Zoom Interactor
A zoom interactor has the following basic characteristics:
Class
Registered name
“ChartZoom”
Key or Button
- Left mouse button to zoom in
- Shift + Left mouse button to zoom out
Action
Lets the user trigger a zoom-in or a zoom-out
command by dragging a box within the data
display area of a chart. This box indicates the
area to be zoomed in or zoomed out.
The mouse button used to perform the zoom-in and zoom-out operations is the left mouse button by default. However, this button can be changed by passing another button as a parameter to the constructor of the zoom interactor.
Each zoom-in/zoom-out operation can be broken down into several steps to render a smooth transition between the original and the final visual state of the displayed data. When a zoom interactor instance is created, the default number of steps is set to 0. You can specify the number of steps by means of the setZoomSteps method.
