When using Date object as X data label differs with one month

  I’ve just recently started to play around with canvasjs, so I might have missed something, but I came across an oddity which may be a bug.

  See: https://jsfiddle.net/e2o36mf0/

  If you zoom into the chart (preferrably at the very start) and compare the Y-values in the script and the chart you’ll notice that the x-axis is exactly one month ahead in the chart compared to the datapoint.
  I’m sorry for posting so many datapoints, I just wanted the example to contain the data I’m working with to make the test more realistic.
  I’d appreciate if you would let me know if this is a bug or something else.
  Thanks also for a very interesting piece of software.
  Very best

  Hi,

  The JSFiddle that you have provided is blank. Looks like u forgot to save the fiddle. Can you please updated the same so that we can have a look.

  Oops! Sorry.
  I had to fork out your original fiddle again. Here’s a link to the new one:

  I’ve used a handful of points this time.

  Well, I think I may have found a solution

  For some reason I output the dates in descending order in the first example. When changing the sort order to ascending everything is fine!

  I have same problem,

  I’m using canvasjs charts on lots of my sites, but just noticed today that all of them is one month ahead somehow,

  I just checked the data the chart was getting, and the time is correct.

      [3894] => Array
          (
              [totalweight] => 13842951
              [time] => 2015, 05, 26, 15, 00
          )

  But the chart shows 2015, 06, 26, 15, 00

  I tried sorting it as per brunberg posts, but didn’t work.

  Any suggestions?

  Hi,

  This is not a bug. JavaScript month index starts from 0. Hence month 0 (January) becomes 1 displaying. Please refer to this thread.
