Google visualization dual Y axis chart align line with specific bar - javascript

I have attached snippet for a dual Y axis chart.
The orange dot for Ontime% Goal corresponds with the blue bar for Ontime %. Both have been assigned to targetAxisIndex: 0
Can I shift/move the dot to align above the blue bar? (see attached picture for desired position).
Thank you as always to the experts out there!
google.charts.load('current', {'packages':['corechart', 'bar']});
google.charts.setOnLoadCallback(drawStuff);
function drawStuff() {
var button = document.getElementById('change-chart');
var chartDiv = document.getElementById('chart_div');
var data = google.visualization.arrayToDataTable([
['Type', 'Ontime%', 'Count', 'Ontime% Goal'],
['AE', 90, 500, 100]
]);
var classicOptions = {
width: 900,
series: {
0: {targetAxisIndex: 0, type: 'bars'},
1: {targetAxisIndex: 1, type: 'bars'},
2: {targetAxisIndex: 0, type: 'line', pointSize: 8, pointShape: { type: 'circle' } },

nothing out of the box will allow you to adjust the position of the point.
you can move it manually, on the chart's ready event.
but the chart will move it back when the user hovers the point.
you can use a MutationObserver to move the point when the chart moves it back,
but this will just cause it to blink from one spot to the other while it is being hovered.
not much you can do, unless you disable tooltips.
see following working snippet,
hover the point to see it move...
google.charts.load('current', {
packages: ['corechart']
}).then(function () {
//var button = document.getElementById('change-chart');
var chartDiv = document.getElementById('chart_div');
var data = google.visualization.arrayToDataTable([
['Type', 'Ontime%', 'Count', 'Ontime% Goal'],
['AE', 90, 500, 100]
]);
var classicOptions = {
width: 900,
series: {
0: {targetAxisIndex: 0, type: 'bars'},
1: {targetAxisIndex: 1, type: 'bars'},
2: {
targetAxisIndex: 0,
type: 'line',
pointSize: 8,
pointShape: {type: 'circle'},
},
},
title: 'Ontime % on the left, Count on the right',
bar:{
width: "60%"
},
vAxis: {
minValue: 0
},
vAxes: {
0: {title: 'Ontime %'},
1: {title: 'Count'}
}
};
function drawClassicChart() {
var classicChart = new google.visualization.ColumnChart(chartDiv);
google.visualization.events.addListener(classicChart, 'ready', function () {
var chartLayout = classicChart.getChartLayoutInterface();
var bounds = chartLayout.getBoundingBox('bar#0#0');
var observer = new MutationObserver(function () {
var circles = chartDiv.getElementsByTagName('circle');
if (circles.length > 1) {
circles[1].setAttribute('cx', (bounds.left + (bounds.width / 2)));
}
});
observer.observe(chartDiv, {
childList: true,
subtree: true
});
});
classicChart.draw(data, classicOptions);
//button.innerText = 'Change to Material';
//button.onclick = drawMaterialChart;
}
drawClassicChart();
});
<script src="https://www.gstatic.com/charts/loader.js"></script>
<div id="chart_div"></div>
best case, you could disable the chart's tooltips,
then add your own custom tooltips,
for both the point and columns, etc...
the chart does provide mouseover and mouseout events,
not sure its worth the effort...

