I'm generating some Google Charts and I'm stuck here. Google allows you to have your columns stacked. But it's either limited or I can't configure it to work. Taken from Google, here is an example showing number of cups of coffee produced in each year for two countries:
Say I have another data set for the same two countries, but this time I have instant coffee instead of ground. Example:
What I'd like to do is to stack these two datasets on top of each other. So each column would be a single country, but two divisions: bean and instant coffee.
I was thinking if there was a way of formatting the data table in the following way:
['Year', 'Austria', 'Austria (instant)', 'Bulgaria', 'Bulgaria (instant')],
['2003', 1736060, 10051, 250361, 68564],
['2004', 1338156, 65161, 786849, 1854654],
['2005', 1276579, 65451, 120514, 654654]
to generate something like
Your help is appreciated.
I just ran into this same issue today and followed your submission link. It seems that just recently someone replied with this:
"This is actually possible with the new Material Bar chart (albeit in a somewhat roundabout way). In the new chart, if you make a chart stacked, but place some series on a different axis, that creates a separate stack for those series. Unfortunately, there is currently no way to completely hide an axis yet, and you will have to explicitly set the view window. Eventually we will introduce options to hide axes and to align view windows, but this will have to do for now."
This fiddle seemed to help me solve this problem: http://jsfiddle.net/p7o0pjgg/
Here's the code:
google.load('visualization', '1.1', {
'packages': ['bar']
});
google.setOnLoadCallback(drawStuff);
function drawStuff() {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Topping');
data.addColumn('number', 'Nescafe Instant');
data.addColumn('number', 'Folgers Instant');
data.addColumn('number', 'Nescafe Beans');
data.addColumn('number', 'Folgers Beans');
data.addRows([
['2001', 321, 621, 816, 319],
['2002', 163, 231, 539, 594],
['2003', 125, 819, 123, 578],
['2004', 197, 536, 613, 298]
]);
// Set chart options
var options = {
isStacked: true,
width: 800,
height: 600,
chart: {
title: 'Year-by-year coffee consumption',
subtitle: 'This data is not real'
},
vAxis: {
viewWindow: {
min: 0,
max: 1000
}
},
series: {
2: {
targetAxisIndex: 1
},
3: {
targetAxisIndex: 1
}
}
};
// Instantiate and draw our chart, passing in some options.
var chart = new google.charts.Bar(document.getElementById('chart_div'));
chart.draw(data, google.charts.Bar.convertOptions(options));
};
