OpenAPS Plugin, predBGs causing display issue

[boc-the-git]

Having recently got my loop running via OpenAPS I'm noticing a negative impact on NS. When predBGs is populated (specifically within the 'enacted' attribute), it is screwing up the alignment of everything on NS.

I'm a relatively new user, so can't confirm if this is a long time issue or not, though I couldn't find any relevant issue.

This is an example of the devicestatus record causing the issue, I've confirmed with 5+ different records that the presence of predBGs is the trigger for the issue:

This is what it looks like with the predBGs attribute in place:

This is when removing the predBGs attribute from the record in the DB:

Note I was able to work around the issue a bit by setting the SHOW_FORECAST variable to null (instead of openaps), but that obviously defeats the purpose of the data, and makes it look fairly similar to manually removing the predBGs

@scottleibrand can you explain this?

[scottleibrand]

This graph is completely missing BG information. Nightscout rarely displays correctly without BGs: no one designed it to.

[scottleibrand]

I’d jump into Gitter if you need help getting your CGM info uploaded to NS. There are lots of different methods.

[PieterGit]

@scottleibrand Thanks (I should have better looked at the screenshots). @BOC14 please make sure your cgm uploading works. Please ask help if you need it, e.g. at https://gitter.im/nightscout/intend-to-bolus
Closing this issue, because it looks like a problem with the uploader. Feel free to reopen if it's needed and you have your cgm upload in order.
