Hi,
You can accomplish the same type of functionality with one-dimensional data
by pivoting the data and specifying the colors option on the chart. The
following bit of code should demonstrate how to do that:
function drawVisualization() {
// Create and populate the data table.
data = google.visualization.arrayToDataTable([
['', 'a', 'b', 'c', 'd', 'e', 'f'],
['', 14, 47, 80, 55, 16, 90]]);
// Create and draw the visualization.
new google.visualization.ColumnChart(document.getElementById(
'visualization')).
draw(data,
{title:"Yearly Coffee Consumption by Country",
width:600, height:400,
colors: ['f00', '0f0', '00f', 'ff0'],
hAxis: {title: "Year"}}
);
}
