Info window with chart

Description

This sample shows how to add a Dojo widget to an info window. At 2.2 the InfoTemplate's setContent can be set to a function. In this snippet a new InfoTemplate is created and assigned to a feature layer.

var template = new esri.InfoTemplate();
template.setTitle("<b><img src='../images/flags/${STATE_ABBR}.png'/> ${STATE_NAME}</b>");
template.setContent(<span style='background-color:yellow;'>getWindowContent</span>);

Instead of creating the info window's content when the template is defined a function getWindowContent is defined that will generate the content when the associated feature is clicked.

The getWindowContent function provides access to the clicked graphic and its attribute information which we can use to build a dojo pie chart showing the percentage of males and females in the clicked state. The return value of the function is the newly created dom node that contains a tabbed container with attribute information in one tab and a Dojo chart in the other.

var tc = new dijit.layout.TabContainer({
style
: "height: 100%; width: 100%;"
}, dojo.create("div"));

var cp2 = new dijit.layout.ContentPane({
title
: "Pie Chart"
});
tc
.addChild(cp2);

var chart = new dojox.charting.Chart2D(cp2.domNode);
chart
.addPlot("default",{type:"Pie"});
chart
.addSeries("PopulationSplit",[{y:male,text:'Male'},{y:female,text:'Female'}]);

return tc.domNode;
