I'm trying to trigger the creation of a new BarChart with Google's Chart API when a user clicks on a particular bar. I think I understand the concepts, and wanted to at least get the getSelection() function to work and display what bar the user clicked on. But everytime, when you click on the bar, it just freezes with the display and no java alert. Any thoughts?
Here's the code:
<script type="text/javascript">
google.setOnLoadCallback(drawChart);
function drawChart() {
var visualization = new google.visualization.BarChart(document.getElementById('acctmeta'));
var json_data = new google.visualization.DataTable({{acctmeta_json}});
visualization.draw(json_data, {width: 850, height: 600, title: 'Collection Level Populated Metadata Fields',
chartArea: {width:"50%"},
vAxis: {title: 'Collection Title/ID', titleTextStyle: {color: 'green'}},
hAxis: {logScale:false, title:'Fields Populated', titleTextStyle: {color: 'green'}}
});
// Add our selection handler.
google.visualization.events.addListener(visualization, 'select', selectHandler);
// The selection handler.
// Loop through all items in the selection and concatenate
// a single message from all of them.
function selectHandler() {
alert(data.getValue(chart.getSelection()[0].row, 0));
}
} //end of draw chart function
</script>
Just wondering, should the line
alert(data.getValue(chart.getSelection()[0].row, 0));
be
alert(data.getValue(visualization.getSelection()[0].row, 0));
?
Here is a working example of mine. I had to set data and chart as global variables:
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load('visualization', '1.0', {'packages':['corechart']});
google.setOnLoadCallback(drawChart);
var data;
var chart;
function drawChart() {
data = new google.visualization.DataTable();
data.addColumn('string', 'Where');
data.addColumn('number', 'What');
data.addRows([['ABC',87],['ERT',70],['KLJ',38],['UPP',-67],['SSD',27],['UKG',42],['NUS',60],['WEB',96]]);
var options = {'title':'my chart','width':'600','height':'400','is3D':'true'};
chart = new google.visualization.ColumnChart(document.getElementById('test3_chart'));
chart.draw(data, options);
google.visualization.events.addListener(chart, 'select', selectHandler2);
}
function selectHandler2() {
var selection = chart.getSelection();
alert('That\'s column no. '+selection[0].row);
}
</script>
</head>
<body style="font-family: Arial;border: 0 none;">
<div id=test3_chart>Please wait...</div>

I'm trying to use Google Charts and seem to be running into issues with titles not displaying. Im using a Column Chart and the vAxis title is not displaying. I also started to make a Material Line Chart and I'm running into the same issue.

Any help is greatly appreciated!
Material charts are in beta and you must use a converter function on your options to ensure they work properly. Here is an example:
chart.draw(data, google.charts.Line.convertOptions(options));
For your column chart, you must explicitly set the vaxis.title option like so:
vAxis: { title: 'Average mAh', gridlines: { count: 8 }, minValue: 500}
I'm creating a chart in Google Script and couldn't set the vAxis title either, and similarly couldn't modify some other attributes.
I found success by modifying vAxes[0] instead.
chart.setOption('vAxes', {0: {title: 'title Text'} } )
or if you're using an options variable:
vAxes: { 0: { title: 'Milliamp Hours' } }
Hope this helps anyone with the same issue.
I have tried to pass some array data to google charts but it says not enough columns to draw chart.here is my code.

var data1=someStr.replace(/(["'])(\d+)\1/g,"$2")
console.log(data1);
var data = google.visualization.arrayToDataTable([['year'],[data1]]);
console.log(data);

</html>
Please help me to do this.
Thank in advance.
Your data has two columns: Month and a Number. ("JAN","1088626")
But you're only providing a header for one column: year
Plus, you need to pass an actual array to arrayToDataTable. (not a string)
Try something like this...
google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var someStr = '["JAN","1088626"],["FEB","1478093"],["MAR","1232870"],["APR","1151634"],["MAY","1083623"],["JUN","740591"],["JUL","769227"],["AUG","1162995"],["SEP","951794"],["OCT","884736"],["NOV","500902"],["DEC","1221438"]';
var data1 = JSON.parse('[' + someStr.replace(/(["'])(\d+)\1/g,"$2") + ']');
// data array - add two column headings to data1
data1.splice(0, 0, ['month', 'number']);
// data table
var data = google.visualization.arrayToDataTable(data1);
// chart options
var options = {
title: 'My Daily Activities',
is3D: true
};
// chart
var chart = new google.visualization.PieChart(document.getElementById('piechart_3d'));
chart.draw(data, options);
}
<script src="https://www.google.com/jsapi"></script>
<div id="piechart_3d" style="width: 900px; height: 500px;"></div>
You are getting this error since invalid input data is passed into google.visualization.arrayToDataTable function. The provided regex /(["'])(\d+)\1/g fails while parsing the input string, i would suggest to parse input string with JSON.parse function.
google.visualization.PieChart object expects data to be provided in
the following format:
var data = google.visualization.arrayToDataTable([
['Name', 'Value'],
['<name1>', <value1>],
['<name2>', <value2>],
['<name3>', <value3>],
...
['<namen>', <valuen>]
]);
Below is provided the modified example:
google.load("visualization", "1", { packages: ["corechart"] });
google.setOnLoadCallback(drawChart);
function drawChart() {
var stringData = '["JAN","1088626"],["FEB","1478093"],["MAR","1232870"],["APR","1151634"],["MAY","1083623"],["JUN","740591"],["JUL","769227"],["AUG","1162995"],["SEP","951794"],["OCT","884736"],["NOV","500902"],["DEC","1221438"]';
var data = JSON.parse("[" + stringData + "]");
data = data.map(function (item) {
item[1] = parseInt(item[1]);
return item;
});
data.splice(0, 0, ['year', 'hours']);
var dataTable = google.visualization.arrayToDataTable(data);
var options = {
title: 'My Daily Activities',
is3D: true,
};
var chart = new google.visualization.PieChart(document.getElementById('piechart_3d'));
chart.draw(dataTable, options);

