how to display "year" labels correctly in d3.parcoords.js

[Frankie Zhou]

Hi all,
My data has a column of "year", which is different year values, such as 1980, 1999, 2016. However, when I use d3.parcoords.js visualize the data, the labels on "year" axis display as scientific number format, i.e. "1980"-->"1,980", "2016"-->"2,016". May I know how to customize the labels to display as we expect? Thanks!

Hello,

Parsing the years into Date objects might do the trick, but I'm not sure how d3.parcoords.js would handle that exactly:

d.year = new Date(d.year, 0)

Another solution might be to override the number format for the axis with the identity function:

axis.tickFormat(function (d){ return d; });

If you can share your code on bl.ocks.org (maybe using Blockbuilder), folks can have an easy time to take a look and try to help make it work. Your question is difficult to answer in a precise way without seeing the code.

Best Regards,
