I'm trying to show a custom tooltip on mouve over the bars, it show always the default tooltip.
I'm just trying to show a simple html code in the tooltip, so I can modify it after
What am I missing? thanks

see the data format for a timeline chart...
Column 0 - Row label
Column 1 - Bar label (optional)
Column 2 - Tooltip (optional)
Column 3 - Start
Column 4 - End
the issue stems from the view...
view.setColumns([0, 2, 3, 4, 5]);
so the chart thinks Column 2 is the Bar label
the issue can be corrected by swapping Column 2 with 3
view.setColumns([0, 3, 2, 4, 5]);

How can I get my google chart to resize properly, currently it gets bigger when I expand the window but it does not shrink when i shrink the window. Essentially I've wrapped the entire google chart in a resize function but it isn't quite right:
function resize() {
google.charts.load('current', {'packages':['timeline']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var container = document.getElementById('timeline');
var chart = new google.visualization.Timeline(container);
var dataTable = new google.visualization.DataTable();
dataTable.addColumn({ type: 'string', id: 'Type' });
dataTable.addColumn({ type: 'string', id: 'Organisation' });
dataTable.addColumn({ type: 'date', id: 'Start' });
dataTable.addColumn({ type: 'date', id: 'End' });
dataTable.addRows([
[ 'Work Experience', 'GE', new Date(2010, 8, 1 ), new Date(2011, 8, 30) ],
[ 'Work Experience', 'Shell', new Date(2015, 2, 1), new Date(2016, 1, 1) ],
[ 'Work Experience', 'British Gas', new Date(2016, 1, 1), new Date(2017, 9, 1) ],
[ 'Work Experience', 'British Telecom', new Date(2017, 9, 1), new Date() ],
[ 'Work Experience', 'University', new Date(2011, 8, 30), new Date(2015, 2,1) ]
]);
var options = {
timeline: {showRowLabels: false},
backgroundColor: '#161616',
barLabelStyle: { fontName: 'Roboto', color: '#ffffff' },
height: 100,
hAxis: {textStyle:{color: '#ffffff'}}
};
google.visualization.events.addListener(chart, 'ready', function () {
var labels = container.getElementsByTagName('text');
Array.prototype.forEach.call(labels, function(label) {
if (label.getAttribute('text-anchor') === 'middle') {
label.setAttribute('fill', '#ffffff');
}
});
});
google.visualization.events.addListener(chart, 'ready', function () {
var rects = container.getElementsByTagName('rect');
Array.prototype.forEach.call(rects, function(rect) {
// find chart <rect> element
if ((rect.getAttribute('x') === '0') && (rect.getAttribute('y') === '0')) {
// remove stroke from last <rect> element
rect.setAttribute('stroke', 'none');
rect.setAttribute('stroke-width', '0');
}
});
});
chart.draw(dataTable, options);
}
}
window.onload = resize;
window.onresize = resize;
when resizing, you need to clear the chart, before re-drawing.
if the chart is not cleared, it can prevent the chart's container from shrinking.
then when re-drawn, it is the same size.
(this all depends on the page layout, but clearing will resolve most issues)
use method --> chart.clearChart()
also, the load callback only needs to be called once per page load.
no need to include the load statement in the resize event handler.
and, google's load statement will wait for the page to load by default.
and can be used in place of --> window.onload
see following working snippet...
google.charts.load('current', {
packages: ['timeline']
}).then(function () {
var container = document.getElementById('timeline');
var chart = new google.visualization.Timeline(container);
var dataTable = new google.visualization.DataTable();
dataTable.addColumn({ type: 'string', id: 'Type' });
dataTable.addColumn({ type: 'string', id: 'Organisation' });
dataTable.addColumn({ type: 'date', id: 'Start' });
dataTable.addColumn({ type: 'date', id: 'End' });
dataTable.addRows([

['Work Experience', 'British Telecom', new Date(2017, 9, 1), new Date()],
['Work Experience', 'University', new Date(2011, 8, 30), new Date(2015, 2,1)]
]);
var options = {
timeline: {showRowLabels: false},
backgroundColor: '#161616',
barLabelStyle: {fontName: 'Roboto', color: '#ffffff'},

hAxis: {textStyle:{color: '#ffffff'}}
};
google.visualization.events.addListener(chart, 'ready', function () {
var labels = container.getElementsByTagName('text');
Array.prototype.forEach.call(labels, function(label) {
if (label.getAttribute('text-anchor') === 'middle') {
label.setAttribute('fill', '#ffffff');
}
});

