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

  • To create a data element, you must have Can Edit access to the individual workbook and be in Edit mode.
  • Many exploratory actions are also supported in Explore mode; see Workbook modes.

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 will not display on the page canvas until all required plot fields are defined.

Add columns to open 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 a Column's Shape).
