🧮 Write your own source-controlled scripts for manipulating data​

We've added a new type of Foxglove extension that allows you to manipulate data and create new topics on the fly for visualization.

Semantically, these new topic message converters are similar to user scripts, but they are available across layouts and can be used to deploy "user-scripts" organization-wide. Like other extensions, they support code reuse, development in your own IDE, and use of third-party modules.

What used to be called a message converter is now called a schema message converter (schema converter for short). This new type of extension is called a topic message converter (topic converter).

How are the new Topic Message Converters different?​

Topic converters are more flexible than schema converters. Where schema converters assume a 1:1 relationship between proprietary schemas and well-known schemas, topic converters do not have this restriction. They can produce new topics from one or more input topics. These new topics can output custom types or other well-known schemas.

Topic converters support:

• One or more input topics
• Maintaining state (you can aggregate signal data from previous input messages to produce new output—allowing you to make filters or perform arbitrary math on signal data)
• Extract individual fields from a message to separate top-level topics
• View output of new topics in plots and State Transition panels (or any panels that use range subscriptions)

When should Schema Message Converters be used?​

We recommend using these when there is a 1:1 relationship between some internal schema and a well-known schema. Common examples:

• Converting proprietary GPS messages to foxglove.LocationFix for display in the Map panel
• Converting internal Log messages to foxglove.Log for the Log panel
• Converting business logic to foxglove.SceneUpdate for display in the 3D panel

📒 Multi-file upload​

You can now select multiple files and upload them simultaneously from the app.

⛰️ Support for Grid Maps in 3D​

We've added support for visualizing grid_map_msgs/GridMap messages in Foxglove. Grid Maps can be used to represent and visualize 2.5D height map information as well as other layers in the 3D panel. Common data layers stored in GridMap include elevation, variance, color, friction coefficient, foothold quality, surface normal, traversability, and more.

For visualizing surfaces in the 3D panel, Foxglove currently supports two interpolation methods between points:

• Nearest neighbour: Creates cube volumes at the nearest grid point containing the elevation data (faster, less accurate representation of the surface).
• Linear: The value of any point (x, y) on the surface is estimated using bilinear interpolation or the four neighboring grid points (slower, more accurate representation of the surface).

📐 Inspect and measure points in the Plot panel​

We've added inspect and measurement tools to the Plot panel. With the tool enabled, you can click on any point to highlight its x and y-values. Select a second point to view the x and y-delta between the points. Additionally, when viewing a path-based XY plot (as opposed to a time-series plot), the tool will also display the Euclidean distance between the two points.

🔬 Easier zooming in the Plot panel​

We've updated how you zoom in the Plot panel for a faster and more intuitive experience. When scrolling to zoom, hold Shift to zoom in y-axis and Alt/Option to zoom in the x-axis modifiers. You can also scroll either axis by hovering over the respective axis area for the plot.

📜 Quickly scroll through State Transitions​

If your State Transitions panel contains a large number of rows, you can now use Shift + Scroll to quickly scroll through them.

New & Improved

🚢 Performant API for visualizing data across a time range​

The subscribeMessageRange extension API is now generally available. Using this API, Foxglove can load data in small chunks and cache only a subset of serialized data. By doing this, heap memory usage is reduced while still allowing fast re-reads. As a result, panels can display larger datasets without exhausting memory resources.

The subscribeMessageRange API should be used instead of preload: true and context.watch("allFrames") in order to load data across a data source. These previous APIs are now deprecated.

The reference documentation for the extension API is also now available in the core Foxglove documentation.

⏮️ Quick navigation to recent layouts​

The layout menu now shows a list of recently used layouts at the top for quick navigation.

⏲️ Efficient loading of time-range data​

In order to improve app stability and memory efficiency, we’ve completely overhauled how data is handled for panels that request all messages for a topic across the entire time range (for example, Plots, State transitions, and Maps showing location history).

Instead of indefinitely caching all deserialized messages, Foxglove now loads data in small chunks and caches only a sub-set of serialized data. This greatly reduces heap memory usage while still allowing fast re-reads. As a result, panels can display larger datasets without exhausting memory resources.

No user action is required—just enjoy smoother performance when working with range-loaded data. Learn more about range loading in the extension API docs.

🔓 Custom OIDC configurations​

Whether you use Okta, Microsoft Entra, Rippling, or another Open ID Connect (OIDC) compliant solution, you can now federate with Foxglove and centrally manage user access—right from your existing identity management system.

Read our docs to learn more about federating with your OIDC provider. This feature requires an Enterprise plan.

🧊 3D Panel enhancements​

We've made multiple improvements to the 3D panel to make it easier to navigate and inspect objects in your scene. The full list of 3D panel shortcuts is available in the 3D panel docs.

Recenter 3D panel​

The 3D panel now has a button to reset the camera position to the origin of the display frame. This can also be accessed using the 1 keyboard shortcut.

3D panel crosshairs​

The 3D panel now shows crosshairs while moving the camera to indicate the center of rotation/zoom. The crosshairs display when the camera is moving and disappear when the camera is still.

Vertical panning​

You can now pan the 3D panel in the camera plane by holding option/alt and dragging the mouse. By default, panning moves the camera parallel to the z=0 plane.

Object inspector short-cut​

Quickly enable and disable a 3D panel's object inspector using the a keyboard shortcut: i.

Check out the recording of our recent live demo to learn how the object inspector can be used with global variables to create plots and user scripts that react and update based on your interactions.

📈 Plot panel enhancements​

In addition to the 3D panel, we're also busy making the Plot panel more intuitive and powerful.

Independent x-axis values for plot series​

You can now set the x-axis values independently for each series in path-based (XY) plots. This means you can plot multiple series on the same plot, for example [x1, y1] and [x2, y2] where each of x1, y1, x2, and y2 are separate message fields.

Axis labels for Plots and State Transitions​

You can now set custom axis labels for Plots and State Transitions panels to make your State Transitions and Plots easier to understand.
