feb", "Mar", "Apr", "May", "Jun"], "datasets": [ {"label": "Product A", "data": [12, 19, 15, 22, 28, 25]}, {"label": "Product B", "data": [8, 14, 18, 16, 20, 24]} ] }, "title": "Product Sales Comparison", "theme": "modern_dark", "width": 1000, "height": 600, "output_format": "png", "device_pixel_ratio": 2 } ``` **Example - Pie Chart (Colorful):** ```json { "action": "generate_chart", "chart_type": "pie", "data": { "labels": ["Desktop", "Mobile", "Tablet"], "datasets": [{"data": [55, 35, 10]}] }, "title": "Traffic by Device", "theme": "colorful" } ``` **Example - Scatter Plot (Academic, SVG):** ```json { "action": "generate_chart", "chart_type": "scatter", "data": { "datasets": [{ "label": "Sample Data", "data": [{"x": 10, "y": 20}, {"x": 15, "y": 25}, {"x": 20, "y": 22}, {"x": 25, "y": 30}] }] }, "title": "Correlation Analysis", "theme": "academic", "width": 700, "height": 500, "output_format": "svg" } ``` **Example - Custom Styled Chart:** ```json { "action": "generate_chart", "chart_type": "bar", "data": { "labels": ["Mon", "Tue", "Wed", "Thu", "Fri"], "datasets": [{"label": "Tasks Completed", "data": [5, 8, 12, 7, 10]}] }, "title": "Weekly Productivity", "theme": "custom", "background_color": "#F5F5F5", "custom_options": { "plugins": {"legend": {"display": false}}, "scales": {"y": {"beginAtZero": true, "grid": {"color": "rgba(0, 0, 0, 0.1)"}}} } } ``` **Example - Base64 Return (No File Storage):** ```json { "action": "generate_chart", "chart_type": "line", "data": { "labels": ["1", "2", "3", "4", "5"], "datasets": [{"label": "Values", "data": [10, 20, 15, 25, 30]}] }, "theme": "minimal", "return_base64": true, "store_file": false } ``` **Example - PDF Export with Custom Expiration:** ```json { "action": "generate_chart", "chart_type": "bar", "data": { "labels": ["Category A", "Category B", "Category C"], "datasets": [{"label": "Results", "data": [65, 85, 75]}] }, "title": "Survey Results", "theme": "corporate", "output_format": "pdf", "width": 800, "height": 600, "expiration_days": 3 } ``` **Response fields:** - `chart_type`: Chart type used - `theme`: Theme applied - `format`: Output format - `width`, `height`: Dimensions - `size_bytes`: File size in bytes - When `return_base64` is true: `base64_data` (string), `content_type` (MIME type) - When `store_file` is true: `file_id` (string), `signed_url` (temporary download URL), `expiration_date` (ISO date) --- ## Data Format Standard chart types (bar, line, pie, doughnut, radar, polarArea, horizontalBar): ```json { "labels": ["Label 1", "Label 2", "Label 3"], "datasets": [{ "label": "Dataset Name", "data": [10, 20, 30], "backgroundColor": "optional color override", "borderColor": "optional border color", "borderWidth": 1 }] } ``` Scatter and bubble charts use point objects instead of simple values: ```json { "datasets": [{ "label": "Points", "data": [{"x": 10, "y": 20}, {"x": 15, "y": 25}] }] } ``` Multiple datasets are supported. Theme colors are auto-assigned to datasets that do not specify their own colors. --- ## Workflows 1. **Business Dashboard Chart** - Use `generate_chart` with `theme: "corporate"`, a bar or line chart, and `store_file: true` to get a signed URL for embedding in reports. 2. **Email-Embedded Chart** - Use `generate_chart` with `return_base64: true` and `store_file: false` to get base64 data for inline embedding in emails. 3. **Scientific Publication Figure** - Use `generate_chart` with `theme: "academic"`, `output_format: "svg"` for scalable vector output suitable for print. 4. **Marketing Infographic** - Use `generate_chart` with `theme: "colorful"`, pie or doughnut chart, and `device_pixel_ratio: 2` for high-resolution social media images. 5. **Dark Mode Presentation Slide** - Use `generate_chart` with `theme: "modern_dark"`, large dimensions (1920x1080), and `device_pixel_ratio: 2`. 6. **Custom Branded Chart** - Use `theme: "custom"` with `custom_options` to apply your own colors, fonts, grid styles, and legend placement. --- ## Notes - Maximum chart dimensions are 2000x2000 pixels. - Stored files expire after 1-7 days (configurable via `expiration_days`). - The `data` object must contain at least a `datasets` array. The `labels` array is required for most chart types but not for scatter/bubble charts. - When using `theme: "custom"`, no preset styling is applied. Combine with `custom_options` for full control. - `custom_options` merges on top of theme defaults, so you can start with a theme and override specific options. - The `device_pixel_ratio: 2` option doubles the rendered resolution (useful for retina displays) but also increases file size. - If both `return_base64: true` and `store_file: true` are set, you get both the base64 data and a stored file URL. - Validation: `chart_type` and `data` are required for `generate_chart`. Missing either returns a 400 error. - Recommended sizes: social media 800x600, reports 1000x600, presentations 1920x1080. ### Frequently Asked Questions #### How do I connect this tool to an external agent? - Page URL: https://www.agentpmt.com/faq - Markdown URL: https://www.agentpmt.com/faq?format=agent-md You can install the local MCP server by opening a terminal and running: ``` npm install -g @agentpmt/mcp-router agentpmt-setup ``` This will connect you to local agents like Claude Code, Windsurf, Grok Build, Cursor, etc. Alternatively you can connect to the hosted version with this config block, no installation required: ``` { "mcpServers": { "agentpmt": { "type": "streamable-http", "url": "https://api.agentpmt.com/mcp", "headers": { "Authorization": "Bearer ", "x-instance-metadata": "{\"client\":\"generic-mcp\",\"platform\":\"remote\"}" } } } } ``` [View MCP Connection Instructions](/docs/mcp-reference/connection) for more details. #### How does an external agent use this tool? - Page URL: https://www.agentpmt.com/faq - Markdown URL: https://www.agentpmt.com/faq?format=agent-md After the external agent is connected to an Agent Group that can use this tool, paste this prompt into the agent: > Use the AgentPMT-Tool-Search-and-Execution tool. First call action 'get\_instructions' so you know how to use the tool search interface. Then call action 'get\_schema' with tool\_id 69836138abdf9c195542120a ("Chart Generator"). After reading the schema and any returned instructions, tell me what this tool can do, we are going to be using it The agent should fetch the tool schema first, collect the required parameters for your request, and then call the tool through AgentPMT. ### Dependencies This product has no public dependency products.
