Did you specify the view in the wrapper?
var wrapper = new google.visualization.ChartWrapper({
chartType: 'ColumnChart',
containerId: 'chart3',
view: {
columns: [0,3]
}
});
Incidentally, passing a second parameter to the Dashboad#draw
call won't do anything - it doesn't accept any options:
new google.visualization.Dashboard(document.getElementById('dashboard')).
// Establish bindings, declaring the both the slider and the category
// picker will drive both charts.
bind([slider, categoryPicker, stringFilter], [pie, table, wrapper]).
// Draw the entire dashboard.
draw(data);
Those should instead be passed as the options
parameter in the appropriate ChartWrapper (likely a wrapper for a Table
, given the specified options).
