When I specify formattedValue for a column, it correctly appears along
the horizontal axis. But I am unable to display formatted values along
vertical axis in my Line Chart below (it always shows numeric values
along y-axis, however, on mouseOver it displays the formatted value):
function drawChart() {
// Create our data table.
var data = new google.visualization.DataTable();
data.addColumn('string', 'Year');
data.addColumn('number', 'Rating');
data.addRow([{v:'2009 - 10'},{v:16,f:'B+'}]);
data.addRow([{v:'2008 - 09'},{v:12,f:'B'}]);
data.addRow([{v:'2007 - 08'},{v:8,f:'C'}]);
data.addRow([{v:'2006 - 07'},{v:8,f:'C'}]);
data.addRow([{v:'2005 - 06'},{v:8,f:'C'};
// Instantiate and draw our chart, passing in some options.
var chart = new
google.visualization.LineChart(document.getElementById('chart_div'));
chart.draw(data, {width: 600, height: 240, title:"Performance Graph",
curveType:'function',reverseCategories:true});
}
