Custom charts can be created in the fields sidebar?

Creating custom charts directly in the fields sidebar is not a feature available in Splunk. The fields sidebar is primarily designed to display extracted fields and provide insights into the data being visualized in a panel or dashboard. It allows users to interact with the fields, but it does not facilitate the actual creation or customization of charts.

Custom charts are typically created through visualization settings in the search interface, where users can define the data they want to visualize and choose the appropriate chart type, along with various settings to customize the appearance and behavior of the chart. This approach is more suited for managing visualizations rather than relying on the sidebar for chart creation.
