Custom Visualizations give you new interactive ways to visualize your data during search and investigation, and to better communicate results in dashboards and reports. After installing this app you’ll find a punchcard visualization as an additional item in the visualization picker in Search and Dashboard. Punchcards can visualize cyclical trends in your data. This visualization shows circles representing a metric aggregated over two dimensions, such as hours of the day and days of the week. Using a punchcard, you can see relative values for a metric where the dimensions intersect.
