[[visualize]] == Visualize You can use the _Visualize_ page to design data visualizations. You can save these visualizations, use them individually, or combine visualizations into a _dashboard_. A visualization can be based on one of the following data source types: * A new interactive search * A saved search * An existing saved visualization Visualizations are based on the {ref}search-aggregations.html[aggregation] feature introduced in Elasticsearch 1.x. [float] [[createvis]] === Creating a New Visualization Click on the *Visualize* image:images/visualize-icon.png[chart icon] tab in the left-hand navigation bar. If you are already creating a visualization, you can click the *New* button in the toolbar. To set up your visualization, follow these steps: [float] [[newvis01]] ==== Step 1: Choose the Visualization Type Choose a visualization type when you start the New Visualization wizard: [horizontal] <>:: Use area charts to visualize the total contribution of several different series. <>:: Use data tables to display the raw data of a composed aggregation. You can display the data table for several other visualizations by clicking at the bottom of the visualization. <>:: Use line charts to compare different series. <>:: Use the Markdown widget to display free-form information or instructions about your dashboard. <>:: Use the metric visualization to display a single number on your dashboard. <>:: Use pie charts to display each source's contribution to a total. <>:: Use tile maps to associate the results of an aggregation with geographic points. <>:: Use vertical bar charts as a general-purpose chart. You can also load a saved visualization that you created earlier. The saved visualization selector includes a text field to filter by visualization name and a link to the Object Editor, accessible through *Settings > Objects*, to manage your saved visualizations. If your new visualization is a Markdown widget, selecting that type takes you to a text entry field where you enter the text to display in the widget. For all other types of visualization, selecting the type takes you to data source selection. [float] [[newvis02]] ==== Step 2: Choose a Data Source You can choose a new or saved search to serve as the data source for your visualization. Searches are associated with an index or a set of indexes. When you select _new search_ on a system with multiple indices configured, select an index pattern from the drop-down to bring up the visualization editor. When you create a visualization from a saved search and save the visualization, the search is tied to the visualization. When you make changes to the search that is linked to the visualization, the visualization updates automatically. [float] [[visualization-editor]] ==== Step 3: The Visualization Editor The visualization editor enables you to configure and edit visualizations. The visualization editor has the following main elements: 1. <> 2. <> 3. <> image:images/VizEditor.jpg[] [float] [[viz-autorefresh]] include::autorefresh.asciidoc[] [float] [[toolbar-panel]] ===== Toolbar The toolbar has a search field for interactive data searches, as well as controls to manage saving and loading visualizations. For visualizations based on saved searches, the search bar is grayed out. To edit the search, replacing the saved search with the edited version, double-click the search field. The toolbar at the right of the search box has buttons for creating new visualizations, saving the current visualization, loading an existing visualization, sharing or embedding the visualization, and refreshing the data for the current visualization. [float] [[aggregation-builder]] ===== Aggregation Builder Use the aggregation builder on the left of the page to configure the {ref}search-aggregations-metrics.html[metric] and {ref}search-aggregations-bucket.html[bucket] aggregations used in your visualization. Buckets are analogous to SQL `GROUP BY` statements. For more information on aggregations, see the main {ref}search-aggregations.html[Elasticsearch aggregations reference]. Bar, line, or area chart visualizations use _metrics_ for the y-axis and _buckets_ are used for the x-axis, segment bar colors, and row/column splits. For pie charts, use the metric for the slice size and the bucket for the number of slices. Choose the metric aggregation for your visualization's Y axis, such as {ref}/search-aggregations-metrics-valuecount-aggregation.html[count], {ref}/search-aggregations-metrics-avg-aggregation.html[average], {ref}/search-aggregations-metrics-sum-aggregation.html[sum], {ref}/search-aggregations-metrics-min-aggregation.html[min], {ref}/search-aggregations-metrics-max-aggregation.html[max], or {ref}/search-aggregations-metrics-cardinality-aggregation.html[cardinality] (unique count). Use bucket aggregations for the visualization's X axis, color slices, and row/column splits. Common bucket aggregations include date histogram, range, terms, filters, and significant terms. You can set the order in which buckets execute. In Elasticsearch, the first aggregation determines the data set for any subsequent aggregations. The following example involves a date bar chart of Web page hits for the top 5 file extensions. To use the same extension across all hits, set this order: 1. *Color:* Terms aggregation of extensions 2. *X-Axis:* Date bar chart of `@timestamp` Elasticsearch collects the records for the top 5 extensions, then creates a date bar chart for each extension. To chart the top 5 extensions for each hour, use the following order: 1. *X-Axis:* Date bar chart of `@timestamp` (with 1 hour interval) 2. *Color:* Terms aggregation of extensions For these requests, Elasticsearch creates a date bar chart from all the records, then groups the top five extensions inside each bucket, which in this example is a one-hour interval. NOTE: Remember, each subsequent bucket slices the data from the previous bucket. To render the visualization on the _preview canvas_, click the *Apply Changes* button at the top right of the Aggregation Builder. You can learn more about aggregation and how altering the order of aggregations affects your visualizations https://www.elastic.co/blog/kibana-aggregation-execution-order-and-you[here].