Labels on google charts are not visible in specific coonfiguration

I have chart configured like in working jsfiddle.
I have configured labels(basing on google doc documentation: https://developers.google.com/chart/interactive/docs/gallery/barchart#labeling-bars)
But they aren't visible. When I change chart type to google.visualization.BarChart, then labels appear but bars structure is destroyed. How to add labels to my configuration?
Replicated:
https://jsfiddle.net/41fmq37j/
JS:
google.charts.load('current', {'packages':['corechart', 'bar']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
[{label: 'Year', id: 'year', type: 'number'},
{label: 'Sales', id: 'Sales', type: 'number'},
{label: 'Expenses', id: 'Expenses', type: 'number'},
{ role: 'annotation' }],
[2014, 10, 400 ,'label1'],
[2014, 800, 100 ,'label2'],
[2015, 200, 460 ,'label3'],
[2015, 110, 660 ,'label4'],
[2016, 100, 300 ,'label5'],
[2016, 600, 120 ,'label6'],
[2017, 360, 540 ,'label7'],
[2017, 300, 500 ,'label8']
]);
var options = {
chart: {
title: 'Sales and Expenses',
subtitle: 'Some descr',
},
bars: 'horizontal',
height: 400,
isStacked: true,
};
var chart = new google.charts.Bar(document.getElementById('chart_div'));
chart.draw(data, google.charts.Bar.convertOptions(options));
}
HTML:
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<div id="chart_div"></div>
EDIT:
It is possible to configure yAxis like below? Because current format can be confusing.
I would like to create more, a little different graphs, for example which will group bars by string. So another question is: how we can archive grouping yAxis by string? Maybe we should create any comparator?
material charts do not support columns roles, such as 'annotation',
along with several other options
and, it's not possible to have multiple stacks per label in classic charts
as such, we can use a material chart,
and add our own annotations manually,
on the chart's 'ready' event
see following working snippet...
google.charts.load('current', {
packages:['bar']
}).then(function () {
var data = google.visualization.arrayToDataTable([

EDIT
the annotation script finds the first y-axis label,
and uses it as a clone for the annotations.
if the values for the y-axis change,
then the script to find the label needs to change.
updated here...
// find label to clone
labels = svg.getElementsByTagName('text');

Want to add top padding on annotation text in bar chart in Google Chart (Visualization)

I am using Google Chart's bar graph chart. There are annotation for every bar at the top, inside of the bar and I want create more space (more than default) between bar top line and annotation text. I have not find any way to create top padding (or top margin) around annotation text.
Here is my code:
var data = google.visualization.arrayToDataTable([
[USER_AVERAGE, 'User Average', { role: 'style' }],
['SANDRA COOMBS', 8.6, '#008FBE'],
['STEVE ADAMS', 4.3, '#008FBE'],
]);
var view = new google.visualization.DataView(data);
view.setColumns([0, 1, 2,
{
calc: "stringify",
sourceColumn: 1,
type: "string",
role: "annotation"
}]);
var options = {
legend: {
position: 'none'
},
chartArea: { width: width, height: height, right: right },
isStacked: true,
orientation: orientation.orientation,
fontSize: '12',
fontName: 'OpenSans-Regular',
hAxis: {
viewWindowMode: 'maximized',
},
vAxis: {
viewWindowMode: 'maximized',
},
animation: {
startup: true,
duration: 1500,
easing: 'out',
},
};
var chart = new google.visualization.ColumnChart(document.getElementById("averageDaysChart"));
chart.draw(view.toDataTable(), options);
there are no config options for annotation padding, position, or the like...
however, you can move them manually on the chart's 'animationfinish' event
but, a MutationObserver must be used,
because the chart will move them back on interactivity,
such as when you hover the column.
see following working snippet for an example of moving the annotations...
google.charts.load('current', {
packages: ['corechart']
}).then(function () {
var data = google.visualization.arrayToDataTable([
['USER_AVERAGE', 'User Average', { role: 'style' }],
['SANDRA COOMBS', 8.6, '#008FBE'],
['STEVE ADAMS', 4.3, '#008FBE'],
]);
var view = new google.visualization.DataView(data);
view.setColumns([0, 1, 2,
{
calc: "stringify",
sourceColumn: 1,
type: "string",
role: "annotation"
}]);
var options = {
legend: {
position: 'none'
},
//chartArea: { width: width, height: height, right: right },
isStacked: true,
//orientation: orientation.orientation,
fontSize: '12',
fontName: 'OpenSans-Regular',
hAxis: {
viewWindowMode: 'maximized',
},
vAxis: {
viewWindowMode: 'maximized',
},
animation: {
startup: true,
duration: 1500,
easing: 'out',
},
};
var container = document.getElementById("averageDaysChart");
var chart = new google.visualization.ColumnChart(container);
google.visualization.events.addListener(chart, 'animationfinish', function () {
moveAnnotations();
var observer = new MutationObserver(moveAnnotations);
observer.observe(container, {
childList: true,
subtree: true
});
});
var originalY = {};
function moveAnnotations() {
var labels = container.getElementsByTagName('text');
Array.prototype.forEach.call(labels, function(label) {
if ((!isNaN(parseFloat(label.textContent))) && (label.getAttribute('text-anchor') === 'middle')) {
if (!originalY.hasOwnProperty(label.textContent)) {
originalY[label.textContent] = parseFloat(label.getAttribute('y'));
}
label.setAttribute('y', originalY[label.textContent] + 20);
}
});
}
chart.draw(view.toDataTable(), options);
});
<script src="https://www.gstatic.com/charts/loader.js"></script>
<div id="averageDaysChart"></div>
No need for an animation hook or MutationObserver, just use good old fashioned CSS for this.
With Column and Bar charts, you only want to apply the "padding" to the annotation if it's placed within the bar itself. It's only placed inside the bar if the annotation text fits in the bar. When placed inside, it's given a white text color, so let's target that.
#averageDaysChart text[fill="#ffffff"] {
transform: translateY(10px);
}

