Hi Team,

I have installed one of your free plugin named "Artezio Burndown Chart" for JIRA.

However, I am facing issues with no data loaded on configuration.

Could you please assist on this request.

Steps:

I have installed the plugin

Added the gadget in one of the test dashboard

Entered the information required by the gadget

clicked on save

However no results were loaded on the gadget with gadget stays blank.

Here are the logs for you to debug.

Hi, Murthy!

Please provide for Artezio team JIRA and Burndown plugin versions.

And please check: all issues for chart must have estimated time value.

I'm having a similar problem but the stack trace is a little different:

2016-06-20 15:47:54,573 http-nio-8080-exec-73 ERROR nbier 947x99935x1 nalqjr 10.36.64.232 /rest/artbd/1.0/chart/burndown-chart/generate [c.a.jiraboard.rest.ManagedResource] java.lang.NullPointerException
 at com.artezio.jiraboard.util.impl.BurnUpDownManagerImpl.getEstimateByDate(BurnUpDownManagerImpl.java:202)

This seems to point to missing estimated time value like you mentionned. So I added

AND remainingEstimate is not EMPTY and originalEstimate is not empty

at the end of my query but still no luck.
We are using Artezio burndown 1.4 with JIRA Sotware 7.1.2.

PS: It would be awesome if the plugin could treat empty estimates as 0h.Would make our life much easier.
