Quick BI:Bubble Chart

Prerequisites

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

Overview

• Use 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 parameters on the data tab

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

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

   • In the Measures list, double-click orderamt. You can also drag orderamt to the x-axis /Dimensions or Measures and Dimensions /Measures fields.

   • In the Dimensions list, double-click province. 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.

2. Click Update to update the bubble chart.

Configure the style of a bubble chart

The following section describes how to configure the styles of an LBS heat map. For information about the common style settings of charts, see Configure the chart title.

You can enter a keyword in the search box at the top of the configuration section to quickly find configuration items. You can click the chart on the right to expand /collapse all categories.

• In the drawing area, configure Color, Bubble Size, and Enable Quadrant.

  • If you set the Color /Dimension or Measure parameter to Measure, you must set the Data Mapping Range parameter for the Measure parameter.

    

  • If both the x-axis and Y-axis fields are measures, you can enable the Four Quadrant feature.

    

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

  Parameter	Parameter
  X-axis	Display x-axis	Set whether to display x-axis.
  	Show Title and Unit	Specifies whether to show the title and unit of the X-axis.
  	Show Value	Specifies whether to show values on the X-axis.
  	Minimum and Maximum	The minimum and maximum values on the x-axis. Note If you select Default, the minimum and maximum values are automatically displayed on the axis. If you clear Default, you can manually configure the minimum and maximum values on the axis.
  	Y-axis Label Settings	The display formats for labels on the left y-axis. Options: 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.
  	Gridlines	Specifies whether to show gridlines on the X-axis, including the line style, line width, and color of the X-axis.
  	Show Axis	Specifies whether to display the left Y-axis, including line style, line width, and color of the left Y-axis.
  	Show Scale	Specifies whether to show scales on the X-axis.
  Left Y-axis	Show Left Y-Axis	Set whether to display the left Y-axis.
  	Show Title and Unit	You can set Axis Title and Unit. You can select Axis Outside or Axis Above.
  	Show Value	Specifies whether to show the label values on the left Y-axis.
  	Minimum and Maximum	Specifies whether to show the minimum and maximum values on the left Y-axis. If you select Default, the minimum and maximum values are automatically displayed on the axis. If you clear Default, you must manually configure the minimum and maximum values on the axis.
  	Show Axis	Specifies whether to display the left Y-axis, including 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. Options: 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.
  	Gridlines	Specifies whether to show gridlines on the left Y-axis, including the line style, line width, and color of the left Y-axis.
  	Show Scale	Specifies whether to show scales on the left y-axis.
  	Axis Value Range and Interval	You can set the Maximum /Minimum value of the left Y-axis label and scale range based on Automatic or Manual Settings. You can set the Custom Interval to By step size or By Equal Number.

• In the Legend section, configure Legend Position and Text Style.

  

• In the label, set whether to display the label, location, and label style.

  

  Note

  When you drag a playback axis or time dimension to a field, you cannot adjust the position.

• In the ToolTip section, set Whether to Show, Display Mode, Background Color, and Text Style.

  

• In the Series Settings section, you can configure the series.

  

• In the Auxiliary Display section, set the Playback Axis parameter.

  • 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.

Chart analysis configuration

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. Show grid lines Set whether to show grid lines on the axis, including line type, line width, and color
