The ActionListener then calls different classes to manipulate graphs depending on the action. This worked while the class had few ActionListeners; however, now the class is becoming unmanageable.

I'm working on a control for one of our apps. The control shows the currently focused day as a gird, the X-axis being time of day. The Y axis doesn't have a scale as such, rather it will separate out the items to be displayed. The overall look of the control will be quite similar to a gantt chart, showing the times of day of various t...
