title: View Operations

|
Robotics data has many sensors and many columns.
|
|
In order to more narrowly specify relevant content for further dataframe operations you first generate a view.
|
|
This view can filter on episode, time, column name etc.
|
|
This example shows specific instances highlighting these capabilities.
|
|
|
|
The dependencies in this example are contained in `rerun-sdk[all]`.
|
|
|
|
## Setup
|
|
|
|
Simplified setup.
|
|
Perform imports and launch local server for demonstration.
|
|
Extract an initial view `observations` that we later refine before generating a dataframe.

## Filtering on episode and time
|
|
|
|
Limit the scope of the view so that only a subset of data will ever be considered client side.
|
|
Pick a specific episode by id, and a time range.

## Querying static data
|
|
|
|
So far we've been selecting `real_time` as the index. However, some data might not change in time (e.g. static transformations)
|
|
and thus isn't aligned with a time index. We specify this static timeline with `None`.
