I want to show data values on the line chart, i.e. which appear on mouse over, i need them all displayed by default. I tried the solution here Google Charts API: Always show the Data Point Values in Graph
data.addColumn({type: 'number', role: 'annotation'});
I added this to my code (I'm not sure where to put it exactly) but It didn't make any change.
Here is part of my code:
<!DOCTYPE html>
<html>
<head>
<title>Week/Orders</title>
<script type="text/javascript" src="loader.js"></script>
<script type="text/javascript">
google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart(){
var data = new google.visualization.DataTable();
var data = google.visualization.arrayToDataTable([
['Week','Orders'],
<?php
while($row = mysqli_fetch_assoc($aresult)){
echo "['".$row["Week"]."', ".$row["Orders"]."],";
}
?>
]);
var options = {
title: 'Week Vs Orders',
'width':1700,
'height':600,
legend: { position: 'bottom' }
};
var chart = new google.visualization.LineChart(document.getElementById('curvechart'));
chart.draw(data, options);
}
</script>
</head>
<body>
<div id="curvechart" style="width: 900px; height: 400px"></div>

I have two values; Week and Orders. I need only the "Order" value displayed on the graph by default. How can I do this? Thanks.
you can use a DataView to add annotations to the chart
var view = new google.visualization.DataView(data);
view.setColumns([0, 1, {
calc: 'stringify',
sourceColumn: 1,
type: 'string',
role: 'annotation'
}]);
see following working snippet...
google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart(){
var data = google.visualization.arrayToDataTable([
['Week','Orders'],
['1', 5],
['2', 6],
['3', 4]
]);
var view = new google.visualization.DataView(data);
view.setColumns([0, 1, {
calc: 'stringify',
sourceColumn: 1,
type: 'string',
role: 'annotation'
}]);
var options = {
title: 'Week Vs Orders',
width: 1700,
height: 600,
legend: {position: 'bottom'}
};
var chart = new google.visualization.LineChart(document.getElementById('curvechart'));
chart.draw(view, options); // <-- use data view
}

i am using bar chart, it only display default blue color.
i have used an array which removes the column which doesnot have data(like 0)
like sorting the data
i want to display individual color for each column
like red, green any different colors for each bar
i like to add annotations also
thanks in advance
the column headings and values posted in the above comments seem to work fine here...
the only changes made...
add type property to style and annotation roles.
added different colors for style role.
see following working snippet...
var a = [['Work', 8, "#E53935", 8], ['Eat', 2, "#1E88E5", 2], ['TV', 4, "#43A047", 4]];
a.sort(compareSecondColumn);
function compareSecondColumn(a, b) {
if (a[1] === b[1]) {
return 0;
}
else {
return (a[1] > b[1]) ? -1 : 1;
}
}
google.charts.load('current', {
packages: ['corechart']
}).then(function drawChart() {
var data = google.visualization.arrayToDataTable([
['Task', 'Hours per Day', {role: 'style', type: 'string'}, {role: 'annotation', type: 'number'}],a[0],a[1],a[2]
]);
var options = {
title: 'the title',
width: 550,
height: 400,
legend: 'none'
};
var chart = new google.visualization.ColumnChart(document.getElementById('piechart'));

I've got a chart Google bar chart with currency values and I simply want to have the Y-axis formatted with £s. I've tried to explicitly set the locale using 'en' but it still displays as $. If I set other locales it does then display in the local currency for that locale ... but it doesn't seem to work for English £s.
google.charts.load('current', {packages:['corechart'], language: 'en'});
e.g. https://jsfiddle.net/ynsqwe6o/5/
use language code --> 'en-GB'
see following working snippet...
google.charts.load('current', {
packages: ['corechart'],
language: 'en-GB'
});
google.charts.setOnLoadCallback(drawStuff);
function drawStuff() {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Country');
data.addColumn('number', 'GDP');
data.addRows([
['US', 16768100],
['China', 9181204],
['Japan', 4898532],
['Germany', 3730261],
['France', 2678455]

I would like to make a visualization with the google GeoChart. I put in country codes. I would like to display the full country names but only the country code pops up.
google.charts.load('current', {
'packages': ['geochart'],
'mapsApiKey': 'AIzaSyD-9tSrke72PouQMnMX-a7eZSW0jkFMBWY'
});
google.charts.setOnLoadCallback(drawRegionsMap);
function drawRegionsMap() {
var data = google.visualization.arrayToDataTable([
['Country', 'Members'],
['LB', 3],
['JO', 2],
['IT', 24],
['PS', 3],
['LY', 1],
['TN', 6],
['LB', 3],
['EG', 2],
]);
var options = {
colorAxis: {
colors: ['#c1c1cd', '#53556e']
},
legend: 'none'
};
var chart = new google.visualization.GeoChart(document.getElementById('regions_div'));
chart.draw(data, options);
}
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<div id="regions_div" style="width: 900px; height: 500px;"></div>
using object notation,
you can provide the value (v:) and the formatted value (f:)
{v: 'IT', f: 'Italy'}
the tooltip will display the formatted value by default
update the data using object notation and provide the name as the formatted value
see following working snippet,
hover over Italy to see the result...
google.charts.load('current', {
'packages': ['geochart'],
'mapsApiKey': 'AIzaSyD-9tSrke72PouQMnMX-a7eZSW0jkFMBWY'
});
google.charts.setOnLoadCallback(drawRegionsMap);
function drawRegionsMap() {
var data = google.visualization.arrayToDataTable([
['Country', 'Members'],
['LB', 3],
['JO', 2],
[{v: 'IT', f: 'Italy'}, 24],
['PS', 3],
['LY', 1],
['TN', 6],
['LB', 3],
['EG', 2],
]);
var options = {
colorAxis: {
colors: ['#c1c1cd', '#53556e']
},
legend: 'none'
};
var chart = new google.visualization.GeoChart(document.getElementById('regions_div'));
chart.draw(data, options);
}
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>

Based on the WhiteHat's answer I added some code to automatize the introduction of the formatted values.
// iso to name conversion
// https://gist.github.com/maephisto/9228207
var isoCountries = {
'IT': 'Italy',
'JO': 'Jordan',
'LB': 'Lebanon',
};
function getCountryName(countryCode) {
if (isoCountries.hasOwnProperty(countryCode)) {
return isoCountries[countryCode];
} else {
return countryCode;
}
};
// Load the Visualization API and the corechart package.
google.charts.load('current', {
'packages': ['geochart'],
'mapsApiKey': 'AIzaSyD-9tSrke72PouQMnMX-a7eZSW0jkFMBWY'
});
// Set a callback to run when the Google Visualization API is loaded.
google.charts.setOnLoadCallback(drawRegionsMap);
// Callback that creates and populates a data table,
// instantiates the chart, passes in the data and
// draws it.
function drawRegionsMap() {
// Create the data table.
var data = new google.visualization.DataTable();
data.addColumn('string', 'Country');
data.addColumn('number', 'Members');
data.addRows([
['LB', 3],
['JO', 2],
['IT', 24],
]);
// Set chart options
var options = {
colorAxis: {
colors: ['#c1c1cd', '#53556e']
},
legend: 'none',
backgroundColor: '#efefef'
};
// Create new data table for iso and full country name
var dataMod = new google.visualization.DataTable();
dataMod.addColumn('string', 'Country');
dataMod.addColumn('number', 'Members');
// Adding rows with iso and full country name
var numRows = data.getNumberOfRows();
for (var i = 0; i < numRows; i++) {
dataMod.addRows([
[{
v: String(data.getValue(i, 0)),
f: String(getCountryName(data.getValue(i, 0)))
}, data.getValue(i, 1)],
]);
};
// Instantiate and draw our chart, passing in some options.
var chart = new google.visualization.GeoChart(document.getElementById('regions_div'));
chart.draw(dataMod, options);

