How to Make Your Own

Start by dragging out AM|Charts from the components menu
Resize it to the desired size
Drag out another component nearby (in the example we are using a button)
Select the AM|Chart and the other component and right click, and create group
Delete the other component, so it is just the AM|Chart in the group
Tag the group (ex. pieChartAM)

Next we will add the Program

Go to programs in the left menu
Click the plus to add a new program, and it will pull up the program editor
In the Program Target Filter type the tag applied to your group (our example above was pieChartAM)
Click the three dots in the top right corner, and select variables
Click the + icon to add a new Variable
Click the gear that appears as you hover over the new variable
On the first line type point, and on the second line type id==$virtualPointRef
Click the gray save button
Copy and paste the code below into the main section
Click the blue save

finstack.eval(point.query, function(data){
queryData=data.result.toObj();
queryData.forEach(function (item)
{
    item.curValPretty   = GetPrettyValue(item);   
});
function handleZoom(ev){
var myPointId = ev.dataItem.dataContext.id;
top.app.ShowRelatedBubbles(myPointId,myPointId,false);
}
var chart = AmCharts.makeChart(Chart.view, {
"type": "pie",
"theme": "light",
"dataProvider": queryData,
"valueField": "curVal",
"titleField": "navName",
"balloonText": "[[navName]]: <b>[[curValPretty]]</b>",
"balloon":{
"fixedPosition":true
},
"export": {
"enabled": true
},
"listeners": [ {
"event": "clickSlice",
"method": handleZoom
}]
} );
});

Set the Query

Under Properties → advanced

Add string tag query (to group/model) with value set to the query

Call the tag query and set the value to the query

var test = template.view.querySelector("#pieChart");
function handleZoom(ev){
var myPointId = ev.dataItem.dataContext.id;
top.app.ShowRelatedBubbles(myPointId,myPointId,false);
}
var chart = AmCharts.makeChart(test, {
"type": "pie",
"theme": "light",
