A treemap chart is a data visualization tool that you can use to display the relationship between parts and the whole and the comparison between parts. This topic describes how to configure a treemap chart.
Overview
A treemap chart includes multiple rectangles that represent data sizes. A larger rectangle represents a higher proportion of categorical data.
The rectangles in a treemap chart are sorted.
Configuration example
In the left-side navigation pane, click Log Storage. In the Logstores list, click the logstore you want.
In the left-side navigation pane, choose Dashboard > Dashboards. In the dashboard list, click the dashboard you want. In the upper-right corner of the dashboard page, click Edit. In edit mode, click Add > Add Chart.
On the right side of the Edit Chart page, select Treemap Chart Pro in the Chart Types section and configure the Title parameter in the Basic Configurations section. On the left side of the Edit Chart page, configure the query time range, Logstore, and query statement for the chart. After you complete the configuration, click Apply in the upper part of the Edit Chart page to view the configuration effects of the treemap chart.
The following query statement is used to query the distribution of events by region:
* | select "event.acsRegion" as region, count(1) as cnt group by region order by cnt DESC limit 20

Parameters in the Variable Replacement section
Parameter
Description
Variable Replacement
The settings for variable replacement. You can click AddVariable Replacement to add a filter of the Variable Replacement type to the treemap chart. After you configure the settings for variable replacement on the General Configurations tab, Simple Log Service adds a filter in the upper-left corner of the treemap chart. You can select a value from the filter drop-down list. After you select a value, Simple Log Service automatically replaces the variable in the query statement of the treemap chart with the variable value indicated by the value that you select, and performs a query and analysis operation. For more information, see Example 2: Configure variable replacement.
Parameters in the Documentation section
Parameter
Description
Add Documentation Link
The button that allows you to specify custom document links and descriptions. After you configure the settings, the specified information is displayed in the upper right corner of the treemap chart.
Configuration on the Field Configuration tab
You can configure personalized display settings for the results of a single query statement or for a single column of data in the results. For more information, see Configuration on the General Configurations tab.
For example, you can select A > cnt to configure settings for the cnt field in the query results of Query Statement A. In the following figure, the unit of the cnt field is set to number.
Configuration on the Interaction Occurrences tab
You can configure an interaction occurrence for the results of a single query statement or for a single column of data in the results to analyze data in a finer-grained manner. Supported types of interaction occurrences include Open Logstore, Open Saved Search, Open Dashboard, Open Trace Analysis, Open Trace Details, and Create Custom HTTP URL. For more information, see Interaction occurrences.
For example, in the A section, you can configure an Open Logstore interaction occurrence for the results of Query Statement A. After you configure the interaction occurrence, you can click a point in the treemap chart and click Open Logstore. Then, you are navigated to the Logstore that you specify.
