Word Cloud

Version

Application Scenario

The word cloud is a visual representation of text and data indicating the importance of each word by font sizes or color shades.

It is suitable for presenting large amounts of text and data, such as the data analysis of keyword searches. Data analysis is recommended when there are more than 30 entries. The following figure shows the display effect.

Chart Feature

Advantage: The word cloud can visually display the frequency of the data based on the size of the keywords, and can show the proportionate difference between the data in a more obvious way.

Disadvantage: The word cloud cannot visually display the change rule of data, and it cannot display keywords dynamically.

Data

The following figure shows the settings of binding data to the word cloud.

Data Source: Dataset Data and Cell Data are available for the word cloud. 

Index Name: Enter custom text as Index Name. Tick Index Name when using data point prompts, and it will prompt the text information when the cursor hovers over the keyword.

Name: The name of the word to be displayed.

Value: The value corresponding to the word name, or the occurrence frequency of the word, determines the size of the displayed word name.

Summary: You can select First, Last, Sum (default value), Average, Maximum, Minimum, or Count.
