- You can move the view around programmatically using the .moveTo(options) function. The options supplied to this function can
- also be (partially) supplied to the .zoomExtent() and .focusOnNode() methods. These are explained in the docs.
- <br /><br/>
- The buttons below take the fields from the table when they can. For instance, the "Animate with default settings." takes the position, scale and offset while using
- the default animation values for duration and easing function. The focusOnNode takes everything except the position and the zoomExtent takes only the duration and easing function.
- <br/><br/>
- Here you can see a full description of the options you can supply to moveTo:
- </div>
- <pre>
- var moveToOptions = {
- position: {x:x, y:x}, // position to animate to (Numbers)
- scale: 1.0, // scale to animate to (Number)
- offset: {x:x, y:y}, // offset from the center in DOM pixels (Numbers)
- animation: { // animation object, can also be Boolean
- duration: 1000, // animation duration in milliseconds (Number)
- easingFunction: "easeInOutQuad" // Animation easing function, available are:
- } // linear, easeInQuad, easeOutQuad, easeInOutQuad,
- } // easeInCubic, easeOutCubic, easeInOutCubic,
- // easeInQuart, easeOutQuart, easeInOutQuart,
- // easeInQuint, easeOutQuint, easeInOutQuint