Javascript charts as input

I have a requirement as below.
I need to input time series data (day data) using a graph. The data is usually like below but the profile can be changed depending upon the situation.
Right now the data is being manually entered in textboxes which makes it very difficult.
I am wondering whether there are solutions that let user draw on a chart and generate the data in the back. In other words, the user picks certain points and the profile is drawn.
see following working snippet, click on the chart to add a data point...
google.charts.load('current', {
callback: function () {
var data = new google.visualization.DataTable({
"cols": [
{"label": "x", "type": "number"},
{"label": "y", "type": "number"}
]
});
var axisMax = 10;
var ticks = [];
for (var i = 0; i <= axisMax; i = i + 0.5) {
ticks.push(i);
}
var options = {
chartArea: {
bottom: 64,
height: '100%',
left: 64,
top: 24,
width: '100%'
},
hAxis: {
format: '0.0',
textStyle: {
fontSize: 9
},
ticks: ticks,
title: data.getColumnLabel(0),
viewWindow: {
min: 0,
max: axisMax
}
},
height: 600,
legend: {
position: 'top'
},
pointSize: 4,
vAxis: {
format: '0.0',
textStyle: {
fontSize: 9
},
ticks: ticks,
title: data.getColumnLabel(1),
viewWindow: {
min: 0,
max: axisMax
}
}
};
var tableDiv = document.getElementById('table_div');
var table = new google.visualization.Table(tableDiv);
var chartDiv = document.getElementById('chart_div');
var chart = new google.visualization.LineChart(chartDiv);
var chartLayout = null;
google.visualization.events.addListener(chart, 'ready', function () {
chartLayout = chart.getChartLayoutInterface();
});
google.visualization.events.addListener(chart, 'click', function (sender) {
data.addRow([
chartLayout.getHAxisValue(sender.x),
chartLayout.getVAxisValue(sender.y)
]);
drawChart();
});
function drawChart() {
chart.draw(data, options);

