I am plotting area chart using amcharts, the x-axis data date values range from 08/01/2014 to 08/30/2014. But the graph displaying the x-axis values from 07/31/2014 onwards. This issue is found only in latest version of windows Firefox and chrome. Attaching the screen shot of the graph plotted and the dataProvider values below.

dataProvider = [{ "value": 0, "date": "2014-08-01" }, { "value": 17 "date": "2014-08-02" }, { "value": 24 "date": "2014-08-03" }, { "value": 26 "date": "2014-08-04" }, .... ] Plotted chart

How could I solve this? Any help would be appreciated. Thanks in advance.

I was unable to reproduce this. Could we (amcharts) get full source code. It would be best if you could address directly to our support. – zeroin
@zeroin Please see the updated fiddle. The categoryBalloon value also shows 07/31/2014. – Shinoj
@zeroin This issue is able to reproduce in windows chrome(v 37.0.2062.120) and firefox version (v32) – Shinoj
Strange, I can't reproduce this in any browser. Try setting dataDateFormat:"YYYY-MM-DD" on the chart instance ( you must set dataDateFormat or use Date Objects instead) – zeroin
Thanks zeroin. Fixed the issue by setting dataDateFormat on chart instance. – Shinoj

I updated your fiddle here:

The issue is the TIMEZONE. Amcharts appears to be taking the given time as UTC and converting back to your local time.

In the fiddle I modified the first few data points to 

2014-08-01T10:00:01

next to 8AM next to 7AM (I am in California) and voila! date appears as expected in the balloons.
