<apex:page > <script type="text/javascript" src="https://www.google.com/jsapi";></script> <script type="text/javascript"> google.load("visualization", "1", {packages:["corechart"]}); google.setOnLoadCallback(drawChart); function drawChart() { var data = google.visualization.arrayToDataTable([ ['ID', 'X', 'Y', 'Temperature'], ['', 80, 167, 120], ['', 79, 136, 130], ['', 78, 184, 50], ['', 72, 278, 230], ['', 81, 200, 210], ['', 72, 170, 100], ['', 68, 477, 80] ]); var options = { colorAxis: {colors: ['yellow', 'red']} }; var chart = new google.visualization.BubbleChart(document.getElementById('chart_div')); chart.draw(data, options); } </script> <div id="chart_div" style="width: 900px; height: 500px;"></div> <button onclick="saveAsImg(document.getElementById('chart_div'));">Save as PNG Image</button> <script> function getImgData(chartContainer) { alert("hiiiii"); var chartArea = chartContainer.getElementsByTagName('svg')[0].parentNode; var svg = chartArea.innerHTML; var doc = chartContainer.ownerDocument; var canvas = doc.createElement('canvas'); canvas.setAttribute('width', chartArea.offsetWidth); canvas.setAttribute('height', chartArea.offsetHeight); canvas.setAttribute( 'style', 'position: absolute; ' + 'top: ' + (-chartArea.offsetHeight * 2) + 'px;' + 'left: ' + (-chartArea.offsetWidth * 2) + 'px;'); doc.body.appendChild(canvas); canvg(canvas, svg);alert("hiiiiffffi"); var imgData = canvas.toDataURL('image/png'); canvas.parentNode.removeChild(canvas); return imgData; } function saveAsImg(chartContainer) { alert("hiiiii"); var imgData = getImgData(chartContainer); // Replacing the mime-type will force the browser to trigger a download // rather than displaying the image in the browser window. window.location = imgData.replace('image/png', 'image/octet-stream'); } </script> </apex:page> On Wednesday, 17 October 2012 20:16:36 UTC+5:30, asgallant wrote: > > See this thread: > https://groups.google.com/forum/?fromgroups=#!topic/google-visualization-api/YTD_JxX_RFc > > Note that the code linked there will never work in IE < 9, as those use > VML to draw the charts instead of SVG, and there is no way (that I know of) > to convert VML into an image file. > > On Wednesday, October 17, 2012 3:14:46 AM UTC-4, taps wrote: >> >> Hello, I have created a bubble chart based on the user selection.I need >> to save the chart in the form of image or any other way.How can save it? >> > -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
