### Direction minimizer - other usages

In Minimizing maps directionfinder api calls I showed how to make the most of your directions API quota in the context of a spreadsheet. Here's an example of calling it directly, say when you are working on a map viz and need to work on some directions and geocoding.

You can take a copy of this sheet and the code at https://docs.google.com/spreadsheet/ccc?key=0At2ExLh4POiZdFpHWXF1UGR1NnlhU21Rd0trTW45dFE&usp=sharing

#### Example

Let's say we have a list of destinations and one start point, and want to sort the destinations in order of distance from the start point, and return coordinate, distance and driving time to each of these destinations. Using the functions in Minimizing maps directionfinder api calls, this becomes fairly trivial

`function tryThis () {`

`   var result = routeDistanceWaypointsFetch(`
`      ['New york','Los Angeles',"San Francisco","vancouver","chicago"],`
`      ['seattle'],`
`      {mode:'driving',apiKey:'', useMiles:true, maxWayPoints:8}`
`    );`
`  `
`    Logger.log( JSON.stringify(`
`      Object.keys(result).map ( function(p) { `
`        return result[p]; `
`      })`
`      .sort (function(a,b) {`
`        return (a.distance - b.distance) ;`
`      })`
`      .map (function(p) {`
`        if (p.swapped) {`
`          return {`
`            from : { place:p.a, coords:p.start},`
`            to: { place:p.b, coords:p.end},`
`            distance: p.distance,`
`            duration: p.duration`
`          }`
`        }`
`        else {`
`           return {`
`            from : { place:p.b, coords:p.end},`
`            to: { place:p.a, coords:p.start},`
`            distance: p.distance,`
`            duration: p.duration`
`          }`
`        }`
`      })`
`    ));`
`}`

Gives this result
