The project dashboard allows you to view and compare performance across multiple experiments. In addition to viewing the metrics we have added automatically for you, you can add more visualizations to the dashboard.

Each action is explored in detail in the respective sections below.


When clicking on an experiment from the experiments list, you are redirected to the Single Experiment page.

Manage the experiments list

The Experiments sidebar provides you with a list of all your experiments. This list can be customized through some of the actions available next to the Experiments header:

  1. Filter experiments: Filter down the experiments based on any of the data logged to them.
  2. Sort experiments: Sort the experiments based on any of the data logged to them.
  3. Group experiments: Group experiments based on metadata, Comet will display in the charts the experiments from the last opened grouped.


The experiments displayed in each panel is related to the experiments in the sidebar. You can view more experiments in each panel by increasing the page size to 100 for example. You can also go to the next page to see the next set of experiments.

Please refer to the Manage displayed experiments section for information on how to manage the experiments list.

Perform bulk actions on selected experiments

From the Project Panels page, you can select experiments and perform actions using the bottom action bar. The most commonly used actions include:

  1. Diff: Allows you to compare up to 4 experiments side by side
  2. Archive: Soft-delete the selected experiments
  3. Tag: Add a tag to all the selected experiments, can be useful for filtering

Please refer to the Perform bulk actions on selected experiments section for more information.

Update the dashboard view

The dashboard displays all panels for the specified view. Comet defaults to the "Auto Generated" view which is created by Comet automatically for your project and displays the 12 most common metrics for your project.

You can customize this dashboard by editing the panels, updating dashboard settings or adding your own visualizations to it. You can learn more about all the visualizations Comet has to offer here.


Any changes you make to the Auto-Generated will be saved for your user but will not be accessible to other users. If you would like to share your view, simply you can save it using the Save View button.

Edit the panels

A panel is a built-in or custom Python visualization. Review the available panels in the Visualizations section.

Group panels in sections

You can group panels inside sections.

To create a section, click on the Add section button at the bottom of the Panels dashboard.

Every section has a customizable name that you can update by clicking on the Pencil icon that appears when hovering by the section name.

Additionally, from the three vertical dots icons by the section name, you can:

  • Move the section up or down.
