Question

How can i place values on the ‘google.visualization’ graph ?

please see image attached.

var options = {
      width: 1024, height: 240,
      title: 'Clicks from Welcome email',
      vAxis: {title: 'email Clicks',  titleTextStyle: {color: 'black'}}
    };

this is the solution

data.addColumn({type:’number’, role:’annotation’});

in the google graph its all about layers, so i added this layer,
watch out that the type is the same type as in your rowData

var data = new google.visualization.DataTable();
data.addColumn(‘string’, ‘date’);
data.addColumn(‘number’, ‘Remove’);
data.addColumn({type:’number’, role:’annotation’}); // annotation role col.
data.addColumn(‘number’, ‘Add’);
data.addColumn({type:’number’, role:’annotation’}); // annotation role col.
data.addRows([]);

This type of functionality was recently introduced to gviz using DataTable roles: you can use extra columns of information in your datatable to create annotations and other types of functionality.

See the first example here for a guide to what I think you want:
