Adding Chart to InfoWindow

[DanikBourdeau2]

I'm trying to add a chart to an InfoTemplate but I can't seem to get it to return the chart.  Here is my code:

dojo.require("dojox.charting.themes.Julie"); dojo.require("dojox.charting.Chart2D"); dojo.require("dojox.charting.plot2d.Pie"); dojo.require("dojox.charting.action2d.Highlight"); dojo.require("dojox.charting.action2d.MoveSlice"); dojo.require("dojox.charting.action2d.Tooltip");  //Setting the InforTemplate for Layer var mtenTemplate = new esri.InfoTemplate(); mtenTemplate.setTitle("Mining Tenement ${tenid}"); mtenTemplate.setContent(getWindowContent);  function getWindowContent(graphic) {      var c = dojo.create("div", {         id: "demoChart"     }, dojo.create('div'));      var chart = new dojox.charting.Chart2D(c);          chart.setTheme(dojox.charting.themes.Julie);     chart.addPlot("default", {         type: "Pie",         radius: 70,         htmlLabels: true     });     chart.addSeries("Percentage of Tenement Covered by DIA Sites", [{         y: graphic.attributes.DIA_Perc,         tooltip: graphic.attributes.DIA_Perc,         text: 'DIA Sites Area'     }, {         y: graphic.attributes.Not_DIA_P,         tooltip: graphic.attributes.Not_DIA_P,         text: 'Area Not Covered'     }]);     new dojox.charting.action2d.Highlight(chart, "default");     new dojox.charting.action2d.Tooltip(chart, "default");     new dojox.charting.action2d.MoveSlice(chart, "default");      return "<b>Holder</b> " + graphic.attributes.holder1 +  "<br/><b>Tenement ID:</B> " + graphic.attributes.tenid + "<br/><b>Tenement Status:</b> " + graphic.attributes.tenstatus +  "<br/><b>Tenement Type:</b> " + graphic.attributes.type + "<br/><b>Tenement Area sqKm:</b> " + graphic.attributes.Area_sqKm +  "<br/><b>Number of DIA Sites:</b> " + graphic.attributes.DIA_S_Num + "<br/><b>DIA Sites Area sqKm:</b> " + graphic.attributes.DIA_S_Area +  "<br/><br/><b>Area Distribution</b><hr/>" + c; }

My function returns the contents of the InfoWindow where I want the chart to be at the bottom.  I know I have to add chart.render() somewhere but I don't know where.  I've tried many different combinations, any help would be much appreciated.

Thanks,

You should review this ESRI sample to get you started. Although the sample's tabbed interface inside the infoWindow complicates a little, the basic workflow is there-

1. Create a dojo container


2. Create your chart DIV


3. create your chart (last line of this code block would be your chart.render()


4. Insert the chart element into your dojo container


5. Finally, at the end of your infoWindow content function, return the dojo container's node: return dContent.domNode;

Here's a full showContent function example of mine that inserts a chart into an infoWindow. I'm sorry it's a little complex but hopefully you can see what you need to see from it:

function raceByBlockgroupContent(graphic) {  var theTextContent;   theTextContent = "<table cellpadding=\"3\"><tr><td colspan=\"3\" style=\"background:#5495D6; font-weight:bold;font-size:125%;color:white\">" + graphic.attributes.pctMinor + "% of the population within this block group identified with a race other than white.</td></tr>";  theTextContent = theTextContent + "<tr><td>1.</td><td>White Alone:</td><td>" + dojo.number.format(graphic.attributes.B02001004) + "</td></tr>";  theTextContent = theTextContent + "<tr><td>2.</td><td>Black or African American Alone:</td><td>" + dojo.number.format(graphic.attributes.B02001007) + "</td></tr>";  theTextContent = theTextContent + "<tr><td>3.</td><td>American Indian and Alaska Native Alone:</td><td>" + dojo.number.format(graphic.attributes.B02001010) + "</td></tr>";  theTextContent = theTextContent + "<tr><td>4.</td><td>Asian Alone:</td><td>" + dojo.number.format(graphic.attributes.B02001013) + "</td></tr>";  theTextContent = theTextContent + "<tr><td>5.</td><td>Native Hawaiian and Other Pacific Islander Alone:</td><td>" + dojo.number.format(graphic.attributes.B02001016) + "</td></tr>";  theTextContent = theTextContent + "<tr><td>6.</td><td>Some Other Race Alone:</td><td>" + dojo.number.format(graphic.attributes.B02001019) + "</td></tr>";  theTextContent = theTextContent + "<tr><td>7.</td><td>Two or More Races:</td><td>" + dojo.number.format(graphic.attributes.B02001022) + "</td></tr>";  theTextContent = theTextContent + "<tr><td>8.</td><td>Two Races Including Some Other Race:</td><td>" + dojo.number.format(graphic.attributes.B02001025) + "</td></tr>";  theTextContent = theTextContent + "<tr><td>9.</td><td style=\"border-bottom: 1px solid #000000\">Two Races Excluding Some Other Race, and Three or More Races:</td><td style=\"border-bottom: 1px solid #000000\">" + dojo.number.format(graphic.attributes.B02001028) + "</td></tr>";  theTextContent = theTextContent + "<tr><td colspan=\"2\" style=\"font-weight:bold;font-style:italic;font-size:115%\">TOTAL POPULATION:</td><td style=\"font-weight:bold;font-style:italic;font-size:115%\">" + dojo.number.format(graphic.attributes.B02001001) + "</td></tr></table>";   var cp1 = new dijit.layout.ContentPane({    title: "Details",    style: "height: 100%;

That's some great code!  Thanks for sharing Steve.

I didn't realize that I had to create a ContenPane, I figured it was implicit in the InfoWindow.  Got it to work :), thanks again.
