Statistical Charts

After logs are reported to LTS, you can search for key log data using SQL analysis syntax and view the results in charts. This helps you track log data trends effectively. You can also save chart analysis results to the dashboard for long-term monitoring.

Constraints

Up to 100 charts can be created for a log stream.
Up to 50 charts can be added to a dashboard.

Statistical Chart Types

Data in different scenarios can be displayed in table charts, bar charts, and line charts. For details, see Table 1.

**Table 1** Chart types
Chart Type	Scenario
Table chart	A table chart is the most common way for data display. Data can be collected and compared through data structuring. This chart type is applicable to most scenarios.
Bar chart	A bar chart describes the classified data and intuitively compares the size of each classification item. This chart type is applicable to classified statistics, such as the number of occurrences of each error code type in the past day.
Line chart	A line chart requires the time sequence field to organize and aggregate metrics based on the time sequence. This chart type intuitively reflects the changes of metrics over time.
Pie chart	A pie chart shows the proportion of each category. The proportion of each category is measured by the sector size. This chart type is applicable to scenarios such as error code proportion analysis.
Number chart	A number chart describes a single metric. Generally, key metrics with business value are selected. This chart type is applicable to single-metric statistics such as daily, weekly, monthly PVs and UVs.
Digital line	A digital line chart combines a line chart and a number chart. The line chart displays data trends and changes, and the number chart displays key metrics. This chart type is applicable when trends and key data points need to be displayed at the same time.
Map	A map displays the geographical location of data based on the location of a chart. Generally, a map displays the distribution of data in different geographical areas. This chart type is applicable to geographical location statistics, such as geographical distribution of attack IP addresses.
Funnel chart	A funnel chart is applicable to the service procedure with a single flow direction and a single path. The funnel chart collects statistics on each phase and uses a trapezoidal area to indicate the difference between the service volume of a phase and that of the previous phase.
