Combined Charts are a visualization used to display multiple chart types in a single view, allowing you to compare different data series with distinct scales or measurement units. They are especially useful when you need to show relationships between two related measures — for example, displaying Sales as columns and Profit Margin as a line on the same chart.

You can use combined charts to visualize Sales and Profit Trends — show total sales as columns and profit margin as a line, Production Output and Costs — compare units produced to total cost across time periods, Website Performance — plot page views against conversion rate on separate axes.

This article explains the requirements for creating combined charts and provides an overview of key properties and configuration options available in Wyn Notebooks.

This topic explains how to create and customize data tables and explains the most frequently used properties. Refer to the reference for all the column chart properties and configuration options.

Create a Combined Chart

To create a combined chart, click on the Plus (+) button, opening the dropdown from which you can select your chart.

Bind Data to Combined Chart

The Data Binding tab allows you to assign data fields to the combined chart elements and configure how the data is displayed.

Left Value Axis

Drag a numeric field here to define the measure plotted on the left vertical axis.

Use this axis for your primary measure — for example, Sales Amount or Revenue.

Ellipsis Menu Options (⚙):

Data Format: Open the data format dialog to customize number formatting.
Display Unit: Choose how values are scaled — Auto (default), None, Thousands, Millions, Billions, or Trillions.
Chart Type: Select the chart type for the left axis: Line Chart, Column Chart, Area Chart, or Stacked Column Chart.
Scale: Choose the axis scale. Default is Linear.

Right Value Axis

Drag a numeric field here to define the measure plotted on the right vertical axis.

Use this axis when the second measure has a different unit or scale — for example, Profit Margin (%) or Conversion Rate.

Ellipsis Menu Options (⚙): Same as the Left Value Axis.

Axis (Category)

Drag a categorical or time-based field here to define the categories displayed along the horizontal axis.

Common examples include Month, Quarter, Region, or Product Category.

Legend (Series)

Drag a categorical field here to group data into multiple series. Each unique value in this field creates a separate line or column within the chart.

Ellipsis Menu Options (⚙):

Axis: Select which value axis to associate the series with — Default, Left Value Axis, or Right Value Axis.

This is useful for mixing visual types (for example, displaying Sales as columns on the left axis and Profit Margin as a line on the right axis).

Trellis Columns

Drag a categorical field here to create a column-based small multiples layout. Each column displays a subset of the data corresponding to a unique field value.

For example, binding Region to Trellis Columns will generate one chart per region arranged horizontally.

Trellis Rows

Drag a categorical field here to create a row-based small multiples layout. Each row displays a subset of the data for a particular category.

For example, binding Product Category to Trellis Rows will generate one chart per category arranged vertically.

Drag one or more fields here to display additional details when hovering over a data point.

Tooltips provide contextual information (e.g., Exact Sales Value or Profit Margin) without cluttering the visual.

Ellipsis Menu Options (⚙): Opens a settings dialog where you can customize tooltip content using a text editor.

Drill Down

The Drill Down slot enables hierarchical exploration of your data.

Users can click on a data point to drill deeper into more detailed levels (for example, from Year → Quarter → Month).

Mode Options:

Default: Standard drill-down interaction.
Pre-set Targets: Opens a slot to specify Drill Down Targets.
Pre-set Path: Opens a slot to specify Drill Down Paths.
