I've been trying to add annotations to google bar chart. I've seen related questions about this, but can't solve it. There are 2 bar in charts and i want to show numbers on bars. I added 2 annotation column to my datatable. Chart draw works without annotations and there is no error at console. So i need some help. Here is my code:
var options = {
chart: {
title: 'xxxx',
subtitle: 'xxxx',
focusTarget:'category'
},
annotations: {
textStyle: {
color: 'black',
fontSize: 11,
},
alwaysOutside: true
},
height:300,
vAxis: {format: 'short'},
colors: ['#17807E', '#4285F4']
};
function drawAudits(Data) //data comes from another function with ajax call
{
var dataTbl = new google.visualization.DataTable();
dataTbl.addColumn('string', 'Months');
dataTbl.addColumn('number', 'Scheduled');
dataTbl.addColumn('number', 'Done');
dataTbl.addColumn({ type:'number' , role: 'annotation' });
dataTbl.addColumn({ type:'number' , role: 'annotation' });
for (var i = 0; i < Data.length; i++)
{
dataTbl.addRow([Data[i].month, Data[i].AllAudits, Data[i].DoneAudits, Data[i].AllAudits, Data[i].DoneAudits]);
} //last 2 column for annotations
var chart = new google.charts.Bar(document.getElementById('columnChartDiv'));
chart.draw(dataTbl,options);
}
thanks in advance.
annotations.* are not supported by Material charts, along with several other options...
see --> Tracking Issue for Material Chart Feature Parity #2143
the following option will style Core charts, similar to Material...
theme: 'material'
note: the annotation column should directly follow the series it represents...
see following working snippet...
google.charts.load('current', {
callback: function () {
var options = {
annotations: {
textStyle: {
color: 'black',
fontSize: 11,
},
alwaysOutside: true
},
chartArea: {
left: 36,
width: '100%'
},
colors: ['#17807E', '#4285F4'],
focusTarget:'category',
height:300,
legend: {
position: 'bottom'
},
theme: 'material',
title: 'xxxx',
vAxis: {
format: 'short',
viewWindow: {
max: 12
}
},
};
drawAudits();
window.addEventListener('resize', drawAudits, false);
function drawAudits(Data) {
var dataTbl = new google.visualization.DataTable();
dataTbl.addColumn('string', 'Months');
dataTbl.addColumn('number', 'Scheduled');
dataTbl.addColumn({ type:'number' , role: 'annotation' });
dataTbl.addColumn('number', 'Done');
dataTbl.addColumn({ type:'number' , role: 'annotation' });
Data = [
{month: 'Jan', AllAudits: 10, DoneAudits: 5},
{month: 'Feb', AllAudits: 10, DoneAudits: 6}
];
for (var i = 0; i < Data.length; i++) {
dataTbl.addRow([Data[i].month, Data[i].AllAudits, Data[i].AllAudits, Data[i].DoneAudits, Data[i].DoneAudits]);
}
var chart = new google.visualization.ColumnChart(document.getElementById('columnChartDiv'));
chart.draw(dataTbl,options);
}
},
packages: ['corechart']

I am using google charts and showing 3 tooltips by default when chart is loaded for that i have used
tooltip: { trigger: 'selection' },
aggregationTarget: 'none',
selectionMode: 'multiple'
Every thing is working fine but when the points get very close to each other like (1,1) and (1,1.5) the tool tips comes over each other please see this image. Is there any option or a way to overcome this.
google.charts.load('current', {

there are no options you can set to avoid overlap...
a possible solution would be to use the explorer option to pan and zoom
explorer: {
actions: ['dragToZoom', 'rightClickToReset']
}
see following working snippet, when the chart loads,
use the mouse to draw a square around the two points on the lower left,
once zoomed, both tooltips are displayed fully...

