Hi,
Ever wished you could access a column by its id instead of only by its
column index? For example:
var dt = new google.visualization.DataTable();
dt.addColumn('string', 'Name','name');
dt.addColumn('number', 'Size','size');
dt.addColumn('string', 'Color','size');
To access the color column, you need to use:
dt.getValue(1,2);
It would be really convenient (and more scalable across complex
projects) to use:
dt.getValue(1,'color');
If you like this idea, vote for enhancement 636:
