You can set colors for series only. In some cases (depending on what you
want to do with your chart and data), it is possible to hack together a
kludgy solution that end-routs the problem. To do so, define a second
series, and assign it the second color. With your data, break it up into
two groups, depending on what color you want the bars to be. If the bar
should be the first color, assign that value to the first series, and a zero
to the second series. If it should be the second color, assign a zero to
the first series and the value to the second series. Set the chart option
"isStacked" to true, and draw the chart:
function drawVisualization() {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Location');
data.addColumn('number', 'Foo');
data.addColumn('number', 'Foo');
data.addRows(3);
data.setValue(0, 0, 'Value 1');
data.setValue(0, 1, 1239);
data.setValue(0, 2, 0);
data.setValue(1, 0, 'Value 2');
data.setValue(1, 1, 913);
data.setValue(1, 2, 0);
data.setValue(2, 0, 'Value 3');
data.setValue(2, 1, 0);
data.setValue(2, 2, 549);
var options = {
width: 600,
height: 600,
title: 'Chart Title',
colors: ['#7b1315','#6b999f'],
legend: 'none',
isStacked: true
};
// Create and draw the visualization.
new google.visualization.ColumnChart(document.
getElementById('visualization')).draw(data, options);
}
Value 1 and Value 2 will be the first color, Value 3 will be the second.
