How to add a point inside the Google Charts Visualization: Area chart like the red point in the picture shown above and can i put some label above or beside the point?
Here is the code that outputs the chart above
google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Output1');
data.addColumn('number', 'Height');
data.addColumn({type:'string', role:'annotation'});
data.addRows([
<?php echo"['', 2, null],"; ?>
<?php echo"['', 2, '1 Kpa ---------->'],"; ?>
<?php echo"['2', 1, '<---------- 2'],"; ?>
<?php echo"['3 σ', 0, '<---------- 3 σ']"; ?>
]);
var options = {
title: 'Total Stress',
hAxis: {title: '<-------- Direction', titleTextStyle: {color: '#333'}},
vAxis: { ticks: [{v:2, f:'1 Kpa ->'}, {v:1, f:'1 m'},{v:0, f:'length ^ 1 m'},{v:0, f:'1 m'}] }
};
var chart = new google.visualization.AreaChart(document.getElementById('total_stress'));
chart.draw(data, options);
}
you can use a ComboChart to combine series types
add another column to the data table for the point
in the options, define the series types, use 'scatter' for points
seriesType: 'area',
series: {
1: {
type: 'scatter'
}
}
see following working snippet...
google.charts.load('current', {
packages: ['corechart']
}).then(function () {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Output1');
data.addColumn('number', 'Height');
data.addColumn({type:'string', role:'annotation'});
data.addColumn('number', 'Scatter');
data.addRows([
['', 2, null, null],
['', 2, '1 Kpa ---------->', 1],
['2', 1, '<---------- 2', null],
['3 s', 0, '<---------- 3 s', null]
]);
var options = {
title: 'Total Stress',
hAxis: {title: '<-------- Direction', titleTextStyle: {color: '#333'}},
vAxis: { ticks: [{v:2, f:'1 Kpa ->'}, {v:1, f:'1 m'},{v:0, f:'length ^ 1 m'},{v:0, f:'1 m'}] },
seriesType: 'area',
series: {
1: {
type: 'scatter'
}
}
};
var chart = new google.visualization.ComboChart(document.getElementById('chart_div'));
chart.draw(data, options);
});

i'm trying to use Google Chart API for building an Waterfall chart. I noticed that Candlestick/Waterfall charts are not supporting the annotations.
See this jsfiddle sample
google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Category');
data.addColumn('number', 'MinimumLevel');
data.addColumn('number', 'MinimumLevel1');
data.addColumn('number', 'MaximumLevel');
data.addColumn('number', 'MaximumLevel1');
data.addColumn({type: 'number', role: 'tooltip'});
data.addColumn({type: 'string', role: 'style'});
data.addColumn({type: 'number', role: 'annotation'});
data.addRow(['Category 1', 0 , 0, 5, 5, 5,'gray',5]);
data.addRow(['Category 2', 5 , 5, 10, 10, 10,'red',10]);
data.addRow(['Category 3', 10 , 10, 15, 15, 15,'blue',15]);
data.addRow(['Category 4', 15 , 15, 10, 10, 10,'yellow',10]);
data.addRow(['Category 5', 10 , 10, 5, 5, 5,'gray',5]);
var options = {
legend: 'none',
bar: { groupWidth: '60%' } // Remove space between bars.
};
var chart = new google.visualization.CandlestickChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
I would like to put the value of the 5th column at the top of every candlestick.
It should look like this :
Is there a way to do this?
Thanks
I add annotations to candlestick charts by adding annotations to a hidden scatter plot. You can set exactly where you want the annotations to sit by changing the plot.
google.charts.load('current', { 'packages': ['corechart'] });
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('date', 'Date');
data.addColumn('number', 'Low');
data.addColumn('number', 'Open');
data.addColumn('number', 'Close');
data.addColumn('number', 'High');
data.addColumn('number'); //scatter plot for annotations
data.addColumn({ type: 'string', role: 'annotation' }); // annotation role col.
data.addColumn({ type: 'string', role: 'annotationText' }); // annotationText col.
var high, low, open, close = 160;
for (var i = 0; i < 10; i++) {
open = close;
close += ~~(Math.random() * 10) * Math.pow(-1, ~~(Math.random() * 2));
high = Math.max(open, close) + ~~(Math.random() * 10);
low = Math.min(open, close) - ~~(Math.random() * 10);
annotation = '$' + close;
annotation_text = 'Close price: $' + close;
data.addRow([new Date(2014, 0, i + 1), low, open, close, high, high, annotation, annotation_text]);
}
var view = new google.visualization.DataView(data);
var chart = new google.visualization.ComboChart(document.querySelector('#chart_div'));
chart.draw(view, {
height: 400,
width: 600,
explorer: {},
chartArea: {
left: '7%',
width: '70%'
},
series: {
0: {
color: 'black',
type: 'candlesticks',
},
1: {
type: 'scatter',
pointSize: 0,
targetAxisIndex: 0,
},
},
candlestick: {
color: '#a52714',
fallingColor: { strokeWidth: 0, fill: '#a52714' }, // red
risingColor: { strokeWidth: 0, fill: '#0f9d58' } // green
},
});

just so happens, i ran into the same problem this week
so I added my own annotations, during the 'animationfinish' event
see following working snippet...

