That makes sense, since the Java Date object has more information in it than the JS Date object seems to have. I've never used the GWT before, so I'm not sure how to work around this.

The other issue I am having is that I am by no means a javascript expert. I guess what is happening is that the jsni new Date() doesnt' create the same object as a javascript new Date(), but i dont' know how to prove this.

I think its a bug too, but am unsure if its a gwt bug or a visualization bug. What version of gwt are you using? I am using 1.5.0

I'm having the same problem. The following won't work in GWT:

data = new $wnd.google.visualization.DataTable(); data.addColumn('date', 'Date'); data.addRows(1); data.setValue(0, 0, new Date());

I get:

com.google.gwt.core.client.JavaScriptException: (Error): Type mismatch. Value Mon Jan 01 2007 02:12:48 GMT-0500 (EST) does not match type date in column index 0

I'm thinking it's a bug. Anyone else have any insight?

Yes, someone else already pointed that out and I have fixed it, could the problem be that this is a jsni method in a gwt app?

TheDatecreation seems fine. However, when I look into your code, I see that you created the column as type 'string': data.addColumn('string', 'Date'); The type should be 'date' or 'datetime'

I think the docs state that you can only use adateordate/time object, corresponding to 'date' or 'datetime' types. How are you creating your Date objects? Can you post the code you're using?

I changed the type todateas recommended, however the error persists. Only now the error says:

com.google.gwt.core.client.JavaScriptException: (Error): Type mismatch. Value Sun Jun 22 2008 00:00:00 GMT-0500 (CDT) does not match typedatein column index 0

Is the problem that the DataTable datetype is expecting adate without the time / timezone?

Oh!

Your line "data.addColumn('string', 'Date');" should not use 'string', but 'date'.

It should be: data.addColumn('date', 'Date');

I am actually using this from a GWT app, using jsni. I am using the Table, PieChart, BarChart, and IntensityMap just fine, however the annotatedTimeLine is acting really strange. As you can see, I have removed almost any useful data and replaced it with hard coded values while debugging

I'm not sure exactly what you're asking for, but you can generate dates like this:

August 10, 2008 - newDate( 2008, 7, 10 );

January 1, 1990 - newDate( 1990, 0, 1 );

Does that help?

I am having issues getting the annotedtimeline working. In the example, it does a data.setValue(x,x,newDate(yyyy, mm dd));

However when I do this, I get a javascript error: Type mismatch. Value Sun Feb 03 2008 00:00:00 GMT-0600 (CST) does not match typedatein column index 0

now, i am _not_ a javascript guru at all, but to me this means that it is expecting adate, not adate/time/zone.

is that correct? and if so how do i generate adatethat is _only_ a datewithout the time and timezone?
