Adding a visualization to a dashboard

  1. Click Visualize in the side navigation.

  2. Click Create new visualization or the + button.

  3. Choose the visualization type. For more information, see types of visualization.

  4. Specify a search query to retrieve the data for your visualization:

    • To enter new search criteria, select the index pattern for the indices that contain the data you want to visualize. This opens the visualization builder with a wildcard query that matches all the documents in the selected indices.

    • To build a visualization from a saved search, click the name of the saved search you want to use. This opens the visualization builder and loads the selected query.

      When you build a visualization from a saved search, any subsequent modifications to the saved search are automatically reflected in the visualization. To switch off automatic updates, you can disconnect a visualization from the saved search.
  5. In the visualization builder, choose the aggregation for the visualization’s y-axis. For more information, see Y-axis aggregations.

  6. For the visualizations x-axis, select a bucket aggregation. For more information, see X-axis aggregations.

For example, if you are indexing Apache server logs, you could build a horizontal bar chart that shows the distribution of incoming requests by geographic location by specifying a term’s aggregation on the geo.src field:

The y-axis shows the number of requests received from each country, and the countries are displayed across the x-axis.

Bar, line, or area chart visualizations use metrics for the y-axis and buckets for the x-axis. Buckets are analogous to SQL GROUP BY statements. Pie charts, use the metric for the slice size and the bucket for the number of slices.

You can further break down the data by specifying sub aggregations. The first aggregation determines the data set for any subsequent aggregations. Sub aggregations are applied in order—you can drag the aggregations to change the order in which they are applied.

For example, you could add a terms sub aggregation on the geo.dest field to a vertical bar chart to see the locations those requests were targeting.
