When creating a stockchart (with the navigator) setting the frequency to annual. If the dataset starts on 1/1/1970 the chart doesn't display anything. If you show a dataset starting before 1970 (which can include a value on 1/1/1970) the chart displays fine.
I've got a temporarily fix - if the year is 1970 then I set the date to 2/1/1970 so the chart works as it should.

Kendo version: KendoUI-2014.2.1008 (don't judge, IE8)

Hi,

I tried reproducing the issue in this dojo, but without great luck. What am I missing?

Using IE8 shouldn't be a problem. Still, you can try running this against the latest version to check if it's something we fixed.

I think you've replicated the problem perfectly!

When running the script as you've created it, I get a blank chart (as per the first screenshot). When I change the line Date: new Date(1970, 0, 1 + i) to Date: new Date(1970, 0, 2 + i)  (i.e. changing it from starting on 1/1/1970 to starting on 2/1/1970) the chart displays as per my second screenshot.

I've tried this in Chrome 50.0.2661, Firefox 45.0.2 and IE11 and I see the same behaviour everywhere.

Hi,

Then it surely must be the time zone. I was running the demo in EEST (Europe/Sofia). Switching to GMT "solved" it.

We'll investigate and try to provide a fix for the service releases following our R2 release next week.

I've updated our Telerik points as a token of gratitude for your involvement.
