Dojo Graph Tooltip Arrow Appears Incorrectly

For some reason, the arrow on the tooltip for each graph point appears below the actual label(see image). I have tried doing everything to move it and can not figure out why this is happening. The tooltip is generated automatically by dojo's chart library. It appears fine in the demos.

Does anybody have an idea why? Image of the Broken Tooltip

EDIT: I am using Dojo 1.7.2. The code is question is this.linePlotName is part of the object that the method below resides in.

var anim = new dojox.charting.action2d.Tooltip(newLineChart, this.linePlotName);

Solution

I had the same issue after I upgraded my Dojo from 1.6 to 1.7.2, but this issue was actually a bug and it is fixed now in 1.7.3: http://bugs.dojotoolkit.org/ticket/15016 Upgrade and it should be fine.
