How it works...

The analytics charts enable you to create intuitive and interactive visualizations of your data. The visualizations are based on data that exists in the Log Analytics repository and queries that filter and shape the data. The chart views then make use of the query results to intuitively present the data. By default, query results are displayed in a table. You can embed the visualization within your query expression itself, and guide the visualization behavior of a query by using the render tabular operator.

This operator takes the filtered query table data as inputs and renders the result in a graphical output. It takes a specified visualization type as an argument. For instance, to render query results in a ladder chart, use the following query:

| render ladderchart

This operator will always begin with the pipeline character, indicating that it is taking query results as input.

If your query result set volume is significant, you can limit the volume that you display by using such tabular operators as top, summarize, and where. Also, note that the render operator will only display positive values.
