Bubble Charts - Quick BI - Alibaba Cloud Documentation Center

A bubble chart is a data visualization that shows the relationship between multiple variables. It uses the position and size of bubbles in a two-dimensional coordinate system to display data. This topic describes how to add data to a bubble chart and configure its style.

Example

Configure Data

In the Charts section of the widget library, drag Bubble Chart to the canvas.

On the Data panel, select a dataset. On the Fields tab, configure the chart fields as described in the following table.

Field	Description
X-axis/Dimension or Measure	Configures the data for the x-axis. You can drag a dimension or measure field to this section. In the example, the Order amount field is used. This means the position of each bubble on the x-axis depends on its order amount.
Y-axis/Measure	Configures the data for the y-axis. Only measure fields are supported. The y-axis works with the x-axis to determine the exact position of each bubble in the coordinate system. In the example, the Profit amount field is used. This means the position of each bubble on the y-axis depends on its profit amount.
Category/Dimension	Configures the dimension used to categorize the data. This lets you compare and observe the distribution of different data categories. In the example, the Region field is used. This means the data is grouped by region.
Color/Dimension or Measure	Configures the field that determines the bubble color. You can drag a dimension or measure field to this section. You can then customize the bubble colors in the Plotting Area > Color Settings section on the Style tab. Note You can configure this field only if a field is already present in the Category/Dimension section. If you use a dimension field, a different bubble color is generated for each dimension value. For example, if you use the Region field, bubbles for the Northeast region are displayed in blue. If you use a measure field, a color gradient is generated based on the trend of the measure values. For example, if you use the Order quantity field, the bubble color changes from dark to light based on the order quantity. In the example, the Region field is used. This means different bubble colors represent different regions.
Shape/Dimension	Configures the field that determines the bubble shape. Only dimension fields are supported. You can customize the bubble shape in the Plotting Area > Bubble Style section on the Style tab. Note You can configure this field only if a field is already present in the Category/Dimension section. In the example, the Product type field is used. This means different bubble shapes represent different product types.
Size/Measure	Configures the field that determines the bubble size. Only measure fields are supported. The system generates the bubble size based on the measure value. In the example, the Order quantity field is used. This means the bubble size is determined by the order quantity.
Playback Axis/Time Dimension	If your data includes time information, you can drag a time field here to create a dynamic bubble chart that changes over time. This is not used in the example.
Tooltip/Measure	When a report viewer hovers the mouse pointer over a bubble, a tooltip appears to provide more details about that data point, such as the specific value of a measure. You can configure the specific measure information to display in the tooltip. In the example, the Shipping cost field is used. This means the shipping cost for the data point is displayed in the tooltip.

You can also perform the following data operations:

Configure Styles

Position and Size

You can configure the following settings for the widget:

Adjust the widget alignment (①). Options include align left, center, and align right.
Adjust the widget position (②). Set the X and Y coordinate values, using the upper-left corner as the origin.
Adjust the widget angle (③). Set the rotation angle.
Adjust the widget size (④). Set the width (W) and height (H) of the widget.
Lock the widget (⑤). When a widget is locked, its size cannot be adjusted.
Set the opacity of the widget (⑥).

Plotting Area

In the Plotting area section, you can configure the Color Scheme, Bubble Style, and Enable Four Quadrants settings. The available configuration items vary depending on the fields that are configured in the Fields tab.

If a field is configured in the Shape/Dimension section, the following settings are available.

Configuration item	Description
Color Settings	Sets the overall color scheme for the bubbles in the chart. You can select a built-in system theme and customize the color for individual dimension values. When a measure field is configured in the Color/Dimension Or Measure section, you must set the Data Mapping Range and Color Scheme for the measure.
Fill Opacity	Sets the opacity of the bubbles.
Bubble Style	Sets the style of the bubble shapes. You can select from materials or use an image field. Material: Set a different shape pattern for each dimension value. You can select from built-in materials or upload a custom image. Image field: Uses images from an image field in the dataset as the fill. You can use the Image Field option only if the dataset contains an image field and the field type is image (). When you upload a custom image or use an image field, you can also set the image shape and display mode.
Bubble Size	Sets the size of the bubbles.
Show Border	Sets whether to show a border for the bubbles.
Show Shadow	Sets whether to show a shadow for the bubbles.
Four Quadrants	You can enable the Four Quadrants feature when both the x-axis and y-axis fields are measure fields.

If no field is configured in the Shape/Dimension section, the following settings are available.

Configuration item	Description
Color Settings	Sets the overall color scheme for the bubbles in the chart. You can select a built-in system theme and customize the color for individual dimension values. When a measure field is configured in the Color/Dimension Or Measure section, you must set the Data Mapping Range and Color Scheme for the measure.
Fill Opacity	Sets the opacity of the bubbles.
Bubble Style	Sets the shape style for all bubbles in the chart. You can select a built-in icon or upload a custom image. When you upload a custom image, you can also set the image Shape and Display Mode.

You can enter the number of divisions, and the system will automatically distribute the tick marks evenly on the left y-axis.

Legend

In the Legend section, you can configure the legend items, position, and text style.

Data Labels

In the Data Labels section, you can perform the following operations.

Show Data Labels: Sets whether to display data labels in the chart.
Show All: Sets whether to display all data labels. If the chart has many measure values, we recommend that you do not select this option. In this case, the system displays only some data labels to prevent the chart from becoming cluttered.

Note

The Position cannot be adjusted when a field is added to the Playback Axis/Time Dimension section.

Tooltip

Select Autoplay On Page Load to automatically play the chart animation once when the report loads.
Select Loop Playback to play the chart animation in a loop.
Select Show Current Time Value to display the corresponding time as the chart animation plays.
Select Enable trail rendering to draw the trail of a bubble when it is clicked. The trail follows the playback axis sequence.
