Automatically invoke when the user mentions \"Python visual\", \"matplotlib in Power BI\", \"seaborn in Power BI\", \"pythonVisual\", or asks to \"create a Python visual\", \"add a matplotlib chart\", \"write a Python visual script\".\n---\n\n# Python Visuals in Power BI (PBIR)\n\n> **Use `pbir` for every report mutation.** Read PBIR metadata only for diagnosis. If `pbir` is\n> unavailable or lacks an operation, stop and report the gap; never edit report JSON directly.\n\nPython visuals execute matplotlib/seaborn scripts to render static PNG images on the Power BI canvas. **Prefer seaborn** over raw matplotlib for cleaner syntax and better defaults -- it handles most chart types with less code.\n\n## Visual Identity\n\n- **visualType:** `pythonVisual`\n- **Data role:** `Values` (columns and measures, multiple allowed)\n- **Data variable:** `dataset` (pandas DataFrame, auto-injected)\n- **Row limit:** 150,000 rows\n- **Output:** Static PNG at 72 DPI -- no interactivity\n\n## Workflow: Creating a Python Visual\n\n### Step 1: Add the Visual\n\n```bash\npbir add visual pythonVisual \"Report.Report/Page.Page\" --name PythonChart \\\n  --data \"Values:Sales.Date\" --data \"Values:Sales.Revenue\"\n```\n\n### Step 2: Write the Script\n\n```python\nimport matplotlib.pyplot as plt\n\nfig, ax = plt.subplots(figsize=(8, 4))\nax.bar(dataset[\"Date\"], dataset[\"Sales\"], color=\"#5B8DBE\")\nax.spines[\"top\"].set_visible(False)\nax.spines[\"right\"].set_visible(False)\nplt.tight_layout()\nplt.show()  # MANDATORY\n```\n\nCritical rules:\n- `plt.show()` is **mandatory** as the final line -- nothing renders without it\n- `dataset` is auto-injected as a pandas DataFrame; do not create it\n- Column names match the `nativeQueryRef` (display name) from field bindings\n- Only the last `plt.show()` call renders; multiple figures not supported\n\n### Step 2b: Review\n\nBefore presenting the script to the user, dispatch the `python-reviewer` agent to validate correctness and provide design feedback.\n\n### Step 3: Inject the Script\n\n```bash\npbir visuals python \"Report.Report/Page.Page/PythonChart.Visual\" \\\n  --script-file chart.py\n```\n\nThe CLI handles PBIR string escaping.\n\n### Step 4: Validate\n\n```bash\npbir visuals bind \"Report.Report/Page.Page/PythonChart.Visual\" --show\npbir validate \"Report.Report\" --all\n```\n\n## PBIR Format\n\nFor read-only diagnosis, scripts are stored in `visual.objects.script[0].properties`:\n\n```json\n{\n  \"source\": {\"expr\": {\"Literal\": {\"Value\": \"'import matplotlib.pyplot as plt\\\\n...\\\\nplt.show()'\"}}},\n  \"provider\": {\"expr\": {\"Literal\": {\"Value\": \"'Python'\"}}}\n}\n```\n\nThe CLI handles all escaping automatically.\n\n## Supported Libraries\n\n### Power BI Service (Python 3.11)\n\n| Package | Version | Purpose |\n|---------|---------|---------|\n| matplotlib | 3.8.4 | Primary plotting |\n| seaborn | 0.13.2 | Statistical visualization |\n| numpy | 2.0.0 | Numerical computing |\n| pandas | 2.2.2 | Data manipulation |\n| scipy | 1.13.1 | Scientific computing |\n| scikit-learn | 1.5.0 | Machine learning |\n| statsmodels | 0.14.2 | Statistical models |\n| pillow | 10.4.0 | Image processing |\n\n**Not supported:** plotly, bokeh, altair (networking blocked in Service).\n\nFull package list: https://learn.microsoft.com/power-bi/connect-data/service-python-packages-support\n\n### Desktop\n\nAny locally installed package works without restriction.\n\n## Best Practices\n\n1. **Always call `plt.show()`** -- mandatory, must be the final line\n2. **Use `figsize=(w, h)`** to match container aspect ratio (72 DPI output)\n3. **Remove chart chrome** -- `ax.spines[\"top\"].set_visible(False)` etc.