How do I format the JSON input for QuickChart to display multiple data series in a bar chart?

I'm trying to configure the QuickChart node in n8n to generate a bar chart where each x-axis label displays two bars (representing two data series).

With the current pinned input and node settings, the chart displays the labels along the x-axis but no bars appear. I'm unsure what structure the value of the Data property should have.

Below is the intended JSON structure for a bar chart with two data series that QuickChart expects:

JSONCopied
{
  "labels": ["Label 1", "Label 2", "Label 3"],
  "datasets": [
    {
      "label": "Series 1",
      "data": [10, 20, 30]
    },
    {
      "label": "Series 2",
      "data": [15, 25, 35]
    }
  ]
}

This JSON includes:

• A "labels" array that sets the x-axis labels
• A "datasets" array with objects for each series, each having a "label" for the series name and a "data" array for numeric values corresponding to each label

Please confirm that:

1. The JSON is valid and exactly matches the expected structure.
2. The pinned input data in your workflow is formatted as shown.
3. The QuickChart node is configured to work with a JSON object containing the keys "labels" and "datasets" as required by QuickChart’s API.

If there are further issues, double-check that the output from the previous node precisely matches this structure before feeding it into the QuickChart node.