Here is a code for creating a line chart. I'm trying to add an image on top of the line annotation. Here a demo on jsfiddle.
Here is the code:
google.charts.load('current', {packages: ['corechart', 'line']});
google.charts.setOnLoadCallback(drawBasic);
function drawBasic() {
var data = new google.visualization.DataTable();
data.addColumn('number', 'X');
data.addColumn({type: 'string', role: 'annotation'});
data.addColumn('number', 'Dogs');
data.addColumn('number', 'Cats');
data.addRows([
[0,null, 0, 1], [1,'', 10,3], [2,null, 23,6], [3,null, 17,7], [4,null, 18,4], [5,null, 9,7]
]);
var options = {
curveType : 'function',
hAxis: {
title: 'Time',
gridlines: {
color: 'transparent'
}
},
vAxis: {
title: 'Popularity',
gridlines: {
color: 'transparent'
}
},
annotations: {
style: 'line',
position: 'top'
}
};
var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
I really can't figure out how to do this. Any one ever done this ?
you can add elements to the chart, once the 'ready' event fires
(or 'animationfinish' when using animation)
first, need to find the annotations, which will be <rect> elements
similar to the axis lines, they will have a 'width' of 1
but they will have a different 'fill' attribute
(keep this in mind, if more style settings are set on the annotations option)
the following working snippet finds the annotation lines and adds an image to the top
google.charts.load('current', {
callback: drawBasic,
packages: ['corechart']
});
function drawBasic() {
var data = new google.visualization.DataTable();
data.addColumn('number', 'X');
data.addColumn({type: 'string', role: 'annotation'});
data.addColumn('number', 'Dogs');
data.addColumn('number', 'Cats');
data.addRows([
[0, null, 0, 1],
[1, '', 10, 3],
[2, null, 23, 6],
[3, null, 17, 7],
[4, null, 18, 4],
[5, null, 9, 7]
]);
var options = {
annotations: {
position: 'top',
style: 'line'
},
hAxis: {
gridlines: {
color: 'transparent'
},
title: 'Time'
},
vAxis: {
gridlines: {
color: 'transparent'
},
title: 'Popularity'
},
};
var container = document.getElementById('chart_div');
var chart = new google.visualization.LineChart(container);
google.visualization.events.addListener(chart, 'ready', function () {
Array.prototype.forEach.call(container.getElementsByTagName('rect'), function(rect) {
if ((rect.getAttribute('width') === '1') && (rect.getAttribute('fill') === '#999999')) {
var xPos = parseFloat(rect.getAttribute('x'));
var yPos = parseFloat(rect.getAttribute('y'));
var whiteHat = container.appendChild(document.createElement('img'));
whiteHat.src = 'http://findicons.com/files/icons/512/star_wars/16/clone_old.png';
whiteHat.className = 'whiteHat';
// 16x16 (image size in this example)
whiteHat.style.top = (yPos - 8) + 'px';
whiteHat.style.left = (xPos) + 'px';
}
});
});
chart.draw(data, options);
}
.whiteHat {
border: none;
position: absolute;
}
<script src="https://www.gstatic.com/charts/loader.js"></script>
<div id="chart_div"></div>
Add 'role': 'tooltip', 'p': {'html': true}}); in your data.addColumn and
in the options use: tooltip: { isHtml: true }.
HTML:
<div id="chart"></div>
JavaScript:
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('number', 'y');
data.addColumn('number', 'Line 1');
data.addColumn({'type': 'string', 'role': 'tooltip', 'p': {'html': true}});
data.addColumn('number', 'Line 2');
data.addRow([1, 1, '<img src="https://www.google.com/images/srpr/logo6w.png" style="width:30px;height:50px"/>', 2]);
data.addRow([2, 2,'<img src="https://www.google.com/images/srpr/logo6w.png" style="width:30px;height:50px"/>', 4]);
data.addRow([3, 3,'<img src="https://www.google.com/images/srpr/logo6w.png" style="width:30px;height:50px"/>', 6]);
data.addRow([4, 4,'<img src="https://www.google.com/images/srpr/logo6w.png" style="width:30px;height:50px"/>', 8]);
data.addRow([5, 5,'<img src="https://www.google.com/images/srpr/logo6w.png" style="width:30px;height:50px"/>', 10]);
var options = {
title: 'Graph',
hAxis: {
title: 'Time',
gridlines: {
color: 'transparent'
}
},
vAxis: {
title: 'Popularity',
gridlines: {
color: 'transparent'
}
},
annotations: {
style: 'line',
position: 'top'
},
tooltip: {isHtml: true},
};
var chart = new google.visualization.LineChart(document.getElementById('chart'));
chart.draw(data, options);
}
google.load("visualization", "1", {
packages: ["corechart"]
});
google.setOnLoadCallback(drawChart);

Folks,
I was trying to create a Column Chart using google chart API and I am having lots of issue in getting Y-AXIS line.
