Combo charts

Combo charts are a type of visualization that uses a mixture of chart types. Sigma combo charts support bars, lines, areas, and scatter plots.

Requirements

• You must be assigned an account type with the Edit Workbook and/or Explore Workbook permission enabled.
• You must be the workbook owner or be granted Can explore or Can edit workbook permission.

🚧

If you're granted Can explore access to the workbook, you can create and modify visualization properties and formatting in Explore mode, but you cannot publish your changes.

Plot a combo chart

Visualizations can be created via the PAGE ELEMENTS section of your workbook's editor panel or directly from an existing data element.

Visualized data does not display on the page canvas until all required plot fields are defined.

Add columns to available plot fields using either the field's + menu or dragging and dropping the column.

Fields

• X-AXIS (1 column)
  Data is first grouped by the column on the X-AXIS.
• Y-AXIS (1+ columns)
  Columns added to the visualization’s Y-AXIS are aggregated by default. Aggregation type (e.g. Sum vs Count) is dependent on the original column’s value type.
  By default, the first column placed on the y-axis is displayed as a bar chart, and all additional columns are plotted as lines. However, each plotted column's SHAPE can be set to any of four options – bar, line, area, or scatter – from its column menu (see Change the chart type for a plotted column).

Marks

• Color
• Tooltip (1+ columns)
• Trellis (1+ columns)
