Hi,
i use a chartWrapper to display different charts (Line,Colum,Area,Pie and
so on) and i can filter dates and numbers without any problem but if i
switch to discrete mode then the filtering did no longer work..
i build the filter view for my DataWrapper like this:
Data:
> date,New York,San Francisco,Austin,Country
> 20111001,10,20,30,A
> 20111002,40,50,60,B
> 20111003,70,80,90,C
> 20111004,100,110,120,D
var dataTable=new google.visualization.DataTable(DATA);
> var filteredView ={columns : 1,2,3, rows :
> dataTable.getFilteredRows([{column:1, minValue: 40, maxValue: 70}])};
For example i want filter on the xAxis (New York) all values between 40
and 70.. this works if i have no discrete mode..
but if i change the Column "New York" from type number to string (is this
the only method to activate the discrete mode? or is there an option where
i must not change the type ? ) the filtering did not work. I do the
switching to discrete mode like that:
var View =[
> {
> type: 'string',
> label: dataTable.getColumnLabel(1),
> calc: function (dt, row) {
> return dt.getFormattedValue(row, 1);
> }
> }
> ];
> View .push.apply(View ,[2,3]); //Adds the values
> from a second array to the first array
> var newView={columns: View }; /
i have the same problem with the PieChart, there is per default the first
column a string so i can not do any filtering.
how can i solve this problem ?