I am trying to draw a bar chart using google visualization. I have 11 categories, out of those eleven categories 4 of them have subcategories. The Subcategories are different for different categories. For example:
a) Video
i. Subcategories: Netflix, YouTube, Vimeo, Vine,
DailyMotion
b) Email & Messaging
i. Subcategories: gmail, hotmail,
yahoomail
. . .
My requirement is, when onclick of one category on bar chart, the subcategories will display as another bar chart.
Can this be possible using google visualization? Please let me know.
Or is there any other way i can handel this?
Here is a really simple example of what you can do:
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Category', 'Value'],
['Videos', 1000],
['Mail', 1170]
]);
var chart = new google.visualization.BarChart(document.getElementById('chart_div'));
google.visualization.events.addListener(chart, 'select', function(){
var selection=chart.getSelection();
if(selection.length == 1){
var row = selection[0].row;
var col = selection[0].column;
var cat = data.getValue(row,0);
drawSubChart(cat);
}
})
chart.draw(data, {});
}
function drawSubChart(cat){
var arr = [['SubCategory', 'Value']];
if(cat == 'Videos'){
arr.push(['Youtube', 700], ['DailyMotion', 300]);
}else if(cat == 'Mail'){
arr.push(['Gmail', 600], ['Hotmail', 570]);
}
var data = google.visualization.arrayToDataTable(arr);
var chart = new google.visualization.BarChart(document.getElementById('chart_div2'));
chart.draw(data, {});
}
<script type="text/javascript" src="https://www.google.com/jsapi?autoload={'modules':[{'name':'visualization','version':'1','packages':['corechart']}]}"></script>
<div id="chart_div" style="width: 500px; height: 300px;"></div>
<div id="chart_div2" style="width: 500px; height: 300px;"></div>
I wanted to enable users to filter the results being displayed on the chart. Google API provides CategoryFilter which enforces filtering by rows. Here is my code which works perfectly fine
<html>
<head>

}

});
var chart = new google.visualization.ChartWrapper({

vAxis: {title: 'Jumlah Kategori', titleTextStyle: {color: 'blue'}}
}
});
// Create the dashboard.
new google.visualization.Dashboard(document.getElementById('dashboard')).
// Configure the controls so that:
// - the 'Country' selection drives the 'Region' one,

}
</script>
</head>
<body>
<div id="dashboard">
<div id="negeri"></div>
<div id="chart_div"></div>
</div>
</body>
</html>
However in my datatable, I would also want to filter by columns. These two types of filtering should work together. (dependent; by bind() function). I have referred to #asgallant http://jsfiddle.net/asgallant/WaUu2/ and that is the feature that I wanted to combine with.
How can I possibly combine them? I have tried combining setChartView() by #asgallant with google's dashboard() but it's not working.

You want to bind your countryPicker filter to the chart as normal, but do not bind the columnFilter control to anything - the setChartView function handles everything for the columnFilter. You need to tweak a couple other lines to make it work with a dashboard, but nothing major. This is what it should look like:
function drawChart() {
// Create our data table out of JSON data loaded from server.
var data = new google.visualization.DataTable(<?=$jsonTable?>);
var columnsTable = new google.visualization.DataTable();
columnsTable.addColumn('number', 'colIndex');
columnsTable.addColumn('string', 'colLabel');
var initState= {selectedValues: []};
// put the columns into this data table (skip column 0)
for (var i = 1; i < data.getNumberOfColumns(); i++) {
columnsTable.addRow([i, data.getColumnLabel(i)]);
// you can comment out this next line if you want to have a default selection other than the whole list
initState.selectedValues.push(data.getColumnLabel(i));
}
var countryPicker = new google.visualization.ControlWrapper({
controlType: 'CategoryFilter',
containerId: 'negeri',
dataTable: data,
options: {
filterColumnLabel: 'Negeri',
ui: {
labelStacking: 'vertical',
allowTyping: false,
allowMultiple: true
}
},
// Define an initial state, i.e. a set of metrics to be initially selected.
state: {'selectedValues': ['Kedah', 'Johor']}
});
var columnFilter = new google.visualization.ControlWrapper({
controlType: 'CategoryFilter',
containerId: 'colFilter_div',
dataTable: columnsTable,
options: {
filterColumnLabel: 'colLabel',
ui: {
label: 'Kategori Sukan',
allowTyping: false,

});

vAxis: {title: 'Jumlah Kategori', titleTextStyle: {color: 'blue'}}
}
});
// Create the dashboard.
var dashboard = new google.visualization.Dashboard(document.getElementById('dashboard')).
bind(countryPicker, chart);
function setChartView () {
var state = columnFilter.getState();
var row;
var view = {
columns: [0]
};
for (var i = 0; i < state.selectedValues.length; i++) {
row = columnsTable.getFilteredRows([{column: 1, value: state.selectedValues[i]}])[0];
view.columns.push(columnsTable.getValue(row, 0));
}
// sort the indices into their original order
view.columns.sort(function (a, b) {
