Bar charts are useful for visually comparing the number of events that have occurred, such as the type of error that occurs the most in your system. To create a Bar chart, use a search query that provides at least a few data points in the Aggregates tab.
The number of data points on a dashboard panel are limited to 1,000, and therefore only 1,000 data points are shown on a chart panel in dashboards.
For example, you could use the following query to create a simple Bar chart:
(error OR fail*) AND exception | count by _sourceCategory | sort by _count
which would produce results such as:
To create a Bar Chart:**
Run a query.
In the Aggregates tab, choose the Bar Chart icon to display the search results.
The data in the Aggregates tab is represented as a bar chart.
