类名称：ZoomControl

ZoomControl介绍

[英]Zooms the display, changing the scale of the viewable region. By default, zooming is achieved by pressing the right mouse button on the background of the visualization and dragging the mouse up or down. Moving the mouse up zooms out the display around the spot the mouse was originally pressed. Moving the mouse down similarly zooms in the display, making items larger.
[中]缩放显示，更改可视区域的比例。默认情况下，通过在可视化背景上按鼠标右键并上下拖动鼠标来实现缩放。向上移动鼠标将缩小最初按下鼠标的位置周围的显示。向下移动鼠标同样会放大显示，使项目变大。
