Navigator not displaying data

[mwcraig]

Apologies if this isn't the correct place to report this, but I'm using GalaxyZoo/Navigator for a course this semester and I'm not seeing any data when I try to graph, and no bar charts next to each galaxy in the list of my galaxies.

Screenshot below, let me know what other information you would need to help track the problem down.

Thanks for reporting this, @mwcraig.

I know we merged a fix for this several months ago, but I don't know if it was actually deployed.

zooniverse/Ubret#50

@parrish, would you be able to check and see if that's the case?

[parrish]

Since the dependency is only tied to the Ubret @ galaxy_zoo branch, there's no way to know what version is supposed to be running. My last deploy probably knocked out the change if it had been deployed.

I've re-deployed with the latest version. Mind checking again?

Still no data being plotted, either from my groups or from the broader
Galaxy Zoo database.

I don't see any error messages being thrown in the console; it just returns
0 galaxies found.

I had a little look into this, I would like to help further, but am missing a couple of things:

1. @willettk could you add steps to reproduce for the "svg not defined" error you mentioned? Maybe invite me to your group ("alexbfree") where you see it?
2. Does anyone know how to build the navigator locally? It seems that you need to run build.rb to generate the navigator.js file, but I am not sure how to do do this without deploying it at the same time. Maybe @parrish you know how to do this?

Thanks, @alexbfree.

This is on Mac OS X 10.9.5, Chrome Version 48.0.2564.116 (64-bit).

• Go to http://www.galaxyzoo.org/, then click "Navigator"
• Click "Graph data". I'm currently logged in as a member of a group (UMN Zooites), but I'm not going to try to grab data from that group.
• Select "Scatter graph"
• Plot "redshift" vs "apparent brightness" for "smooth" galaxies using data from "Galaxy Zoo" in a "medium sample of random". This works, although it still throws uncaught ReferenceErrors on svg not being defined.

So that mostly works, but the primary problem seems to be that selecting examples from Galaxy Zoo isn't working for both types of galaxies. It works for "Feature/Disk" (500 galaxies easy), but comes up with zero results for "Smooth" galaxies. Then Navigator complains because it's trying to graph empty data sets.

There should be copious amounts of both smooth and featured galaxies in the current data, so that's weird. @alexbfree, could you see if you can duplicate those results? If so, then we can examine why Navigator isn't finding them.

I think @parrish's last deploy may have fixed some of the issues regarding DECaLS data, but we're still missing something.
