Each row within the legend consists of a label (Y-Scale label or Profile label). If the mouse moves over the Y-Scale label, the event will pass along the scale's index via its YScaleLabel parameter. If the mouse moves over the Profile label, the event will pass along the profile's index via its Profile parameter.
The parameters passed along with the event are described below
|Button||Indicates which mouse button was pressed. 1=Left button; 2=Right button; and 4=Middle button.|
|Profile||A value greater than 0 indicates the Profile's index.|
|YScaleLabel||A value greater than 0 indicates the Y-Scale's index.|
