    I need the same hover effect on Canvas js bar graph.

    https://jsfiddle.net/alidingling/30763kr7/

    Would it be possible to hide the bars and shows bar only on hover.

    -> initially bars will be hidden
    -> on hover bars, it will display the hovered bar only.

    Would like to show the clear dots.

<html>
<head>
<script type="text/javascript">
window.onload = function () {
	var chart = new CanvasJS.Chart("chartContainer",
	{
		title: {
			text: "Setting lineDashType for axisX"
		},
		axisX: {		       
			lineDashType: "dot",
			lineThickness: 2
		},
		axisY: {
			gridThickness: 0
		},
		data: [
		{
			type: "line",
			dataPoints: [
				{ x: 10, y: 4 },
				{ x: 20, y: 3 },

    @as3script,

    I need the same hover effect on Canvas js bar graph.

    You can achieve this either using stripLines as shown in this JSFiddle or crosshair as shown in this JSFiddle.

    -> initially bars will be hidden
    -> on hover bars, it will display the hovered bar only.

    Please take a look at this JSFiddle.

    @Vishwas

    I am integrating with React, and there I dont have

    chart.render()
    instead
    I am using CanvasJSChart component ==> <CanvasJSChart options={options} containerProps={style} />

    So, in this case how can I access options.data ? or axisX to change crosshair thickness ?

    Thanks in advance.

    @as3script,

    Glad that you figured out to get access to the chart with the help of ref :) Please take a look at React Gallery for more examples on using React Chart Component.
