i have faced the problem while creating triple y-axis in google charts .
The problem is space between right side axis. could you please help me.
i provided the following code snippet. In result, right y-axes are merged .could you provide what is way to give space /gap between them to look good. Thank you

i'm thinking this feature was intended for no more than two vAxes,
although it does appear to work, there aren't any config options to handle this
if you must have three, try textPosition
have one 'in' and the other 'out'
see following example...
google.charts.load('current', {
callback: function () {
var data = new google.visualization.DataTable();
data.addColumn('date', 'Month');
data.addColumn('number', "Average Temperature");
data.addColumn('number', "Average Hours of Daylight");
data.addColumn('number', "Average 1");
data.addColumn('number',"Average 2")
data.addRows([
[new Date(2014, 0), -.5, 8.7,7,11],
[new Date(2014, 1), .4, 8.7,5,12],
[new Date(2014, 2), .5, 12,6,13],
[new Date(2014, 3), 2.9, 15.7,5,14],
[new Date(2014, 4), 6.3, 18.6,8,15],
[new Date(2014, 5), 9, 20.9,8,16],
[new Date(2014, 6), 10.6, 19.8,9,16],
[new Date(2014, 7), 10.3, 16.6,7,15],
[new Date(2014, 8), 7.4, 13.3,8,14],
[new Date(2014, 9), 4.4, 9.9,12,13],
[new Date(2014, 10), 1.1, 6.6,11,12],
[new Date(2014, 11), -.2, 4.5,11,11]
]);
var classicOptions = {

chartArea: {

},
series: {
0: {targetAxisIndex: 0},
1: {targetAxisIndex: 1},
2: {targetAxisIndex: 2}
},
vAxes: {
0: {
textPosition: 'out',
title: 'Temps (Celsius)'
},
1: {
textPosition: 'in',

viewWindow: {

},
2: {

How can I extract row entry width of Google Chart

I'm having difficulty extracting the width of a selected row on a Google Gantt chart. To further elaborate I need the width of the singular data row, which I can see in the code behind under the 'rect' tag however not sure how to properly call the syntax for width retrieval.
ganttchart

first, wait for the chart's 'ready' event to fire.
then we can get the <rect> elements from the chart.
there will be other <rect> elements, besides those that represent a row.
such as the chart area, etc.
we can filter those out by fill color...
google.visualization.events.addOneTimeListener(chart, 'ready', function () {
var rows = container.getElementsByTagName('rect');
var bars = [];
Array.prototype.forEach.call(rows, function(row) {
switch (row.getAttribute('fill')) {
case '#ffffff':
case '#f5f5f5':
case 'none':
// ignore
break;
default:
bars.push(row);
}
});
if (bars.length > 0) {
console.log(parseFloat(bars[0].getAttribute('width')));
}
});
see following working snippet...
google.charts.load('current', {
packages:['gantt']
}).then(function () {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Task ID');
data.addColumn('string', 'Task Name');
data.addColumn('string', 'Resource');

Change color text gantt chart google ( javascript ) without CSS

How can i change the left text color without use or insert a css ?
This code is the same as documentation.
I know colors depend on resources. I would not change the colors of the activity bars but only the text associated with it.

<div id="chart_div"></div>
one option would be to change the color manually using script
first, need to identify the row labels from the bottom date labels
to do so, test the label value exists in the data table column for 'Task Name'
use data table method --> getFilteredRows
the only problem with changing the color manually,
the chart will change the color back to its original,
anytime there is activity, such as hovering a row and / or row label
as such, need to use a MutationObserver, or something,
to keep the new color
see following working snippet...

Google Charts API custom month names

I need to set custom month names in Charts.
How set custom month names in Google Charts API?

