Mouse-Over Tooltips on a Chartís Axis Titles
This is a feature request for capability to set a mouse-over tooltip on the title next to a vertical or horizontal axis that could show additional information about the axis.
For example, when the end-user does a mouse- over on the ďNumber of HitsĒ vertical axis title on the Column Chart in the Ext GWT Explorer Demo Ė PR5, a customizable SafeHtml tooltip could show additional information about hits (like how the hits are counted or calculated, what might not be included, etc.).
The Flex charts I am replacing have this feature, which is why I am following up with you.
Please let me if this feature will be in the upcoming release.

Yes, it will have tooltip and event support just like axis labels.
