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.

To add a panel with a bar chart:
- Create or open a Dashboard and click on Add Panel > Time Series or Add Panel > Categorical.

- Modify the chart as desired.
- Click the Add to Dashboard button on the top right of the window to add the panel to your dashboard.
