I have an array of json objects:
var data = [
{date: "12/27/2012", resolver: "Group 1", volume: 15, escalation: 90, bubble: 5},
{date: "12/27/2012", resolver: "Group 2", volume: 85, escalation: 30, bubble: 1},
{date: "12/27/2012", resolver: "Group 3", volume: 130, escalation: 10, bubble: 1},
{date: "12/27/2012", resolver: "Group 4", volume: 240, escalation: 10, bubble: 1}
];
I need to determine the max value of the "volume" field among these objects.
What is the proper syntax for this?
