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."
