Ensure the number of labels matches the number of data points.\n* **Use Real Data Sources:** Replace the `Edit Fields: Set JSON data to test` node with nodes that fetch data from real sources like:\n * HTTP Request (APIs)\n * Postgres \/ MongoDB nodes (Databases)\n * Google Sheets node\n * Ensure the output data from your source node is formatted similarly (providing `labels` and `salesData` arrays). You might need another Set node to structure the data correctly before the QuickChart node.\n* **Change Chart Type:** In the QuickChart node, modify the `Chart Type` parameter (e.g., change from `line` to `bar`, `pie`, `doughnut`, etc.).\n* **Customize Chart Appearance:** Explore the `Chart Options` parameter within the QuickChart node to add titles, change colors, modify axes, etc., using QuickChart's standard JSON configuration options.\n* **Use Datasets (Recommended for Complex Charts):** For multiple lines\/bars or more control, configure datasets explicitly in the QuickChart node:\n * Remove the expression from the top-level `Data` field.\n * Go to `Dataset Options` -> `Add option` -> `Add dataset`.\n * Set the `Data` field within the dataset using an expression like `{{ $json.jsonData.salesData }}`.\n * You can add multiple datasets this way.\n* **Change Output Destination:** Replace the `Google Drive: Upload File` node with other nodes to handle the chart image differently:\n * `Write Binary File`: Save the chart to the local filesystem where n8n is running.\n * `Slack` \/ `Discord` \/ `Telegram`: Send the chart to messaging platforms.\n * `Move Binary Data`: Convert the image to Base64 to embed in HTML or return via webhook response."
