LinkToGlobal loses visualization on scroll and reverts view to Unix epoch

Open adamconkey opened this issue 3 months ago • 2 comments

Describe the bug

When using the LinkToGlobal feature to link time axes of multiple series plots in the viewer, the plotted data can disappear when you scroll to a location in the timeline where there is no data. Double-clicking to try to re-home the view sends it to timestamp zero and from there it's very to hard to recover any sane interaction.

To Reproduce Steps to reproduce the behavior:

  1. Open rerun viewer with rerun and select the "IMU Signals" example
  2. For each of the two time series plots, change the View properties > Time axis setting to LinkToGlobal
  3. Note timestamp where data is visible (18:46:20)
  4. In one of the plots, click and drag the view with your mouse horizontally to a timestamp nearby where no data is visible in either plot anymore (e.g. to 18:46:10)
  5. Scroll back to timestamp where data is visible (18:46:20). Note data has disappeared!
  6. Double-click one of the plots in an attempt to recover, note the timeline goes to 1970-01-01 (Unix epoch)!

Expected behavior

  1. When LinkToGlobal is active for two plots, and you were to scroll beyond the timestamp where data is plotted such that no data can be seen in the plots, I should be able to scroll back to where the data is plotted and still see the data.
  2. Double-clicking a plot should always re-home the view back to where data is plotted.

Related to https://github.com/rerun-io/rerun/issues/11168, likely the same underlying problem.

With #11621 merged this bug still kind of exists, but acts a bit differently.

To Reproduce Steps to reproduce the behavior:

  1. Open rerun viewer with rerun and select the "IMU Signals" example
  2. For each of the two time series plots, change the View properties > Time axis setting to LinkToGlobal
  3. Note timestamp where data is visible (18:46:20)
  4. In one of the plots, click and drag the view with your mouse horizontally to a timestamp nearby where no data is visible in either plot anymore (e.g. to 18:46:10) ~~5. Scroll back to timestamp where data is visible (18:46:20). Note data has disappeared!~~ Data is still there. ~~6. Double-click one of the plots in an attempt to recover, note the timeline goes to 1970-01-01 (Unix epoch)!~~ (new) double click when no data is visible on either plot anymore, note the timeline goes to 1970-01-01 (Unix epoch)!
