In your CategoryFilters, you can set a default selection by setting the
state.selectedValues parameter:
var statePicker = new google.visualization.ControlWrapper({
'controlType': 'CategoryFilter',
'containerId': 'control1',
'options': {
'filterColumnLabel': 'State',
'ui': {
'labelStacking': 'vertical',
'allowTyping': false,
'allowMultiple': false
}
},
state: {
selectedValues: [/* array of values to have selected by default */]
}
});
