I'm using the Google visualization chart in my application for drawing a line chart. It works great except one thing in the hAxis the entered number converts itself to thousands like below. I know this is happening because im trying to display huge numbers but still i would like to know if there is way to get around this?
Code
<html>
<head>
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load('visualization', '1.1', {packages: ['line']});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('number', 'Degree Level');
data.addColumn('number', 'Graduate or professional degree');
data.addColumn('number', "Bachelor's degree");
data.addColumn('number', "Associate's degree");
data.addColumn('number', "High school or vocational training");
data.addRows([
[2, 39758,93179, 78578,49141],
[3, 100747, 300646, 220982,100456],
[4, 49964, 68022, 21092,6943],
[5, 150370, 124868, 27120,8204]
]);
var options = {
chart: {
title: 'Education Report',
subtitle: 'distributed by experience'
},
width: 900,
height: 500
};
var chart = new google.charts.Line(document.getElementById('linechart_material'));
chart.draw(data, options);
}
</script>
</head>
<body>
<div id="linechart_material"></div>
</body>
</html>
Output
Can someone let me know how can i make the hAxis to display in number?
There are two solutions to get the format that you want.
Either you use version 1 of the corecharts package :
so load the package like this :
// instead of : google.load('visualization', '1.1', {packages: ['line']});
google.load('visualization', '1', { packages: ['corechart'] });
and call your chart like this :
// instead of : var chart = new google.charts.Line(document.getElementById('linechart_material'));
var chart = new google.visualization.LineChart(document.getElementById('linechart_material'));
And you'll get what you want.
See a demo jsfiddle here.
Or alternatively,
Use version 1.1 of the package (you already do in your example) like this :
google.load('visualization', '1.1', {packages: ['line']});
and then specify in your chart options the vAxis format like this :
vAxis: { format: '###,###,###' },
and load the chart this way, so that the vAxis settings are taken into account :
chart.draw(data, google.charts.Line.convertOptions(options));
That'll work too.
See a demo jsfiddle here.
The problem here is that the way options are defined has changed from v.1 to v.1.1. So if you want to use the v.1.1 package you have to call google.charts.Line.convertOptions() for your options to be interpreted correctly.

This error occurs on this line:
chart.draw(data, google.charts.Line.convertOptions(options));
the error is:
Cannot read property 'vB' of undefined
the error is beautifully rendered by Google's Chart API like so:
the error appears to be internal to the Google Chart library. My code is as follows, it's working for one server I am using, but not for another server and I cannot figure out why this error is happening!
<html>
<head>
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<script type="text/javascript">
debugger;
google.charts.load('current', {'packages': ['line']});
google.charts.setOnLoadCallback(drawChart);
{
var to;
window.addEventListener('resize', function (event) {
clearTimeout(to); // throttle this call
if( window.memvizIsReady){
to = setTimeout(drawChart, 500);
}
});
}
function drawChart() {
window.memvizIsReady = true;
var data = new google.visualization.DataTable();
data.addColumn('number', 'Time unit');
data.addColumn('number', 'RSS');
data.addColumn('number', 'Heap Total');
data.addColumn('number', 'Heap Used');
data.addRows(JSON.parse('{{{aa}}}'));
var options = {
hAxis: {title: "Entry every {{{ms}}} milliseconds."},
vAxis: {title: "Memory in Megabytes", format: 'decimal'},
chart: {
title: 'Node.js memory usage (RSS, Heap Used, Heap Total)',
subtitle: '(In megabytes.)'
},
width: window.innerWidth - (window.innerWidth)/20,
height: window.innerHeight - (window.innerHeight)/20,
axes: {
x: {
0: {side: 'top'}
}
}
};
var chart = new google.charts.Line(document.getElementById('line_top_x'));
chart.draw(data, google.charts.Line.convertOptions(options));
}
</script>
</head>
<body>
<div id="line_top_x"></div>
</body>
</html>
does anyone know what this error might be about? using the boolean memvizIsReady should prevent calling drawChart() before things are ready.
I was able to debug, and get the raw data going into this call:
the data looks like:
ughhh, f*cking Google..this happens when no data is collected yet.
data.addRows([]);
is what is happening, and apparently Google simple fails if there is no data. That's not good, am going to report them to developer jail.
Does Google Visualization allow on-load animations for pie charts? So far I have only been able to get on-load animations for column charts, but not for pie charts, bar charts, line charts or even a Google table chart for that matter.
this is the pie chart that I am trying to animate on-load:
<div id="piechart" style="width: 800px; height: 500px;"></div>
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load("visualization", "1", { packages: ["corechart"] });
google.setOnLoadCallback(drawChart);
function drawChart() {
var data1 = google.visualization.arrayToDataTable([
['FacultyName', 'SubmissionID'],
#Html.Raw(rows)]);
var options = {
title: '',
animation: {
duration: 1000,
startup: true
}
};
var chart = new google.visualization.PieChart(document.getElementById('piechart'));
chart.draw(data1, options);
</script>
However the animate option doesn't seem to take place.
I have a bunch of sheets that I'm using to store the marks of my students for a couple of my classes. On my website, I am using HTML and Google's Query Language to pull info from the sheets (2 columns...the students numbers of each student and their mark). If I've edited the spreadsheet on any given day, the chart shows up properly, but if I have not edited it that day then it shows incorrect values for their marks or old values for their marks. I think it's something to do with the sheets, but I can't be sure.
Here's the HTML code from my site:
<html>
<head>
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load("visualization", '1', {packages:['corechart']});
google.setOnLoadCallback(drawChart);
function drawChart() {
var query = new google.visualization.Query(
'https://docs.google.com/spreadsheet/ccc?key=14mPTcYYraMyuBnEFSJW74ZQ3xjWSSOuDqoxB2VrvAvw&tq=select%20D%2C%20E%20where%20D%3C%3E%22Avatar%22%20order%20by%20E%20desc%20label%20E%20%22Experience%20Points%22');
query.send(handleQueryResponse);
}
function handleQueryResponse(response) {
if (response.isError()) {
alert('Error in query: ' + response.getMessage() + ' ' + response.getDetailedMessage());
return;
}
var data = response.getDataTable();
var chart = new google.visualization.ColumnChart(document.getElementById('columnchart'));
var options = {'title':'Experience Points',
'width':'927',
'height':'510',
'chartArea': {'left':'50', 'width':'90%'},
legend: { position: 'top', maxLines: 2 },
hAxis: {showTextEvery: 1, slantedText: true, slantedTextAngle: 90, viewWindow:{max:33}},
bar:{groupWidth: '60%'},
isStacked: true};
chart.draw(data, options);
}
</script>
<title>Data from a Spreadsheet</title>

