Inconsistent YAxes across instructors #60

Closed samjett247 closed 4 years ago

Please make your rating axis go all the way to zero in the Y dimension. Otherwise it could be said that you are trying to magnify differences in the data as the difference between 4.1, 4.2 and 3.5 looks like a massive drop.....

I'm seeing some courses (I guess with no reviews) where the mean is 0.

samjett247 commented 4 years ago

That doesn't necessarily imply individual reviews are 0 - could be their alternative to a null value. I can look into individual values tonight, I think the best way is to check the pdfs from the source.

zachschuermann commented 4 years ago

Yea I agree. But since we aggregated with 0's there are 0, 0.5 etc.

samjett247 commented 4 years ago

Based on this, I think YAxes should go 1-5. Going to implement this in FrontendUpdates branch.

Okay, I played around with changing YAxes on range[1-5] and it just obscures any meaning you can get from the graph. Would be like if you plotted some parameter that varied from 80-90% on a 0-100% axis. It just doesnt convey meaning. I still made some changes in new branch; Will do PR in a second.

Not making this change for now.
