Zoom In Zoom out feature

[sherlholmes]

Zoom in zoom out feature using mouse wheel is not working on Internet explorer.

Which version of IE? What kind of graphics are you using (SVG or CSS)?

[sherlholmes]

In IE9, I am Using SVG graphics.
Is there any way to have simple slider for zooming?

Has there been an update to this?

IE used to be special but like with many other things MS gave up on being special. So to make zooming with the mouswheel work in IE11 the updateScrollEvents function in vivagraph needs to be modified just a little bit. Basically remove the 'special' treatment for IE and use the 'mousewheel' event for all browsers.

REPLACE BOLD TEXT WITH 'mousewheel' or just get rid of the if/else statement all together.
Hope this helps.

if (browserInfo.browser === 'webkit') {
element.addEventListener('mousewheel', handleMouseWheel, false); // Chrome/Safari
} else {
element.addEventListener('DOMMouseScroll', handleMouseWheel, false); // Others
}