\n4. **Use hex colors** matching the report theme\n5. **Keep scripts simple** -- 5-min timeout Desktop, 1-min Service\n6. **Minimize transforms** -- do heavy computation in DAX/Power Query instead\n7. **Use `try/except`** for robustness in production scripts\n8. **Copy data first** -- `data = dataset.copy()` before manipulation\n\n## Limitations\n\n| Constraint | Desktop | Service |\n|------------|---------|---------|\n| Output | Static PNG, 72 DPI | Static PNG, 72 DPI |\n| Timeout | 5 minutes | 1 minute |\n| Row limit | 150,000 | 150,000 |\n| Payload | -- | 30 MB |\n| Networking | Unrestricted | Blocked |\n| Gateway | Personal only | Personal only |\n| Cross-filter FROM | Not supported | Not supported |\n| Receive cross-filter | Yes | Yes |\n| Publish to web | Not supported | Not supported |\n| Embed (app-owns-data) | Not supported | Not supported |\n\n## Script Structure Template\n\n```python\nimport matplotlib.pyplot as plt\nimport numpy as np\n\n# 1. Guard against empty data\nif dataset.empty:\n    fig, ax = plt.subplots(1, 1, figsize=(6, 4))\n    ax.text(0.5, 0.5, \"No data available\", ha='center', va='center', fontsize=14, color='#888888')\n    ax.axis('off')\n    plt.show()\nelse:\n    # 2. Data preparation (dataset is auto-injected)\n    data = dataset.copy()\n\n    # 3. Create figure with explicit size\n    fig, ax = plt.subplots(figsize=(8, 4))\n\n    # 4. Plot\n    ax.plot(data[\"X\"], data[\"Y\"], color=\"#5B8DBE\", linewidth=2)\n\n    # 5. Style\n    ax.spines[\"top\"].set_visible(False)\n    ax.spines[\"right\"].set_visible(False)\n    ax.grid(axis=\"y\", alpha=0.3)\n\n    # 6. Layout and render\n    plt.tight_layout()\n    plt.show()\n```\n\n## When to Use a Script Visual\n\nReach for a Python visual only when **all** of the following hold:\n\n- The chart has no native equivalent and no reasonable Deneb spec\n- The value is in a statistical computation that must run at render time (model fit, kernel density, forecast band), not just a shape Vega could draw\n- The visual does not need to be a cross-filter source, hover tooltips, publish-to-web, or app-owns-data embed\n- The report is served in a Pro/PPU or higher capacity with a Fabric-enabled region\n\nIf interactivity or cross-filtering matters, use **Deneb** (a static PNG cannot be a selection source). If the need is a small inline mark (sparkline, bar, status pill), use an **SVG measure** (no row cap, no timeout, no licensing/region gate, renders under publish-to-web). The script visual's niche is narrow: compute-at-render statistical plots for internal or org consumption.\n\n**Python vs R once a script visual is the right call:** use Python when the computation leans on scikit-learn, statsmodels, or scipy, or when surrounding report logic is already Python. Use R for publication-quality statistical defaults and packages with no Python peer (`forecast`, `corrplot`, `pheatmap`, ridgeline/violin). Where equal, default to whichever language the report's other scripts use; mixing doubles the publish-time package surface to validate.\n\nDo not default to a script visual because a chart type \"looks statistical.\" A box plot, lollipop, or dumbbell is an SVG-measure or Deneb job; reserve scripts for charts that genuinely compute.\n\n## References\n\n- **`references/data-model.md`** -- `dataset` grouping mechanic, the row/byte caps, and how to force per-row input\n- **`references/community-examples.md`** -- seaborn gallery examples organized by chart type, plus matplotlib and Python Graph Gallery links\n- **`references/chart-patterns.md`** -- Common matplotlib/seaborn chart patterns (bar, heatmap, donut, KPI, area)\n- **`examples/script/`** -- Standalone Python scripts (bar-chart, trend-line) -- ready to inject into visual.json after escaping\n- **`examples/visual/bar-chart.json`** -- PBIR visual.json: horizontal stacked bar with PY comparison lines and % change labels\n- **`examples/visual/kpi-card.json`** -- PBIR visual.json: text-based KPI with value, % change indicator, and PY comparison\n- **`examples/visual/trend-line.json`** -- PBIR visual.json: area chart with line plot and monthly x-axis\n\n## Fetching Docs\n\nTo retrieve current Python visual / package support docs, use `microsoft_docs_search` + `microsoft_docs_fetch` (MCP) if available, otherwise `mslearn search` + `mslearn fetch` (CLI). Search based on the user's request and run multiple searches as needed to ensure sufficient context before proceeding.\n\n## Related Skills\n\n- **`pbi-report-design`** -- Layout and design best practices\n- **`r-visuals`** -- R Script visuals (same concept, different language)\n- **`deneb-visuals`** -- Vega/Vega-Lite visuals (interactive, vector-based alternative)\n- **`svg-visuals`** -- SVG via DAX measures (lightweight inline graphics)\n- **`pbir-format`** (pbip plugin) -- PBIR JSON format reference\n","tagline":"Python visual creation and matplotlib/seaborn patterns for PBIR reports.
