What should you do if your custom chart is not appearing in the chart library?

When a custom chart is not appearing in the chart library, enabling the "show custom" button is the appropriate action to take. This feature typically controls the visibility of custom charts within the library, and by enabling it, you allow those charts to be displayed alongside any standard charts already provided.

This option focuses specifically on making sure that the user interface is configured to display all available resources, including custom content. If this option is not checked, even if the chart exists, it will not be visible to the user.

Other potential actions, like refreshing the page, recreating the chart, or adjusting user permissions, may not address the primary issue, which is the visibility of the chart rather than its existence or the permissions surrounding it. Thus, enabling the show custom button effectively resolves the problem of the custom chart not appearing in the chart library.
