Plots did not contain data points (or atleast the live plot did not autoscale)
Tried with num=None and num=5 (with new plot for both), and got the same result.

live_plot_not_working_count_num_is_none
liveplot_not_work_for_count

relative_scan and scan worked after these did not.

Update. Data is not sent to the plot. See image attached. This plan is running the FCCD at 10Hz so that explains why there are missing points from bluesky.

In this case, all 192 data points were saved in the database and just dropped from bluesky.

Thanks for the thorough report. Not sure what this means yet. Thinking.

Ah, the figure title suggests that something isn't right: see how it says "[...] vs e i m t"? That's the word 'time' split up by letter and sorted alphabetically. We caught this bug at ESM and fixed it in time for bluesky v0.10.0. You are still running a slightly out-of-date pre-release version of bluesky, which I intended to resolve on Monday.

You can fix this by doing:

source activate dev
pip install --upgrade bluesky

Note: I'm relying on my memory that the name of the conda environment we used for testing the bluesky is named dev. Check that by running

echo $BS_ENV

All of the above should be run in bash (i.e., the Terminal), not inside IPython/bsui.

Also count() generates a new plot for every scan plan. This isn't ideal because we could have a lot of plots open. Was this the intent?

Clarification, scan() and relative_scan() plot in the same window if the same set of motors and dets are used.

Is this still true after updating bluesky?

That looks like the old NSLS-II proxy issue.

Did this resolve the secondary issue of getting a new figure every time you count?

Will someone be able to upgrade us today? We don't have users now, but will on Tuesday.
