Chart Tag Limitations

info

This article documents some limitations to Windward support of Microsoft Office charts. For more details about Windward support for Microsoft Office charts, see Support for Microsoft Office Charts.
To understand these limitations, it is important to distinguish between the different types of charts.

The Three Types of Charts​

Microsoft Office Chart Tags​

Office Chart Tags are Tags that look and behave like Microsoft Office charts. The output of an Office Chart Tag is an Office chart for DOCX, and a bitmap image for other output formats.

Classic Chart Tags​

The Chart Tag has existed since long before there was support for Office Chart Tags and Native Charts, and it is still an option. It is the only option in Excel templates. The output of a Classic Chart Tag is always a bitmap image. The Tag Editor for Classic Chart Tags is the same as the advanced Tag Editor for Office Chart Tags, but it also contains formatting pages.

Native Microsoft Office Charts​

Native charts are regular Microsoft Office charts. The output of a native chart is an Office chart if the output format is the same as the template format. Otherwise the output is a bitmap image.

Charts in the template that are native Office charts rather than Chart Tags are included in the output if the following conditions are met:

  • If the output type matches the template type (DOCX, XLSX or PPTX), it's an Office chart and will appear exactly as it did in the template.
  • If the output format is not Office, it gives a close approximation and is rendered as a PDF chart.

Chart Tag Limitations​

Microsoft Office Chart Tags​

For an Office chart that is a Report Designer Chart Tag:

  • For DOCX, XLSX, or PPTX output, the chart will appear as it appeared in the template.
  • For non-DOCX output, the chart will be rendered as a bitmap chart.
  • Chart settings (e.g. currency symbols) are hard coded in the template and cannot be changed dynamically at run time.

Native Office Charts​

An Office chart that is not a Report Designer Chart Tag will be handled as follows:

  • Can be used in DOCX, XLSX, and PPTX templates, and the output format must match the template format (DOCX -> DOCX, XLSX -> XLSX, PPTX -> PPTX) to ensure the output matches the chart in the template.
  • For non-DOCX output, the chart will be rendered as a bitmap image.
  • Report Designer Chart Tags can only be used in XLSX templates on the same sheet as the chart.

Native Office Chart Types​

The following chart types added with the release of Excel 2016 are not supported in fluent:

  • Waterfall
  • Histogram
  • Pareto
  • Box & Whisker
  • Treemap
  • Sunburst
  • Radar (Spider Graph)
