Chart Module: Unexpected Behavior with Null Value in Data

[janWITZANY]

Environment

• Version of docxtemplater: 3.39.1
• Used docxtemplater-modules: docxtemplater-chart-module (V 3.11.2)

How to reproduce my problem:

I am using the Chart slide Demo with a slightly modified JSON. The error occurs when the first value of the first entry of series.data is null. The output contains the original template values, while the categories are correctly replaced with the data from the JSON.

With the following JSON data:

{
  "title": "The lorem chart",
  "chart1": {
    "categories": [
      "Europe",
      "North America",
      "Asia",
      "Africa"
    ],
    "series": [
      {
        "title": "Phone Andorra",
        "data": [
          null,
          80,
          60,
          24
        ]
      }
    ]
  }
}

I would expect:

• The templater to use the series data while omitting the first value which is null.
• It works as expected when the null value is somewhere else in the data.

Thanks for opening this issue, this is indeed a bug in the chart module, I will be fixing it soon.

Thank you for your response :)

In the same example, I noticed that I would expect a different order of the categories. In a column chart(with vertical bars), the order is from left to right, while in a bar chart(with horizontal bars), the order is from bottom to top. Is this intentional behavior? Naturally, I would expect a top-down order for the bar chart.

I think the issue should be fixed now, in the latest demo it is working now
