c3: Failing to parse dates

When I use the timeseries type, I keep getting the “Failed to parse x to Date object” error. On dates like ‘2014-08-12T00:00:00.000Z’, which when I try to make with new Date in the console, work just fine. Any idea why this is happening?

Just ran into this myself. The format suggested earlier does not actually match the date format requested in the original post.

Got lucky and found a helpful hint here in the D3 wiki about ISO formatting.

This worked for me:

use xFormat prop as recommended
use this format value: %Y-%m-%dT%H:%M:%S.%LZ
Here’s a JSFiddle for proof

Hi, please try data.xFormat if you load datetime string:

data: {
  ..
  xFormat: '%Y-%m-%d %H:%M:%S'
  ..
}

UPDATE: I updated the reference in c3js.org. Sorry for the confusion and poor document.
