Simple Log Service allows you to visualize query and analysis results on charts.
Before you can use charts, you must configure indexes and enable the analysis feature. To enable the analysis feature, turn on Enable Analytics for the fields that you want to analyze in the Search & Analysis panel. For more information, see Create indexes.
Simple Log Service displays query and analysis results on charts only after you execute query statements. A query statement must be in the search statement|analytic statement format.
Charts are used to display query and analysis results. On the Graph tab, you can select a chart in the chart type section and configure the chart based on your business requirements.
Select a chart
On the Graph tab, you can select a chart type to display the query and analysis results.
On the Common Settings tab, you can configure global settings for a chart. For example, you can select a color scheme to display the results of all query statements for the chart.
On the Fields tab, you can configure custom display settings for the result of a query statement or for the data of a column in the result. For example, if you select a query statement and then select a color scheme, the chart is generated based on the result of the query statement and uses the color scheme that you select.
You can configure an interaction occurrence for the result of a query statement or for the data of a column in the result to analyze data from a fine-grained dimension.
Upgrade a chart
Simple Log Service provides the following versions of charts: Pro and Standard. Compared with charts (Standard), charts (Pro) provide better visualization capabilities. Simple Log Service provides the one-click migration feature to upgrade charts (Standard) to charts (Pro).
After you convert a chart (Standard) to a chart (Pro), you cannot convert the chart (Pro) to a chart (Standard).
What do I do if no charts are automatically generated when I execute query statements?
When you execute multiple query statements in sequence, the Value Column, X Axis, or Y Axis configurations are not automatically modified based on the current query statement. The X-axis and Y-axis configurations may remain the same as the configurations of the previous query statement. In this case, the query and analysis result of the current query statement cannot be automatically displayed on a chart. The following errors may occur:
The selected dimensions are not in the query results. Check and modify the Properties settings.
X Axis or Y Axis is unavailable. Check and modify the Properties settings.
Modify the Properties settings of the chart based on the current query statement.
