chartjs show dot point on hover over line chart

I am using Chartjs v.1.0.2 and trying to set a point dot only to appear on hover over chart. After it it should be removed. I have managed to show it, by changing the object value, but it is not fluid motion and it doesn’t show point always. This also doesn’t hide it on hover out.
How can it be fluid and hide when mouse is not over?

window.onload = function(){

        var ctx = $("#chart1").get(0).getContext("2d");
                var chart1 = new Chart(ctx).Line(data1, options);

                $("#chart1").hover(function(e) {
                    var activeBars = chart1.getPointsAtEvent(e); 
                    activeBars[0].display = true;
//                    console.log(activeBars[0]);


    var data1 = {
            labels: ["January", "February", "March", "April", "May", "June", "July"],
            datasets: [
                    label: "My First dataset",
                    fillColor: "rgba(95,186,88,0.7)",
                    strokeColor: "rgba(95,186,88,1)",
                    pointColor: "rgba(95,186,88,1)",
                    pointStrokeColor: "#fff",
                    pointHighlightFill: "#fff",
                    pointHighlightStroke: "rgba(220,220,220,1)",
                    data: [65, 59, 80, 81, 56, 55, 40]

var options = {
    responsive: true,
    bezierCurve : false,
    scaleShowLabels: false,
    scaleFontSize: 0,
    pointDot : false,
    scaleBeginAtZero: true,
    scaleShowHorizontalLines: false,
    scaleShowVerticalLines: true,
    scaleGridLineColor : "rgba(232,232,232)",
    showTooltips: true,

    customTooltips: function (tooltip) {
        var tooltipEl = $('#chartjs-tooltip');

        if (!tooltip) {
                opacity: 0

        tooltipEl.removeClass('above below');

        // split out the label and value and make your own tooltip here
        var parts = tooltip.text.split(":");
        var innerHtml = '<span>' + parts[0].trim() + '</span> : <span><b>' + parts[1].trim() + '</b></span>';

            opacity: 1,
            left: tooltip.chart.canvas.offsetLeft + tooltip.x + 'px',
            top: tooltip.chart.canvas.offsetTop + tooltip.y + 'px',
            fontFamily: tooltip.fontFamily,
            fontSize: tooltip.fontSize,
            fontStyle: tooltip.fontStyle,

    I appreciate you taking the time and effort to put this article together.

    I once again find myself spending a significant amount of time both reading and

    find this matter to be actually something which I think I would never understand.
    It seems too complicated and extremely broad for me.