I understand x-axis is string that is why vertical grid line is not coming but Y-axis line must come. I am marking in RED as of now this line is not coming.
I have following code.
function drawChartSecond(resp) {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Activity');
data.addColumn('number', 'Hours');
data.addRows([
['Work', 11],
['Eat', 2 ],
['Commute', 2 ],
['Watch TV', 2],
['Sleep', 7]
]);
var options = {
title : '',
legend: {
position: 'right',
alignment: 'center'
},
tooltip: {
isHtml: true
},
hAxis: {
title: 'Activity',
titleTextStyle: {
color: 'Black',
fontSize : '12',
fontName : 'Arial'
},
baselineColor: '#CCCCCC'
},
chartArea : {
left: '8%',
top: '8%',
height:'70%',
width:'100%'
}
};
var chart = new google.visualization.ColumnChart(document.getElementById('chartdivsecond'));
chart.draw(data, options);
}
The only way to get that baseline is to use a chart with a continuous axis. You can use a DataView to convert your data to appropriately formatted numbers, and use the hAxis.ticks option to re-label the axis tick marks so it looks correct:
function drawChartSecond(resp) {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Activity');
data.addColumn('number', 'Hours');
data.addRows([
['Work', 11],
['Eat', 2 ],
['Commute', 2 ],
['Watch TV', 2],
['Sleep', 7]
]);
var view = new google.visualization.DataView(data);
view.setColumns([{
type: 'number',
label: data.getColumnLabel(0),
calc: function (dt, row) {
return {v: row + 1, f: dt.getValue(row, 0)};
}
}, 1]);
var ticks = [];
for (var i = 0; i < data.getNumberOfRows(); i++) {
ticks.push({v: i + 1, f: data.getValue(i, 0)});
}
var options = {
title : '',
legend: {
position: 'right',
alignment: 'center'
},
tooltip: {
isHtml: true
},
hAxis: {
title: 'Activity',
titleTextStyle: {
color: 'Black',
fontSize : '12',
fontName : 'Arial'
},
baselineColor: '#CCCCCC',
ticks: ticks
},
chartArea : {
left: '8%',
top: '8%',
height:'70%',
width:'100%'
}
};
var chart = new google.visualization.ColumnChart(document.getElementById('chartdivsecond'));
chart.draw(view, options);
}
see working example: http://jsfiddle.net/asgallant/6mXkv/
I have a google scatter, and I would like when mouse is over on circle then open a info window containing a custom string.
for example in tutorial https://developers.google.com/chart/interactive/docs/events#Event_Listeners
when click on circle open a info window with a custom string.
Thanks
EDIT:
I try this code:
function drawChart() {
var dataTable = new google.visualization.DataTable();
dataTable.addColumn('number', 'SVD1');
dataTable.addColumn('number', 'SVD2');
dataTable.addColumn('number', 'SVD3');
// A column for custom tooltip content
dataTable.addColumn({type: 'string', role: 'tooltip'});
dataTable.addRows([
[2010, 600, null ,'test1'],
[2011, 1500, null , 'test2'],
[2012, null, 800, 'test3'],
[2013, null, 1000, 'test4']
]);
var options = {
tooltip: {isHtml: true},
legend: 'none'
};
var chart = new google.visualization.ScatterChart(document.getElementById('chart_div'));
chart.draw(dataTable, options);
}
Using tooltip the Strings "test 3" and "test4" appear right. The string "test1" and " "test2" disappear. Why???
I found it!!! Βelow give a solution to the problem.
Sample Code:
function drawChart() {
var dataTable = new google.visualization.DataTable();
dataTable.addColumn('number', 'SVD1');
dataTable.addColumn('number', 'SVD2');
dataTable.addColumn({type: 'string', role: 'tooltip'});
dataTable.addColumn('number', 'SVD3');
// A column for custom tooltip content
dataTable.addColumn({type: 'string', role: 'tooltip'});
dataTable.addRows([
[2010, 600, 'test1' ,null, null],
[2011, 1500, 'test2' ,null, null ],
[2012, null, null, 800, 'test3'],
[2013, null, null, 1000, 'test4']
]);
var options = {
tooltip: {isHtml: true},
legend: 'none'
};
var chart = new google.visualization.ScatterChart(document.getElementById('chart_div'));
chart.draw(dataTable, options);
}
