Date Type for Chart Axis

[sfahey]

I am not sure how to use the "Time" type on a chart axis. I have tried setting a field for the date and defining it with a model type of "date" and later an axis type of "Time". I'm not sure if Ext can interpret a date like "2011-02-01", so I have also tried a timestamp like 1296540000.

In both cases if I set the type to "Time" my date axis labels are blank. I do get date axis labels if I set the type to "Category", but I would like to use the features of the "Time" type.

Here is an example of the relevant code (let me know if it isn't enough to go by):

var chartOutArray = [
      {datetime : "2011-02-01", data : "60468.045614243"},
      {datetime : "2011-02-02", data : "60056.363753319"},
      {datetime : "2011-02-03", data : "61733.438416481"},
      {datetime : "2011-02-04", data : "57087.04464817"},
      {datetime : "2011-02-05", data : "23854.768070221"}
];

or like this:

var chartOutArray = [
       {datetime : 1296540000, data : "60468.045614243"},
       {datetime : 1296626400, data : "60056.363753319"},
       {datetime : 1296712800, data : "61733.438416481"},
       {datetime : 1296799200, data : "57087.04464817"},
       {datetime : 1296885600, data : "23854.768070221"}
];

And my model:

	
Ext.regModel('out', {
	fields: [
		{name: 'datetime', type: 'date'},
		{name: 'data', type: 'float'}
	]
});

and the relevant part of the Date axis:

{
  type: 'Time',
  position: 'bottom',
  fields: ['datetime'],
  title: 'Date',
  dateFormat: 'M d',
  groupBy: 'year,month,day',
}

Am I formatting the dates wrong in my data array? Should I not set the field type to 'date'? Am I missing a crucial option in the axis' parameters? So many places to go wrong... Thanks for any help!

Just to let you know, you are not alone - I haven't been able to get a type:Time axis to display either. And the two Sencha ext-4.0-pr3 examples I've found that use a Time axis (Live Updated Chart and Live Animated Chart) don't display it either. These same examples in earlier 4.0 code (see the 09 February 2011, Countdown to Ext JS 4: Drawing and Charting, blog) did work. A little patience is required... it's a great package, and will be well worth the wait.

Same here, i get some difficulties to make work Time axis! Maybe someone have an example code ?
