PieChart configuration

[Iker Jericó]

Hi guys,

I just started using this library after a couple of days reading the Analytics and Chart Tools API and I must say you guys made an incredible job making our lifes easier when it comes to working with the API, thanks a lot!

That being said, I have a really beginner question, but after several tries I haven't been able to figure how to solve it. When it comes to extracting data from analytics and rendering it to a graph, we have this example in the user documentation page:

// Create a new Chart that queries visitors for the last 30 days and plots
    // visualizes in a line chart.
    var chart1 = new gadash.Chart({
      'type': 'LineChart',
      'divContainer': 'line-chart-example',
      'last-n-days':30,
      'query': {
        'ids': TABLE_ID,
        'metrics': 'ga:visitors',
        'dimensions': 'ga:date'
      },
      'chartOptions': {
        height:600,
        title: 'Visits in January 2011',
        hAxis: {title:'Date'},
        vAxis: {title:'Visits'},
        curveType: 'function'
      }
    }).render();



But when it comes to rendering a PieChart, I always get the same error: PieChart should have a first column of type String. I assume it means the labels, but can't figure how to put it in the config array. Could somebody put a configuration based on the previous code of a working PieChart please?

My code looks like this:

var chart2 = new gadash.Chart({
      'type': 'PieChart',
      'divContainer': 'pie-chart-example',
      'query': {
        'ids': TABLE_ID,
		'start-date':'2012-07-01',
  		'end-date':'2012-08-01',
        'metrics': 'ga:percentNewVisits',
        'dimensions': 'ga:date',
		'sort': 'ga:date'
      },
      'chartOptions': {
		height:600,
                title: 'Title'
		//legend: 'right'
      }
    }).render();

I know it is a really beginner question, but I would really appreciate the help and maybe its useful for future users too.

Omg, no sooner had I posted this than I found the answer myself...

It seems I had a problem with the dimension, I changed ga:date to ga:month and it works like a charm. Really annoyed with myself for not having thought about it before!