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

Could anyone let me know which is the best method to show/hide line legends (If using a checkbox for changing the visibility).
I should be having maximum 7 legends in line chart.
My code is below:
function DrawGraph(chartsdata, title, charttype) {
//debugger;
google.charts.load('current', { 'packages': ['corechart'] });
google.charts.setOnLoadCallback(DrawChart);
function DrawChart() {
var data = new google.visualization.DataTable();
data.addColumn('string', '');
data.addColumn('number', '');
try {
var data = google.visualization.arrayToDataTable(chartsdata);
}
catch (e) {
//debugger;
//document.writeln(e);
}
var optionsBar = {
title: title,
isStacked: true,
hAxis: {
type: "datetime",
showTextEvery: 1,
ticks: [2016,2017,2018,2019,2020,2021,2022,2023]
},
legend: {
position: 'bottom',
textStyle: { fontSize: 12 }
}
};
var optionsLine = {
title: title,
//width: 500,
seriesType: 'line',
legend: {
position: 'bottom',
textStyle: { fontSize: 11 }
}
};
if (charttype == "line") {
var chart = new google.visualization.LineChart(document.getElementById('chartdiv'));
chart.draw(data, optionsLine);
}
else {
var chart = new google.visualization.ColumnChart(document.getElementById('chartdiv'));
chart.draw(data, optionsBar);
}
}
}
Toggle the legend by using none/bottom as the position:
legend: {position: 'none'} //to hide
While creating a stacked column chart using google charts, the annotations are getting overlapped due to large amount data. Is there anyway to get it adjusted. Like displaying only for every 3rd column. I know this concept works fine with highcharts but I was looking for free charts.
Annotation function call is :--
function drawVisualization() {
var json;
$.getJSON('end.json', function (json) {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Time');
data.addColumn('number', 'Run 3');
data.addColumn({ type: 'number', role: 'annotation' });
data.addColumn('number', 'Run 2');
data.addColumn({ type: 'number', role: 'annotation' });
data.addColumn('number', 'Run 1');
data.addColumn({ type: 'number', role: 'annotation' });
for (var i = 0; i< json[0].data.length; i++){
data.addRow([json[0].data[i], json[3].data[i],json[3].data[i],json[2].data[i],json[2].data[i],json[1].data[i], json[1].data[i]]);
}
var options = {
title: "End to End Processing",
tooltip: {isHtml: true},
legend:{position:"right"},
isStacked:true,
height:window.innerHeight,
width: window.innerWidth,
bar: {groupWidth: '3'},
focusTarget: 'category',
vAxis: {
viewWindowMode:'explicit',
viewWindow: {
max:60,
min:0
},
gridlines :{count:6},
title:'Time in mins',
format: 'short'
},
hAxis: {
format: 'd/m/y',
textStyle : {
fontSize: 9
},
slantedText: true,
slantedTextAngle: 270
},
annotations: {
textStyle: {
color: 'black',
fontSize: 11,
fontStyle: 'bold'
},
stemLength: 20,
displayAnnotationsFilter: true,
legendPosition: 'newRow'
},
series: {
0:{color:'lightgreen'},
1:{color:'black'},
2:{color:'#1E90FF',},
3:{ type: 'line', lineWidth: 0, visibleInLegend:false, pointSize: 0}
}
}
var chart = new google.visualization.ColumnChart(document.getElementById('chart_div'));
chart.draw(data, options);
});
$(window).resize(function(){
drawVisualization();
});
}
Regards.
there isn't a standard option, but you can use null for blank annotations
when loading, try the following to show annotations for every third row...
for (var i = 0; i< json[0].data.length; i++){
var annotation1 = null;
var annotation2 = null;
var annotation3 = null;
if ((i % 3) === 0) {
var annotation3 = json[3].data[i];
var annotation2 = json[2].data[i];
var annotation1 = json[1].data[i];
}
data.addRow([
json[0].data[i],
json[3].data[i],
annotation3,
json[2].data[i],
annotation2,
json[1].data[i],
annotation1
]);
}
I have a google visualisation linechart. I am having issues formatting the labels on the h-axis. I would like to have them rounded off to integers so it looks neater. I have looked at the documentation but could not find a solution. Here is my code:
HTML
<div id="myChart2" name="myChart2" width="500" height="280"></div>
jQuery
$(document).ready(function(){
var chartData = new google.visualization.DataTable();
chartData.addColumn('number', 'SPS');
chartData.addColumn('number', 'WGT');

You can add format:'#,###' to your hAxis object:
hAxis: {
format:'#,###',
title: 'SPS',
gridlines: {
count: 15
}
},
Here's an updated version of your fiddle: https://jsfiddle.net/w83mdx3y/3/
See customizing axes in the charts documentation for more information on how this works.
