Hi,
and if i create after each chart change a new error handler, must i destory
the error handler then manually after each change ?
and second question..
are there any limitations if i use a chartwrapper ?
can a chartwrapper return a view object so that i can work with a view so
that it not change the original data?
and can i use the view methods like getFilteredRows or setColumn and so on ?
and last question.. at the moment i must sometimes tranforms an Column from
type "date" to type "string" i do this with a view like that:
dataView.setColumns([{
type: 'string',
label: dataView.getColumnLabel(0),
calc: function (dt, row) {
return dt.getFormattedValue(row, 0);
}
}, 1]);
can i do the same with a charwrapper? and this operation should not change
the original dataTable..
Best regards and thx for your help
