Quick BI:Bubble Chart

Prerequisites

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

Overview

• Scenarios

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

  Purpose: You can use a bubble chart to easily obtain the following key information:

  • Whether a quantitative correlation exists between variables.

  • Whether the correlation is linear or curved.

  • Whether outliers exist. An outlier indicates a point that deviates from most points. You can further analyze these outliers to determine whether they have a significant impact on the population during modeling analysis.

• Benefits

  • Computing capability: The conversion rate is automatically computed.

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

• Example

Configure a bubble chart

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

   • In the measure list, double-click order_number. You can also drag this measure to the Y axis (Mea.) field.

   • In the measure list, double-click price. You can also drag this measure to the X axis (Dim. or Mea.) and Size (Mea.) fields.

   • In the Dimension list, double-click product_type. You can also drag this dimension to the Category (Dim.) field.

   • In the Dimension list, double-click area. You can also drag this dimension to the Color (Dim. or Mea.) field.

   • In the Dimension list, double-click order_date(year). You can also drag this dimension to the Playback Timeline/Time Dimension field.

2. Click Update to update the bubble chart.

3. Auto Refresh

   After you select Auto Refresh, the system refreshes the bubble chart as scheduled. For example, if you select Auto Refresh, enter 5, and then select Minutes, the system refreshes the bubble chart every 5 minutes.

Configure the style of a bubble chart

• In the Basic Information section, set the following parameters:

  1. Show Title and Description and custom header style

  2. Show Link

  3. Description

  4. Footer

  ⑤ Component container

  ⑥ Card spacing

• In the Chart Style section, set the Show Chart Labels, Show Legend, Color, and Bubble Size parameters.

  The Color parameter is displayed only when Color (Dim. or Mea.) is specified on the Data tab.

  • If you specify a dimension for Color (Dim. or Mea.), you can select a color series or set colors for different field values.

  • If you specify a measure for Color (Dim. or Mea.), you must configure the Data Mapping Segments parameter before you set color for different segments.

• In the Axes section, configure the style of the axes. The following table describes the parameters.

  Parameter	Parameter	Description
  X-axis	Axis Title	The title for the x-axis.
  	Unit	The unit for the x-axis.
  	Show Title and Unit	Specifies whether to show the title and unit of the x-axis.
  	Show Axis	Specifies whether to show the x-axis. If you select Show Axis, you can specify the line style, line width, and color of the x-axis.
  	Show Value	Specifies whether to show values on the x-axis. If you select Show Value, you can specify the font type, font size, and color of values.
  	Gridlines	Specifies whether to show gridlines on the x-axis. If you select Gridlines, you can specify the line style, line width, and color of gridlines.
  	Show Scale	Specifies whether to show scales on the x-axis.
  Left Y-axis	Axis Title	The title for the left y-axis.
  	Unit	The unit for the left y-axis
  	Minimum and Maximum	The minimum and maximum values on the left y-axis. Note If you select Default, the minimum and maximum values are automatically displayed on the left y-axis. If you clear Default, you need to manually configure the minimum and maximum values on the left y-axis.
  	Auto Magnify Value Differences	Specifies whether to magnify the value differences on the left y-axis. Note If Auto Magnify Value Differences is selected, the axis range is adjusted based on the minimum and maximum values of the displayed data.
  	Show Title and Unit	Specifies whether to show the title and unit of the left y-axis.
  	Show Axis	Specifies whether to show the left y-axis. If you select Show Axis, you can specify the line style, line width, and color of the left y-axis.
  	Y-axis Label Settings	The display formats for labels on the left y-axis. Valid values: AutoFit, Customer, and Manual. Note You can also configure multiple measure display formats at a time on the Data tab. For more information, see Configure a chart.
  	Show Value	Specifies whether to show values on the left y-axis. If you select Show Value, you can specify the font type, font size and color of values.
  	Gridlines	Specifies whether to show gridlines on the left y-axis. If you select Gridlines, you can specify the line style, line width, and color of gridlines.
  	Show Scale	Specifies whether to show scales on the left y-axis.
  	Label and Scale Range	You can set the Maximum /Minimum value of the left Y-axis label and scale range based on Automatic or Manual Settings.

  Note

  If you select Dual Y-Axis in the Chart Style section, you also need to configure the Right Y-axis. The parameter configurations on the Right Y-axis are the same as those on the Left Y-axis tab.

• In the Functionality section, select Enable Four-quadrant and set the displayed parameters.

  Note

  You can enable the four-quadrant feature only when both Y axis (Mea.) and X axis (Dim. or Mea.) are specified with measures.

• When you configure Playback Timeline Settings, take note of the following items:

  • If you select Auto Playback When Page Loads, the animation of the bubble chart is automatically played after the page is loaded.

  • If you select Loop, the animation of the bubble chart is played repeatedly.

  • If you select Show Current Time, time is displayed during the playback.

  • If you select Enable Trace Drawing, you can click a bubble to draw its trace in the order of the playback axis.

• In the Series Settings section, configure Series and Display Name.

Configure advanced settings

Limits

When you create a bubble chart, you must specify Y axis (Mea.), X axis (Dim. or Mea.), Category (Dim.), Color (Dim. or Mea.), Size (Mea.), and Playback Timeline/Time Dimension.

• You can specify only one measure for Y axis (Mea.).

• You can specify only one measure or one dimension for X axis (Dim. or Mea.).

• You can specify only one dimension for Category (Dim.).

• You can specify only one measure or one dimension for Color (Dim. or Mea.). The dimension or measure that you specified for Color (Dim. or Mea.) can be the same dimension or measure that you specified for X axis (Dim. or Mea.), Y axis (Mea.), and Category (Dim.).

• You can specify only one measure for Size (Mea.). The measure that you specified for Size (Mea.) can be the same measure that you specified for Y axis (Mea.).

  If you specify a measure for X axis (Dim. or Mea.), you can also specify this measure for Size (Mea.)

• You can specify only one dimension for Playback Timeline/Time Dimension. The dimension must be a time field.

  Note

  Playback Timeline/Time Dimension is applicable only when you specify measures for both Y axis (Mea.) and X axis (Dim. or Mea.).

What to do next

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

• If you want to create a navigation menu for thematic analysis, you can integrate a dashboard into the business intelligence (BI) portal. For more information, see Create a BI portal.
