Bubble Chart

Prerequisites

A dashboard is created. For more information, see Create a dashboard.

Overview

• Scenarios

  Two sets of data generate multiple coordinate points. You can observe the distribution of these points to determine whether a correlation exists between variables or to summarize the distribution pattern.

  Purpose: A bubble chart provides the following key information:

  • Whether a quantitative correlation exists between variables.

  • Whether the correlation is linear or curved.

  • Whether outliers exist. An outlier is a point that deviates from most points. You can analyze outliers to determine whether they significantly impact the population during modeling analysis.

• Benefits

  • Computing capability: The conversion rate is computed automatically.

  • Data visualization: A bubble chart can be displayed dynamically based on the data timeline.

• Example

Limitations

A bubble chart is configured with the following fields: Y-axis / measure, X-axis / dimension or measure, Category / dimension, Color / dimension or measure, Size / measure, and playback timeline / time dimension.

• The Y-axis requires one measure.

• The X-axis requires one dimension or one measure.

• The category requires one dimension.

• Color requires a dimension or a measure. The field can be the same as the one used for the X-axis, Y-axis, or category.

• Size requires one measure. The field can be the same as the one used for the Y-axis.

  If the X-axis uses a measure field, the same field can also be used for Size.

• The playback timeline requires a dimension. You can add only one dimension, and it must contain date information.

  Note

  You can enable the playback timeline only when both the X-axis and Y-axis use measure fields.

Configure Chart Data

1. On the Data tab, select dimensions and measures based on your business requirements.

   • In the Measures list, find "Profit Amount" and double-click or drag it to the Y-axis / measure area.

   • In the Measures list, find "Order Amount" and double-click or drag it to the X-axis / dimension or measure and Size / measure areas.

   • In the Dimensions list, find "Province" and double-click or drag it to the Category / dimension area.

   • In the Dimensions list, find "Region" and double-click or drag it to the Color / dimension or measure area.

   • (Optional) To assign a different shape to each dimension value, drag a field to the Shape / dimension area. You can then customize the bubble shape for each dimension value in the Style pane. For this example, drag the Product Type field to assign a unique shape for each product type.

     Note

     This option is available only when a field is present in the Category / dimension area.

2. Click Update. The chart updates automatically.

Configure the Style of a Bubble Chart

For information about general chart style settings, see Configure the chart title area.

You can use the search box at the top of the configuration pane to find a specific option. You can also click the icon to Expand/Collapse all categories.

Chart Area

In the Chart area section, you can configure the color scheme and bubble size, and enable the four-quadrant feature. The available options vary depending on the field configurations.

• If a field is configured in the Shape / dimension area, the following options are available.

  Parameter	Description
  Color settings	Sets the color scheme for the bubbles. You can choose from built-in system themes and customize the color for individual dimension values. If the Color / dimension or measure area contains a measure field, you must configure the data mapping segments for the measure.
  Fill opacity	Sets the transparency of the bubbles.
  Bubble style	Sets the bubble shape style. You can use assets or an image field. Asset: Assign a different shape to each dimension value. You can select from built-in assets or upload a custom image. Image field: Selects an image from an image field in the dataset to use as a fill. You can use the Image field only when the dataset contains an image field and the field is of the image type (). When you upload a custom image or use an image field, you can also set the shape and display mode of the image.
  Bubble size	Sets the size of the bubbles.
  Show border	Specifies whether to show a border around the bubbles.
  Show shadow	Specifies whether to show a shadow for the bubbles.
  Four-quadrant	You can enable the four-quadrant feature when both the X-axis and Y-axis use measure fields.

• If no field is configured in the Shape / dimension area, the following options are available.

  Parameter	Description
  Color settings	Sets the color scheme for the bubbles. You can choose from built-in system themes and customize the color for individual dimension values. If the Color / dimension or measure area contains a measure field, you must configure the data mapping segments for the measure.
  Fill opacity	Sets the transparency of the bubbles.
  Bubble style	Sets a uniform shape for all bubbles. You can select a built-in icon or upload a custom image.
  Bubble size	Sets the size of the bubbles.
  Show border	Specifies whether to show a border around the bubbles.
  Show shadow	Specifies whether to show a shadow for the bubbles.
  Four-quadrant	You can enable the four-quadrant feature when both the X-axis and Y-axis use measure fields.

Axes

In the Axes section, configure the axis styles.

Legend

In the Legend section, click the icon to enable the chart legend and configure its style.

Data Labels

In the Data labels section, set the visibility, position, and style of data labels.

Tooltip

In the Tooltip section, configure whether to show tooltip content and set its style.

Series Settings

In the Series settings section, configure the series style.

Auxiliary Display

In the Auxiliary display section, configure the playback timeline:

• Select Auto Playback When Page Loads to automatically play the chart animation once when the report loads.

• Select Loop to play the chart animation repeatedly.

• Select Show Current Time Value to display the corresponding time value during the animation.

• Select Enable Trajectory Drawing to trace a clicked bubble's trajectory along the playback timeline.

Configure Chart Analysis

What to do next

• You can share the dashboards that you created. For more information, see Share a dashboard.

• If you need a complex navigation menu for thematic analysis, you can integrate your dashboards into a BI portal. For more information, see Create a BI portal for PC.
