Track when the discrete values of topic message paths, specified using message path syntax, change.
When playing back a pre-recorded data source (e.g. a local or remote
.bag file), this panel will preload the data belonging to the specified topic message paths for the whole playback timeline.
Current playback time will be indicated by a vertical gray bar.
Paths can point to any primitive value (numbers, booleans, enums, etc.), but will be most useful for "enums".
Note: Constants included in your ROS message definition will be displayed as a label for each "enum" plot. Limit enums to one per message definition, as Studio will not know which constant name to use in the event of multiple matches.
Scroll to zoom, and drag to pan. Double-click to reset the view.
Hover over any point on a chart to see its details in a tooltip. You'll see a vertical yellow bar appear, as well as a corresponding yellow marker on the playback timeline.
Click to seek playback to the yellow marker on the timeline.
