Burn-Down chart is always empty

[cleankod]

It doesn't draw anything...
It does draw the "Spent time" when I turn off the "Remaining estimate" then turn off "Spent time" and turn on "Spent time" again.

Start date from 1970.
I think the problem is caused by the fact that "highcharts" receives incomplete (not valid) data.

[bcmedeiros]

Same problem here... I can only get some chart when uncheck "Remaining estimate".
AlexMcArrow, maybe you're right, but what should be the complete data to highcharts?

[caiiiyua]

Any update for this issue ?
I got the same problem with you guys.

1. Start date from 1970
2. No chart is drew
3. Disable remaining estimate could see some of task draw on the chart.

Same for me, burn down is empty no matter what I do.

[aqwerf]

I found the problem point, and fix it temporarily (assets/javascripts/burndown.js)
After that, burndown chart works well.

After that fix I get this:

Could not copy /opt/redmine/plugins/AgileDwarf/assets/javascripts/burndown.js to /opt/redmine/public/plugin_assets/AgileDwarf/javascripts/burndown.js: Permission denied - /opt/redmine/public/plugin_assets/AgileDwarf/javascripts/burndown.js

And even after I put back changes still the same error.

EDIT: I have changed permissions on that file and now it is OK. But no chart displays at all now.
EDIT 2: Had to restart apache server, my fault.

[geoff-intellipharm]

I added the the above fix by aqwerf and the charts at least display now just with no data on them.. they also start from 1970 so I am assuming that it is still broken somewhere. Does anyone know where it gets the data for this burn down? is it from the due dates set for the tasks?

Date.fromMysql = function(mysql) { if (typeof mysql != 'string') return null; // 2011/11/03 00:00:00 +0800 var t = mysql.split(/[\/ -:]/); // [Y, M, D] return Date.UTC(t[0], t[1] - 1, t[2]); };

After a bit of debugging I noticed that in the function above it returns the of the split var t incorrectly ... some of the dates passed to this function have the full UTC format with T and Z in them (i.e. 2012-11-02T12:04:00Z) perhaps it is this split that is not working correctly and hence passing invalid dates in the data for highcarts?

I don't have time to spend on fiddling with it but perhaps this might give someone some idea

aqwerf's patch worked like a charm!
Apply patch (unfortunately it did'nt work with patch so had to do it manually) and restarted apache.

Thanks :)

[geoff-intellipharm]

^^ can you state which version of redmine this patch worked with?

Thanks!

[baumanno]

Sure, we have Redmine 2.1 running and cloned AgileDwarf from here

[nrchandan]

aqwerf's solution worked for me too! I modified the burndown.js manually and restarted redmine. Using latest redmine 2.2.3.

Now I have to look for solution to the tasks's tab problem. I don't see any tasks in that tab.

[AlexAndrascu]

Please commit this. I can confirm it's working. Thanks

[alfonsonishikawa]

Sadly, the patch does not work with Redmine 1.3.2 :'(
Without the patch works with Redmine 1.3.2, but you must have at least one task with some "Spent Time" and "%Done > 0%". Otherwise, no graph is shown.

[julurigeethanjali]

aqwerf's solution worked for me. But when I turn off "Spent time" Remaining estimates graph is not plotted. All the tasks are having spent time. Please post a solution for this.. Thanks in advance

[acosonic]

I actually fixed it for newest version (fork) from greenius by completly removing sprints_tasks....
