sort generates "Maximum call stack size exceeded" error with big datasets about crossfilter HOT 7 CLOSED

This sounds like an issue involving undefined values. See #3.

You can avoid this by filtering them out, by using the patch in #3, or by replacing them with something else that can be sorted.

I ended up here via Google and want to share the solution to my several hour brain-melt problem, I hope that's alright and not abusing the issue tracker.

If you are getting this error and you are certain that your data file does not have any "bad" lines with missing values or the like, make sure you are actually loading that specific data file...

I tried using a column that did not exist in the tsv data file I had loaded but in the one I thought I was using.

@jasondavies you were right, the problem is with the nan values

from crossfilter.

i have no NaN or undefined values as i queried my databse to exclude all rows where any field contains them, and i still get this error. tried with 200k rows and reduced to 20k, 15k etc it only ever worked with 2k rows. the dataset only had 5 columns. its a great library but im not sure what else to use for visualizing large datasets.

@hariDasu, note that NaN here might not be the constant but any comparison between a number and, say, a string.

I believe the problem arises because it is hard to sort values with the following semantics:

   1<'a'
=> false
   'a'<1
=> false

Therefore your keys must be all numbers or all strings, and your reductions may produce only numbers. (If I understand correctly.)

ahh looks like that was my problem using string values for days rather than encoding them out to digits 0-6 or 1-7. thanks @gordonwoodhull

I am getting the error "Uncaught RangeError: Maximum call stack size exceeded" when I am using a subset of my data. I have created a dashboard with multiple graphs with a very big data set. I then created a smaller one with a subset of the data, but I am not getting this error message. Any ideas? I know there's not a Nan or infinite loop going on.
