kendoChart _toModelCoordinates(x,y) method is missing in the kendo ui v2017.2.504.

We have used this method in the older kendo version v2015.3.1111

_toModelCoordinates:function(t,n){var i=this.element,r=i.offset(),o=parseInt(i.css("paddingLeft"),10),a=parseInt(i.css("paddingTop"),10),s=e(window);return new Xt(t-r.left-o+s.scrollLeft(),n-r.top-a+s.scrollTop())}

Please let us know what is the equivalent alternative method for it in the latest kendo-ui version v2017.2.504 as soon as possible

 

Thanks,

Mahesh

Hello Mahesh,

The method has been moved to an internal instance:
chart._instance._toModelCoordinates
Note however that methods starting with underscore are considered internal and are not recommended to be used because they can be changed. All the method does is subtract the offset so I would suggest to use the approach from the snippet below instead of the internal method:
function surfaceCoordinates(element, x, y) {   
    var offset = element.offset();
 
    return {
        x: x - offset.left,
        y: y - offset.top
    };
}


Regards,
Daniel
