<title>Creating Chart HTML Tooltip</title>
		<meta http-equiv="content-type" content="text/html;charset=utf-8"/>	
			This sample uses jquery library to work with DOM elements 
		<script type="text/javascript" language="javascript" src="./js/jquery.min.js"></script>
		<script type="text/javascript" language="javascript" src="./../js/AnyChartStock.js?v=1.9.0r9317"></script>
		<script type="text/javascript" language="javascript">
			// Creating new chart object. 
			var chart = new AnyChartStock("./../swf/AnyChartStock.swf?v=1.9.0r9317", "./../swf/Preloader.swf?v=1.9.0r9317");
			// Setting XML config file.
			// Set wmode to opaque to show html elements above the chart
			chart.wMode = "opaque";
			// Set background color
			chart.bgColor = "#F8F4F0";
			// Writing the flash object into the page DOM.
			var tooltip; // link to <div id="tooltip" />
			// link to data fields in tooltip
			var tooltipDateField; 
			var tooltipValueField;
			var tooltipChangeField;
			// using jquery get DOM ready state and obtain links to elements listed above
			$(document).ready(function() {
				tooltip = $("#tooltip");
				tooltipDateField = $("#tooltipDateField");
				tooltipValueField = $("#tooltipValueField");
				tooltipChangeField = $("#tooltipChangeField");
			// object that stores absolute offset of chart.target 
			var offset;
			// as soon as chart is created - store its offset
			chart.onChartDraw = function() {
						chart.target - link to DOM element - container for the chart
						$(chart.target).offset() - absolute offset of this element
				offset = $(chart.target).offset();
				this.onChartDraw = null;
			//		Auxiliary functions to format values in tooltip
				HTML formatting of number
				Positive and zero are formatted using span of positiveValue class, negative - span of negativeValue class
			function formatNumber(val) {
				var res = Math.round(val*100)/100;
				return res >= 0 ? ("<span class=\"positiveValue\">+"+res+"</span>") : ("<span class=\"negativeValue\">"+res+"</span>");
				HTML formatting of percent change value
				Positive and zero are formatted using span of positiveValue class, negative - span of negativeValue class
				For example, for "15" output is: <span class="positiveValue">(+15%)</span>
			function formatPercentNumber(val) {
				var res = Math.round(val*100)/100;
				return res >= 0 ? ("<span class=\"positiveValue\">(+"+res+"%)</span>") : ("<span class=\"negativeValue\">("+res+"%)</span>");
				Date formatting
				Mask: %yyyy/%M/%d
				Sample: 2010/1/1
			function formatDate(date) {
				return date.getUTCFullYear()+"/"+(date.getUTCMonth()+1)+"/"+date.getUTCDate();
			//		Tooltip
				Function to update tootip content
				Structure of tooltip can be found in  <div id="tooltip"></div> at the very end of the HTML dccument
			function updateTooltip(date) {
				// get series value
				var seriesValue = chart.getSeriesValue("main","ixic");
				// get series change value
				var seriesValueChange = chart.getSeriesValueChange("main","ixic");
				// get series percent change value
				var seriesPercentChangeValue = chart.getSeriesPercentValueChange("main","ixic");
				// choose icon to show change direction 
				var changeIcon = (seriesPercentChangeValue.current < 0) ? "<img src=\"./negative_icon.gif\"/>" : "<img src=\"./positive_icon.gif\"/>";
				// show values in tooltip
				tooltipChangeField.html(changeIcon + " " + formatNumber(seriesValueChange.current) + " " +formatPercentNumber(seriesPercentChangeValue.current));				
			// Function to show tooltip
			function showTooltip() {
			// Function to hide tooltip
			function hideTooltip() {
			// Function to move tooltip
			function moveTooltip(mouseX, mouseY) {
				// uses offset, get on  onChartCreate and adds small offsets to avoid tooltip and cursor collisions
				tooltip.css("left", offset.left + mouseX + 8);
				tooltip.css("top", offset.top + mouseY + 10);
			//		Events Handling
			// listen to onChartMouseOver event
			chart.onChartMouseOver = function(chartId, date, mouseX, mouseY) {
				isChartHovered = true;
				// update tooltip info
				// move tooltip
				moveTooltip(mouseX, mouseY);
				// show it
			// listen to onChartMouseOut event
			chart.onChartMouseOut = function(chartId, date, mouseX, mouseY) {
				isChartHovered = false;
				// hide tooltip
			// listen to onChartMouseMove event
			chart.onChartMouseMove = function(chartId, date, mouseX, mouseY) {
				// update tooltip info
				// move tooltip
				moveTooltip(mouseX, mouseY);
				This flag is needed to handle mouseDown and mouseUp,
				On onChartMouseDown we hide tooltip, when chart is scrolled be dragging
				On onChartMouseUp we show tooltip only if mouse is still on the chart
			var isChartHovered = false;
			// Hide tooltip on mouse down 
			chart.onChartMouseDown = function() {
			// Show tooltip on mouse release, note isChartHovered description above
			chart.onChartMouseUp = function(chartId, date) {
				if (isChartHovered) {
					tooltip.css("display", "block");

Sample Description

How to use this sample?

Hover the chart to see custom HTML tooltip, that contains all information about series points presented in the attractive and nicely formatted way.

How it works

Besides the internal tooltips, you can create HTML-based tooltips using mouse events and some special AnyStock functions.

In this sample HTML-based tooltips are created and several events are handled (full list is available below) for this purpose - to show and hide tooltips when needed.

HTML tooltip itself is just a simple div element, that is dynamically populated with data, that is obtained using getSeriesValue, getSeriesValueChange and getSeriesPercentValueChange methods.

You can read more about events handling at Events Handling article and about functions in JavaScript API Reference.