<body>

Any ideas? By the way, the sheet is set so that anyone on the internet can find and view.
I am working on Google-visualization chart. I would like that when i select particular area of chart i can zoom that particular selected area. I would also like it to do the same with line chart, bar chart, pie chart

As far as I know, and looking through the config options, you should be able to use an option called explorer
// before you pass the options to the drawing function
options.explorer = {
actions: ['dragToZoom', 'rightClickToReset']
/* you can add more options */
}
Please take a look at the explorer and other options in the line chart API and read the notes
Note: The explorer only works with continuous axes (such as numbers or dates).
So your example domain column data must be transformed into actual Date objects, and your first column should be defined as
data.addColumn('date','Date');
or my preferred way
data.addColumn({role:'domain', type:'date', label:'Date'});
If you do this you have to use explorer.actions . In Google Area chart
The Google Charts explorer supports three actions
dragToPan: Drag to pan around the chart horizontally and vertically.
To pan only along the horizontal axis, use explorer: { axis: 'horizontal' }. Similarly for the vertical axis.
dragToZoom: The explorer's default behavior is to zoom in and out when the user scrolls. If explorer: { actions: ['dragToZoom', 'rightClickToReset'] } is used, dragging across a rectangular area zooms into that area. Google recommend using rightClickToReset whenever dragToZoom is used. See
explorer.maxZoomIn, explorer.maxZoomOut, and explorer.zoomDelta for zoom customizations.
rightClickToReset: Right clicking on the chart returns it to the original pan and zoom level

I'm trying to use google visualization api in jboss seam 2 project.
I have created a simple example which is actually taken from Google Quick Start page.
<html>
<head>
<!--Load the AJAX API-->

<script type="text/javascript">
// Load the Visualization API and the piechart package.
google.load('visualization', '1.0', {'packages':['corechart']});
// Set a callback to run when the Google Visualization API is loaded.
google.setOnLoadCallback(drawChart);
// Callback that creates and populates a data table,
// instantiates the pie chart, passes in the data and
// draws it.
function drawChart() {
// Create the data table.
var data = new google.visualization.DataTable();
data.addColumn('string', 'Topping');
data.addColumn('number', 'Slices');
data.addRows([
['Mushrooms', 3],
['Onions', 1],
['Olives', 1],
['Zucchini', 1],
['Pepperoni', 2]
]);
// Set chart options
var options = {'title':'How Much Pizza I Ate Last Night',
'width':400,
'height':300};
// Instantiate and draw our chart, passing in some options.
var chart = new google.visualization.PieChart(document.getElementById('chart_div'));

When I open it as file in web browser it works nicely. But when I put it to my Jboss Seam 2 project and open in web browser, it generates an error message "b[c] is undefined" on red background.
And here what I see when I open page source in browser:

As you can see Jboss Seam adds some other script srcs for a4j.
Is it possible that a4j javascript conflicts with google visualization api javascript?
Is there any idea how to resolve this?
Finally found the solution here
Google charts error:Cannot read property 'length' of undefined; Debugging error in Google Charts
and here
http://code.google.com/p/google-visualization-api-issues/issues/detail?id=501 .
Adding the following hack in the beginning of the script:
Array.prototype.reduce = undefined;
or more gracefully:
Array.prototype.reduce=function(fun){var len=this.length>>>0;if(typeof fun!="function")throw new TypeError;if(len==0&&arguments.length==1)throw new TypeError;var i=0;if(arguments.length>=2)var rv=arguments[1];else{do{if(i in this){var rv=this[i++];break}if(++i>=len)throw new TypeError;}while(true)}for(;i<len;i++)if(i in this)rv=fun.call(undefined,rv,this[i],i,this);return rv};
solves the problem!
