Combined Chart

Combined charts are a versatile visualization that allow you to display multiple types of data series within a single chart, such as columns and lines together. You can use combined charts to compare different metrics while maintaining a shared axis for context. You can also create more complex comparisons by combining several chart types in one scenario. This article outlines the requirements for creating combined charts and provides guidance on key properties, data binding, and visual customization.

Data Binding

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 values plotted on the left vertical axis.

  • Ellipsis menu:

    • Data Format – Opens 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 type of chart 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 values plotted on the right vertical axis.

  • Ellipsis menu: Same as Left Value Axis.

• Axis (Category) – Drag a field here to define the categories along the horizontal axis.

• Legend (Series) – Drag a categorical field here to group data series.

  • Ellipsis menu:

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

• Trellis Columns – Drag a categorical field here to create a column-based small multiple layout. Each column displays a subset of the data based on the field value.

• Trellis Rows – Drag a categorical field here to create a row-based small multiple layout. Each row displays a subset of the data based on the field value.

• Tooltip – Drag one or more fields here to display additional information when a user hovers over a data point.

  • Ellipsis menu: Opens a settings window with a text editor to customize the tooltip content.

• Drill Down – Enables hierarchical exploration of data points.

  • Mode – Determines the drill-down method. Default is Default.

  • Dropdown options:

    • Pre-set Targets – When selected, opens a data binding slot to specify Drill Down Targets.

    • Pre-set Path – When selected, opens a data binding slot to specify Drill Down Paths.

Property Reference

Chart Style

Combined charts in Wyn can be extensively styled and configured using the Inspector panel. Below are key settings you can modify:

Maintain Color Assignments: Toggle this to True if you want to manually assign specific colors to individual data values instead of using automatic color mapping.

Palette: Lets you customize the color scheme applied to the chart. Use the dropdown to choose from available color palettes based on the current Theme.

Graph Opacity: Controls the transparency of the chart. Set to 0% for fully transparent or 100%for fully opaque.

Show Symbol – Toggles the display of symbols at each data point. When set to True, additional symbol properties appear:

• Symbol Shape – Choose the shape for the marker: Dot, Box, Triangle, Diamond, Plus, or X.

• Symbol Size – Specifies the size of the symbol in pixels. Enter a numeric value.

• Symbol Fill – Sets the fill color inside the symbol.

• Symbol Stroke – Sets the border color (stroke) around the symbol.

Line Style – Defines the curve or shape of the line. Choose from:

• Default – Straight lines between data points.

• Spline – Smooth, curved lines between data points.

• Step – Right-angled lines that connect points in a stepped pattern.

Line Type – Sets the visual style of the line. Choose Solid for an unbroken line or Dashed for a line made of dashes.

Line Thickness – Specifies the thickness of the line in pixels. Enter a numeric value.

Show Null As – Determines how the chart displays null (missing) values. Choose from:

• Connected – Joins the points on either side of the null value with a line.

• Gaps – Leaves an empty space where the null value occurs.

Axis (Category)

• Show Axis – Toggles the visibility of the X-axis. Default is On.

• Max Value / Min Value – Define the numeric upper and lower bounds for the axis scale. Leaving these blank allows the chart to automatically determine the range based on the data.

Legend

By default, the Show Legend toggle is set to False. To include a title for the legend, enable the Title toggle as well. Once enabled, the axis automatically takes the name of the data attribute it is bound to. To change that, you can enter a title in Custom Title. You can customize the title by setting the Font Family (e.g., Arial), Font Size, Text Color, Font Weight (such as bold), and applying Italic styling if desired.

The Position property allows you to position the legend title to the left, center, or right of the chart area.

The legend is set to Auto Size by default. To manually define the legend size, disable this setting by setting Auto Size to False. You can also control the Horizontal and Vertical Alignment, which are both set to Auto by default but can be changed using dropdown options. To allow legend labels to wrap across lines, set the Wrap Legend option to True.

The Click Action property defines how interactions with items in the chart legend affect the data displayed in the rose chart.

You can choose from two options in the dropdown menu:

• Select/Unselect

  When this option is selected, clicking a legend item highlights the corresponding data attribute on the chart and dims the others. This allows you to focus on a single series or category at a time. Clicking the legend item again restores the full view of all data attributes.

• Hide/Show

  When this option is selected, clicking a legend item temporarily hides the corresponding data attribute from the chart. Clicking it again redisplays the hidden data attribute. This is useful for quickly including or excluding specific data attributes without affecting the rest of the chart configuration.

Trellis

Use the Trellis properties when you create a Trellis Chart. This can be done in the Data Binding Tab. Drag and drop the attribute to Trellis.

You can set the Padding around the Trellis Chart to control the spacing between the chart content and its edges. You can also define a Trellis Border Color to outline each panel of the trellis. Additionally, the Trellis Font Settings allow you to customize the font family, size, color, weight, and style of the text used in the trellis layout.

Drill Down Setting

• Position – Determines where the drill-down navigation bar is displayed on the chart. Options include:

  • Top left (default)

  • Top center

  • Top right

  • Bottom left

  • Bottom center

  • Bottom right

• Home Name – Specifies the text label for the top-level view in the drill-down hierarchy. The default label is Home, but you can change it to something more descriptive, such as All Regions or Main Category.

• Font – Configures the font family, size, color, weight (e.g., bold), and style (e.g., italic) for all drill-down navigation text.

• Current Level Font Color – Sets the color for the label of the currently active drill-down level, helping it stand out from other levels.

• Other Levels Font Color – Sets the color for labels representing all non-active drill-down levels, allowing users to visually distinguish between the active and inactive levels in the navigation path.