// remove stroke from last <rect> element
rect.setAttribute('stroke', 'none');
rect.setAttribute('stroke-width', '0');
}
});
});
window.addEventListener('resize', drawChart);
drawChart();
function drawChart() {

<div id="timeline"></div>
I have a timeline chart made with Google charts, what I do is send a json with color values and other information, the size of the json is variable, what I want to do is that each row is painted with the color it has in the json, implement the following:
dataTable.addColumn({type: 'string', role: 'style'});
But it seems not to work, it gives me automatic colors.
The following is an image of my graph with the colors thrown by defautl, and not with the colors that I have in the json.
For example in this case, 'Production' has to be orange and 'Fusion' has to be purple.
This is my code:
function drawChart() {
$(".timeline").each(function () {
var obje = {{ devicejson|safe }};
var elem = $(this),
id = elem.attr('id');
var container = document.getElementById(id);
var chart = new google.visualization.Timeline(container);
var dataTable = new google.visualization.DataTable();
dataTable.addColumn({type: 'string', id: 'Role'});
dataTable.addColumn({type: 'string', id: 'Name'});
dataTable.addColumn({type: 'date', id: 'Start'});
dataTable.addColumn({type: 'date', id: 'End'});
dataTable.addColumn({type: 'string', id: 'TimeEst'});
dataTable.addColumn({type: 'string', role: 'style'});
for (n = 0; n < obje.length; ++n) {
if (obje[n].device_id == id) {
dataTable.addRows([
['Department', obje[n].digitaloutput_user_description, new Date('"' + obje[n].startdatetime + '"'), new Date('"' + obje[n].enddatetime + '"'), obje[n].lighstate_user_description, obje[n].color],
]);
var options = {
tooltip: {isHtml: true},
timeline: {
showRowLabels: false,
},
avoidOverlappingGridLines: false,
{#hAxis: {format: 'dd-MMM-yyyy HH:mm:ss'}#}
};
}
}
for (n = 0; n < obje.length; ++n) {
if (obje[n].device_id == id) {
console.log(obje[n].color)
}
}
var formatTime = new google.visualization.DateFormat({
pattern: 'yyyy-MM-dd HH:mm:ss a'
});
var view = new google.visualization.DataView(dataTable);
view.setColumns([0, 1, {
role: 'tooltip',
type: 'string',
calc: function (dt, row) {
// build tooltip
var dateBegin = dt.getValue(row, 2);
var dateEnd = dt.getValue(row, 3);
var oneHour = (60 * 1000);
var duration = (dateEnd.getTime() - dateBegin.getTime()) / oneHour;
var tooltip = '<div><div class="ggl-tooltip"><span>';
tooltip += dt.getValue(row, 0) + ':</span> ' + dt.getValue(row, 1) + '</div>';
tooltip += '<div class="ggl-tooltip"><div>' + formatTime.formatValue(dateBegin) + ' - ';
tooltip += formatTime.formatValue(dateEnd) + '</div>';
tooltip += '<div><span>Duration: </span>' + duration.toFixed(0) + ' minutes</div>';
tooltip += '<div><span>Estate: </span>' + dt.getValue(row, 5) + '</div></div>';
return tooltip;
},
p: {html: true}
}, 2, 3]);
google.visualization.events.addListener(chart, 'ready', function () {
var labels = container.getElementsByTagName('text');
Array.prototype.forEach.call(labels, function (label) {
label.setAttribute('font-weight', 'normal');
});
});
chart.draw(view.toDataTable(), options);
})
}
on the timeline chart, the style role will only work when used as the third column (column index 2).
see following working snippet...
google.charts.load('current', {
'packages': ['timeline']
});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var container = document.getElementById('timeline');
var chart = new google.visualization.Timeline(container);
var dataTable = new google.visualization.DataTable();
dataTable.addColumn({
type: 'string',
id: 'President'
});
dataTable.addColumn({
type: 'string',
id: 'Bar'
});
dataTable.addColumn({ // <-- add style role here...
type: 'string',
role: 'style'
});
dataTable.addColumn({
type: 'date',
id: 'Start'
});
dataTable.addColumn({
type: 'date',
id: 'End'
});
dataTable.addRows([
['Washington', 'test1', 'cyan', new Date(1789, 3, 30), new Date(1797, 2, 4)],
['Adams', 'test2', 'magenta', new Date(1797, 2, 4), new Date(1801, 2, 4)],
['Jefferson', 'test3', 'lime', new Date(1801, 2, 4), new Date(1809, 2, 4)]
]);

