Kendo图表-如何在不重绘图表的情况下更改工具提示的可见性

Question

I'm using the setOptions method to dynamically show or hide the tooltip. However, every time this changes the entire chart redraws.

Is there a way to use setOptions or another method to set the tooltip visibility without redrawing the chart? I would accept a way to just prevent the re-draw animation.

var chart = $("#chart").data("kendoChart"); chart.setOptions({ tooltip: { visible: false } } );

UPDATE: Thanks to ezanker's answer below, I used the followed to prevent the chart from redrawing every time I updated the tooltip visibility.

$("#chart").kendoChart({
    render: onRender
)}

function onRender(e) {
    var chart = $("#chart").data("kendoChart");
    if (chart.options.transitions)
    {
        setTimeout(function () { //gives chart time to draw initially
            chart.setOptions({ transitions: false });
        }, 1000);
    }
}

If you have a better way to do set transitions to false let me know.

Thank you for your help!

You can turn off the animations

API: http://docs.telerik.com/kendo-ui/api/javascript/dataviz/ui/chart#configuration-transitions

$("#chart").kendoChart({
    transitions: false
});

If you want the initial transition. You could turn it off in the render event so it will only animate the first time.
