This topic describes the common syntax of Markdown charts and how to manage a Markdown chart on a dashboard of Log Service.

Prerequisites

Background information

Notice The Markdown chart feature is temporarily unavailable.

Log Service allows you to add multiple charts to a dashboard. This way, you can view analysis results in an efficient manner and monitor the status of multiple applications on a single dashboard. Log Service also allows you to add Markdown charts to a dashboard. You must edit Markdown charts by using the Markdown syntax. You can insert multiple elements, such as images, links, and videos, into Markdown charts to make your dashboard page more user-friendly.

You can create different Markdown charts based on your business requirements. Markdown charts can make a dashboard more intuitive to use. You can insert text, such as background information, chart descriptions, notes, and extension information, into Markdown charts to optimize the effectiveness of information presentation. You can insert saved searches or the dashboard links of other projects to navigate to other query pages. You can insert custom images and videos to enrich your dashboard information.

You can insert the custom links of other dashboard pages for the current project into Markdown charts to navigate to the dashboards. You can also insert an image for each Markdown chart to quickly distinguish between dashboards. You can use Markdown charts to describe the parameters of charts. Preview
