Position Image over Chart

In this tutorial we are going to describe how to position custom images over a chart.

Here are the steps:


Create a basic chart with required options and call chart.render() method to render the chart.

var chart = new CanvasJS.Chart("chartContainer",{
	title :{
		text: "Position Image over chart"
	data: [{
		type: "column",
		dataPoints : [
			{ label: "apple",  y: 10  },
			{ label: "orange", y: 15  },
			{ label: "banana", y: 25  },
			{ label: "mango",  y: 30  },
			{ label: "grape",  y: 28  }


Append images to the Div element with class “canvasjs-chart-container”. This is a div created dynamically by CanvasJS inside the chartContainer created in Step 1. It holds all the Chart elements including canvas, tooltip, buttons etc.

$('img').attr('src', url)
        .attr("class", label)
        .css({"display": "none"})


Get pixel co-ordinates where the images have to be placed using convertValueToPixel method. Once you have co-ordinates, images can be positioned relative to the div.

imageBottom = chart.axisX[0].bounds.y1;
imageCenter = chart.axisX[0].convertValueToPixel(chart.data[0].dataPoints[0].x);

image.css({"position": "absolute", 
           "display": "block",
           "top": imageBottom  - fruit.height(),
           "left": imageCenter - fruit.width()/2


To summarize, you should first render the chart and then calculate pixel co-ordinates where images have to be placed (using convertValuetoPixel method) and then set top & left css properties of images.