I have a set of
var data = new google.visualization.arrayToDataTable([
['Month', 'Rate', 'Interest', 'Principle', 'Balance','New Balance'],
['Jan', 321, 600, 816, 319, 890],
['Feb', 163, 231, 539, 594, 678],
]);
I want to Stack and Group the above data 2 at a time (Rate,Interest), (Principle, Balance) and last one New Balance as a separate Bar. How can this be achieved in Google charts.
I am new to this whole thing..any help appreciated here is some on info to get grouping data into 2 bars how can this be improved to fit my requirement.
How to make a grouped bar stack with Google charts?
using the option isStacked, if set to true, stacks the elements for all series at each domain value.
this means the values for all columns for each row will be displayed in one stack
as such, to create separate stacks, the data will need to be separated into rows
something like the following working snippet...
google.charts.load('current', {
callback: drawChart,
packages: ['corechart']
});
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Month\nCategory', 'Bottom', 'Top'],
['Rate / Interest', 321, 600],
['Principle / Balance\nJan', 816, 319],
['New Balance', 890, null],
['Rate / Interest', 163, 231],
['Principle / Balance\nFeb', 539, 594],
['nNew Balance', 678, null],
]);
var options = {
height: 400,
isStacked: true,
legend: 'none',
width: 800
};
var chartDiv = document.getElementById('chart_div');
var chart = new google.visualization.ColumnChart(chartDiv);
chart.draw(data, options);

I've added Google chart to my page. This returns an images of a charts. It is ok. But I want to edit only one of them and this is problem. It edit only the first one, but I want to edit for example only the second one. Can anybody help me? Here is my code:
//draw charts
google.charts.load('current', {'packages': ['corechart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Value');
data.addColumn('number', 'Total count');
data.addRows([
["A", 4],
["B", 1],
]);
var options = {
title: "Choose something"
};
var chart = new google.visualization.PieChart(document.getElementById(304));
chart.draw(data, options);
var data305 = new google.visualization.DataTable();
data305.addColumn('string', 'Value');
data305.addColumn('number', 'Total count');
data305.addRows([
["Male", 2],
["Female", 2],
]);
var options305 = {
title: "Gender"
};
var chart305 = new google.visualization.PieChart(document.getElementById(305));
chart305.draw(data305, options305);
}
//edit charts
google.load('visualization', '1.0', {packages: ['charteditor']});
var chartEditor = null;
function loadEditor() {
// Create the chart to edit.
var data = new google.visualization.DataTable();
data.addColumn('string', 'Value');
data.addColumn('number', 'Total count');
data.addRows([
["A", 4],
["B", 1],
]);
var wrapper = new google.visualization.ChartWrapper({
chartType: 'PieChart',
dataTable: data,
options: {'title': 'Pohlavi'},
containerId: '304'
});
chartEditor = new google.visualization.ChartEditor();
google.visualization.events.addListener(chartEditor, 'ok', redrawChart);
chartEditor.openDialog(wrapper, {});
//---------------------------------------
// Create the chart to edit.
var data305 = new google.visualization.DataTable();
data305.addColumn('string', 'Value');
data305.addColumn('number', 'Total count');
data305.addRows([
["Male", 2],
["Female", 2],
]);
var wrapper305 = new google.visualization.ChartWrapper({
chartType: 'PieChart',
dataTable: data,
options: {'title': 'Pohlavi'},
containerId: '305'
});
chartEditor305 = new google.visualization.ChartEditor();
google.visualization.events.addListener(chartEditor305, 'ok', redrawChart);
chartEditor.openDialog(wrapper305, {});
}
// On "OK" save the chart to a <div> on the page.
function redrawChart(inputId){
chartEditor.getChartWrapper().draw(document.getElementById(304));
}
function redrawChart305(inputId){
chartEditor305.getChartWrapper().draw(document.getElementById(305));
}
and here ienter code heres my html:
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<button onclick="loadEditor()">Click me</button>
<div id="304" style="height: 400px; width: 600px;"></div>
<button onclick="loadEditor()">Click me</button>
<div id="305" style="height: 400px; width: 600px;"></div>
<div id="vis_div" style="height: 400px; width: 600px;"></div>
Where is mistake?
Thanks
