Unexplainable Uncaught TypeError: undefined is not a function

javascript,undefined

I think that's due to the fact that, in the function loadExamsyou have a statement var avg = avgArr[i].sAvg / avgArr[i].sCfu; which will shadow your function definition (since it's in a more inner scope). Rename to variable to something else (or the function). As a best practice, define your variables...

Why does my .data function work in pieChart but not in lineChart in dc.js?

javascript,undefined,dc.js

Sorry, but you aren't going to be able to use .data() with bar or line charts with a reasonable amount of effort, because dc.js uses .data() internally and in this case you would have to call d3.stack yourself in order to create the data it is expecting. Instead, I suggest...

How can this be undefined in the constructor of an Angular config class?