Someone can help me? Many thanks!!!
no config option exists,
but we can manually change the chart's svg,
on the chart's 'ready' event.
here, we find the chart <rect> element,
and remove the stroke...
google.visualization.events.addListener(chart, 'ready', function () {
var rects = container.getElementsByTagName('rect');
Array.prototype.forEach.call(rects, function(rect) {
// find chart <rect> element
if ((rect.getAttribute('x') === '0') && (rect.getAttribute('y') === '0')) {
// remove stroke from last <rect> element
rect.setAttribute('stroke', 'none');
rect.setAttribute('stroke-width', '0');
}
});
});
see following working snippet...
google.charts.load('current', {
packages:['timeline']
}).then(drawChart);
function drawChart() {
var container = document.getElementById('example5.4');
var chart = new google.visualization.Timeline(container);
var dataTable = new google.visualization.DataTable();
dataTable.addColumn({ type: 'string', id: 'Role' });
dataTable.addColumn({ type: 'string', id: 'Name' });
dataTable.addColumn({ type: 'date', id: 'Start' });
dataTable.addColumn({ type: 'date', id: 'End' });
dataTable.addRows([

I'm attempting to change the stroke color for columns in the Google Visualization Timeline.
I am able to do that but I can't specify that only the vertical stroke lines should be changed not the horizontal lines.
Is there a way to identify just the vertical lines? The svg calls both horizontal lines and vertical "path d".
google.charts.load('current', {

Here's one way: Take the X coordinate from the d attribute (the first digit after M and the first digit after L) if they are the same, it is a vertical line.
Regex Answer
Using regex to match the first numbers after M to the numbers after L: M(\d+).*L\1
google.charts.load('current', {
callback: drawChart,
packages: ['timeline']
});
function drawChart() {
var container = document.getElementById('timeline');
var chart = new google.visualization.Timeline(container);
var dataTable = new google.visualization.DataTable();
dataTable.addColumn({ type: 'string', id: 'President' });
dataTable.addColumn({ type: 'date', id: 'Start' });
dataTable.addColumn({ type: 'date', id: 'End' });
dataTable.addRows([
[ 'Washington', new Date(1789, 3, 30), new Date(1797, 2, 4) ],
[ 'Adams', new Date(1797, 2, 4), new Date(1801, 2, 4) ],

]);
var observer = new MutationObserver(setcolumnstroke);
google.visualization.events.addListener(chart, 'ready', function () {
setcolumnstroke();
observer.observe(container, {
childList: true,
subtree: true
});
});
function setcolumnstroke() {
Array.prototype.forEach.call(container.getElementsByTagName('path'), function (path) {
// Check for vertical lines
if ( path.getAttribute('d').match(/M(\d+).*L\1/) ) {
path.setAttribute('stroke', '#FF0000');
} else {
path.setAttribute('stroke', '#000000');
}
});
}
chart.draw(dataTable);

Old Answer:
Using substring method: if (d.substring(1, 4) == d.substring(d.indexOf('L')+1, d.indexOf('L')+4))
// The X coordinate of the M (move) command
d.substring(1, 4)
// The X coordinate of the L (line) command
d.substring(d.indexOf('L')+1, d.indexOf('L')+4))
Note this would break if it is not formatted exactly as M...L... but perhaps google charts path output is always in that format.
google.charts.load('current', {
callback: drawChart,
packages: ['timeline']
});
function drawChart() {
var container = document.getElementById('timeline');
var chart = new google.visualization.Timeline(container);

I would like to ask if it is possible that the haxis value (The one with dates below) for Google Timeline change to string format?
For example, Oct. 30 will be changed to Week 1, Nov. 6 to Week 2, and so on.
Any help and suggestions are welcomed and appreciated.
Thanks in advance!
the timeline chart is very limited compared to the core charts
both in terms of options available and helper methods for finding chart coordinates, etc...
but like core charts, timelines produce svg, which can be modified using javascript
see following working snippet...
once the chart's 'ready' event fires, all of the haxis labels are removed
then custom labels are added back for the week numbers
before removing all the labels, one is cloned, in order to keep the same font, color, y-coordinate, etc...
then the timeline bars are used to find the x-coordinate and add the new label
