World Map¶

Introduction¶

"Guance" supports adding a world map to the view.

Application Scene¶

The world map of the Guance is used to display the data distribution of a certain metric data in different countries. It can be used in the following scene：

Showing the distribution of data in different regions
Show the data size ranking of different regions

Chart Search¶

Prerequisites: The metric query must contain the label "Country" in the dataset and the query criteria must include the group "Country", otherwise the chart cannot be added successfully

Please click chart-query for detailed explanation of chart query conditions, simple query is added by default. You can add multiple queries, but the Tag of by (grouping) must be the same, modify one, and the other will be modified automatically.

The chart query matches regions by country and colors by metric values, as explained below：

Options	Description
Country tag	Select the tag that represents the country, the tag must be the tag tag that has been grouped in the query (Note: the tag name of the country tag does not have to be "country", as long as the value is the country )
Metrics	When multiple metric queries are added, you can set the main metric to be displayed. "Main display metric" is the metric that determines the gradient color of the color block

Chart Links¶

Links can help you jump from the current chart to the target page, support adding internal links and external links to the platform, and support modifying the corresponding variable values in the links through template variables to transfer the data information to complete the data linkage. Please click chart-link to view the related settings.

Chart Style¶

Options	Description
Chart Title	Set the title for the chart, after setting, it will be displayed on the top left of the chart, and it supports hiding
Region Ranking	Support ranking by region data size, from largest to smallest. Disable by default
Color	1. Gradient color system: Gradient color of the color block. After selecting the color, the system will use the selected color as the base to generate the number of color blocks of the selected grade 2. Gradient interval： Automatic: default divided into 5 intervals according to the maximum and minimum values of the current data, supports customizing the maximum and minimum values； Customization: Supports customizing the gradient color levels, i.e. the level settings of the area range in the map. By default, the system divides the maximum and minimum values of the selected metric into 5 gradient levels, and supports customizing the number of levels (up to 10), the range of levels, and the display color

Chart Setup¶

Basic Settings¶

Options Description

Units 1. Support setting units for query results.
1）If the queried data has no unit, after setting the unit in the chart, it will be displayed on the chart according to the set unit
2）If the query data comes with its own units, or if you are in [Metric Management] (../../metrics/dictionary.md), and you set the units for the metrics in the chart, the units set in the chart will be displayed on the chart.
3）If the query data has no units and no units are set in the chart, the chart Y-axis values are automatically calculated according to scientific notation; the original values are displayed on the chart in the format [thousandths] (chart-query.md#thousand).
Scientific counting instructions
Default query result value is automatically converted to units, display follows 「scientific notation K, M, B」 (1 thousand = 1K, 1 million = 1M, 1 billion = 1B), retaining two decimal points; RMB is automatically converted to units 「yuan, million, billion」, retaining two decimal points
For example, if the unit of time interval is selected as ns, then according to the size of the data, the query result will only automatically convert the unit effect as follows, and so on：
1000000ns：Chart query data results in 1ms
1000000000ns：The chart query data result shows 1s
10000000000ns：The chart query data result shows 1m

2.Support for query results preset units, manual input format: aggregation function (metric), such as last(age_idle)

Advanced Settings¶

Options	Description
Time Slicing	When time slicing is enabled, the original data will be aggregated in segments at certain time intervals, and then the aggregated data set will be aggregated for the second time to get the result value, which is disabled by default. For details, please refer to time slicing description
Lock Time	Support to lock the time range of chart query data, not limited by the global time component. The time set by the user will appear in the upper right corner of the chart after successful setup, such as 【xx minutes】, 【xx hours】, 【xx days】. If you lock the time interval of 30 minutes, then when you adjust the time component, no matter what time range view is queried, only the last 30 minutes data will be displayed.
Time interval	If time slice is off, there is no time interval option, if time slice is on, the time interval option is as follows： Original interval: default query to display data according to the time range of the time component Auto-alignment: When turned on, the query will be dynamically adjusted according to the selected time range and aggregation interval, rounded up according to the calculated time interval. (For example, if the automatic aggregation algorithm calculates the time interval to be 50 seconds, then the actual query will be launched according to the time interval of 1 minute) The system presets 1 ms, 10 ms, 50 ms, 100 ms, 500 ms, 1 second, 5 seconds, 15 seconds, 30 seconds, 1 minute, 5 minutes, 10 minutes, 30 minutes, 1 hour, 6 hours, 12 hours, 1 day, 1 week, 1 month, and many time interval. Custom time interval: When 【Lock time】 is selected, according to the length of the lock time, different optional time intervals will be automatically matched to query the displayed data. (For example, if you select 1 minute as the time interval, the query will actually be launched at the interval of 1 minute)
Field Mapping	Object mapping with view variables, default is off, if object mapping is configured in view variables： When field mapping is enabled, the chart displays the 「grouped fields」 of the query and the corresponding 「mapped fields」, and the unmapped grouped fields are not displayed. When field mapping is turned off, the chart is displayed normally, without the mapped fields
Chart Linkage	Linkage between map and view variables. When enabled, select the view variables to be linked, then when you click on the map color block area, the view variable value will automatically change to the selected area value
Chart Description	Add description information for the chart, after setting the chart title will appear behind the 【i】 prompt, if not set, it will not be displayed
Workspaces	A list of authorized workspaces, which can be queried and displayed via a chart after selection
