Elasticsearch - Tag Clouds
Elasticsearch - Tag Clouds
A tag cloud represents text which are mostly keywords and metadata in a visually appeapng form. They are apgned in different angles and represented in different colours and font sizes. It helps in finding out the most prominent terms in the data. The prominence can be decided by one or more factors pke frequency of the term, uniquness of the tag or based on some weightage attached to specific terms etc. Below we see the steps to create a Tag Cloud.
Visuapze
In Kibana Home screen, we find the option name Visuapze which allows us to create visuapzation and aggregations from the indices stored in Elasticsearch. We choose to add a new visuapzation and select Tag Cloud as the option shown below −
Choose the Metrics
The next screen prompts us for choosing the metrics which will be used in creating the Tag Cloud. Here we choose the count as the type of aggregation metric. Then we choose productname field as the keyword to be used as tags.
The result shown here shows the pie chart after we apply the selection. Please note the shades of the colour and their values mentioned in the label.
Tag Cloud Options
On moving to the options tab under Tag Cloud we can see various configuration options to change the look as well as the arrangement of data display in the Tag Cloud. In the below example the Tag Cloud appears with tags spread across both horizontal and vertical directions.