You can specify custom ticks on the hAxis...
google.load('visualization', '1', {packages: ['corechart']});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('date', 'Time of Day');
data.addColumn('number', 'Rating');
data.addColumn({type: 'string', role: 'tooltip'});
data.addRows([
[new Date(2015, 1, 1), 5, 'January'],
[new Date(2015, 2, 1), 7, 'February'],
[new Date(2015, 3, 1), 3, 'March'],
[new Date(2015, 4, 1), 2, 'April'],
[new Date(2015, 5, 1), 2, 'May']
]);
var options = {
width: 900,
height: 500,
hAxis: {
format: 'MMM',
gridlines: {count: 5},
ticks: [
{v: new Date(2015, 1, 1), f:'custom 1'},
{v: new Date(2015, 2, 1), f:'custom 2'},
{v: new Date(2015, 3, 1), f:'custom 3'},
{v: new Date(2015, 4, 1), f:'custom 4'},
{v: new Date(2015, 5, 1), f:'custom 5'}
]
},
vAxis: {
gridlines: {color: 'none'},
minValue: 0
}
};
var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
<script src="https://www.google.com/jsapi"></script>
<div id="chart_div"></div>

Multiple trendlines in Google Charts

I need to add multiple trendlines to my google line chart but I just can't figure out how to do it with more than one line.
Here is my code example with a single line based on a date and value to build the chart:
<html>
<head>
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
function drawMultipleTrendlineChart() {
var chart;
var data = new google.visualization.DataTable();
data.addColumn('date', 'Date');
data.addColumn('number', 'Sales value');
data.addRow([new Date(2013, 3, 11), 10]);
data.addRow([new Date(2013, 4, 02), 650]);
data.addRow([new Date(2013, 5, 03), 55]);
data.addRow([new Date(2013, 6, 04), 95]);
data.addRow([new Date(2013, 7, 05), 400]);
data.addRow([new Date(2013, 8, 06), 600]);
data.addRow([new Date(2014, 0, 07), 800]);
data.addRow([new Date(2014, 1, 08), 900]);
data.addRow([new Date(2014, 2, 09), 3127]);
var formatter = new google.visualization.NumberFormat({
fractionDigits: 2,
prefix: 'R$:'
});
formatter.format(data, 1);
var dateFormatter = new google.visualization.NumberFormat({
pattern: 'MMM yyyy'
});
dateFormatter.format(data, 0);
var chartHeight = 400;
var chartWidth = 600;
var chartOptions = {
tooltip:{isHtml: true},
trendlines: {
0: {color: 'red'}
},
title: 'Trendlines with multiple lines',
isStacked: true,
width: chartWidth,
height: chartHeight,
colors: ['#0000D8'],
hAxis: {
title: 'example title',
slantedText: false,
slantedTextAngle: 45,
textStyle: {
fontSize: 10
},
format: 'dd-MM-yyyy'
},
chartArea: {
left: 100,
top: 20,
width: (chartWidth - 10),
height: (chartHeight - 90)
}
};
chart = new google.visualization.LineChart(document.getElementById('multipleTrendChart'));
chart.draw(data, chartOptions);
}
google.load('visualization', '1', {packages:['corechart'], callback: drawMultipleTrendlineChart});
</script>
</head>
<body>
<div id="multipleTrendChart"></div>
</body>
I wan't to do it like this image:Image_example
jsfiddle example: http://jsfiddle.net/w3ez9gwb/

Just add more columns of your data:
var data = new google.visualization.DataTable();
data.addColumn('date', 'Date');
data.addColumn('number', 'Sales value A');
data.addColumn('number', 'Sales value B');
data.addRows([
[new Date(2013, 3, 11), 100, 10],
[new Date(2013, 4, 02), 50, 650],
[new Date(2013, 5, 03), 70, 55],
[new Date(2013, 6, 04), 80, 95],
[new Date(2013, 7, 05), 50, 400],
[new Date(2013, 8, 06), 10, 600],
[new Date(2014, 0, 07), 20, 800],
[new Date(2014, 1, 08), 300, 900],
[new Date(2014, 2, 09), 100, 312]
]);
Then add the trendlines to your chart options like so:
var chartOptions = {
tooltip: {
isHtml: true
},
trendlines: {
0: {
color: 'red'
},
1: {
color: 'yellow'
},
},
...
};
