No data shown for some topics in 'Topics Over Time' visualization

[cojoco]

First, I select the 'State of the Union' dataset by clicking 'Datasets' then 'Explore!' on 'LDA with 100 topics'. Then I click 'Visualizations', select 'Topics Over Time', change the metadata to either 'Year' or 'Title', and then begin clicking topics (I tested from 0 to 10). Some topics show data in the graph, while others do not.

This is done with a fresh install of the Topical Guide from https://github.com/cojoco/topicalguide/tree/dev. I tested it with and without 'django-extensions' in the settings.py file, and there was no difference, so it's not that.

Have you been able to verify if the server is returning data? This could be either the data is wrong or the UI is breaking when trying to display the data.

I have not been able to verify whether the server is returning data, no. I have found that this only occurs in the dev branch. The master branch shows what I believe to be the correct data for every topic.

Are you familiar with the various browser dev tools? You can usually access them by right-clicking on something in a web page and selecting "inspect element". Across the browsers I think they all have a network tab, or something to that effect. From that tab you can see every network request a page makes, including the ones that fetch data for the various charts. You can also see the responses from those requests.

If you already are familiar with the tools, please disregard all the parts about how to open them. :)

I checked this, there appears to be one XHR whenever I first click "Topics Over Time", but there are none after that (for example, when switching between topics or using different metadata). This appears to be true of the 2D plot as well, though the 2D plot works just fine.