Google chart show dual axis represent same data

I wanted to make a google chart which shows the dual y axis , but both should represents the same bar.
See this fiddle
google.charts.load('current', {'packages':['bar']});
google.charts.setOnLoadCallback(drawStuff);
function drawStuff() {
var data = new google.visualization.arrayToDataTable([
['Car', 'Distance travelled'],
["mercedes", 44],
["lamborgh", 31],
["porsche", 12],
["aston martin", 10]
]);
var options = {
title: 'Car distance',
width: 500,
legend: { position: 'none' },
chart: { subtitle: 'money spent in distance travelled' },
axes: {
x: {
0: { side: 'top', label: 'Car stats'} // Top x-axis.
}
},
bar: { groupWidth: "20%" }
};
var chart = new google.charts.Bar(document.getElementById('top_x_div'));
// Convert the Classic options to Material options.
chart.draw(data, google.charts.Bar.convertOptions(options));
};
I have shown the Cars distance traveled , thats actually in kms, now i wanted to show the cars money spent in fuel
like a car traveled 1km and it spends $2 in fuel
now looking at the fiddle suppose we have mercedes car traveled 44km then it costs around $88 which should be depicted by the 2nd y-axis
How it can be done?
each series (y-value) in the chart represents a column in the data
"series 0" = column 1 in the data
"series 1" = column 2 in the data
then use the options to map each series to an axis...
series: {
0: { axis: 'distance' },
1: { axis: 'fuel' }
},
axes: {
y: {
distance: {label: 'Distance'},
fuel: {side: 'right', label: 'Fuel'}
}
}
see following working snippet...
google.charts.load('current', {
callback: drawChart,
packages:['bar']
});
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Car', 'Distance travelled', 'Fuel'],
['mercedes', 44, 88],
['lamborgh', 31, 62],
['porsche', 12, 24],
['aston martin', 10, 20]
]);
var options = {
title: 'Car distance',
height: 500,
legend: { position: 'none' },
chart: { subtitle: 'money spent in distance travelled' },
bar: { groupWidth: "20%" },
series: {
0: { axis: 'distance' },
1: { axis: 'fuel' }
},
axes: {
x: {
0: { side: 'top', label: 'Car stats'} // Top x-axis.
},
y: {
distance: {label: 'Distance'},
fuel: {side: 'right', label: 'Fuel'}
}
}
};
var chart = new google.charts.Bar(document.getElementById('chart_div'));
chart.draw(data, options);
};
<script src="https://www.gstatic.com/charts/loader.js"></script>
<div id="chart_div"></div>
EDIT
to remove the second bar but keep the axis requires a bit of manipulation
and use of options not available to material charts
see following working snippet using a core chart...
google.charts.load('current', {
callback: drawChart,
packages:['bar', 'corechart']
});
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Car', 'Distance travelled'],
['mercedes', 44],
['lamborgh', 31],
['porsche', 12],
['aston martin', 10]
]);
var view = new google.visualization.DataView(data);
view.setColumns([0, 1, {
label: 'Fuel',
type: 'number',
calc: function () {
return null;
}
}]);
var options = {
title: 'Car distance',
height: 500,
legend: { position: 'none' },
chart: { subtitle: 'money spent in distance travelled' },
bar: { groupWidth: "20%" },
// center bar with x-axis label
isStacked: true,
// material chart theme
theme: 'material',
// y-axis settings
vAxes: {
0: {
ticks: [0, 10, 20, 30, 40, 50],
title: 'Distance'
},
1: {
ticks: [0, 20, 40, 60, 80, 100],
title: 'Fuel'
}
},
// map series
series: {
0: {
targetAxisIndex: 0
},
1: {
targetAxisIndex: 1
}
}
};
var chart = new google.visualization.ColumnChart(document.getElementById('chart_div'));
chart.draw(view, options);
};
<script src="https://www.gstatic.com/charts/loader.js"></script>
<div id="chart_div"></div>
note
material charts --> packages:['bar'] -- google.charts.Bar
core charts --> packages:['corechart'] -- google.visualization.ColumnChart

Is it possible to have different legend background colors for different data rows in Google bar chart, without breaking the chart?

See the example code:
var data = new google.visualization.DataTable();
data.addColumn('string', 'Mac');
data.addColumn('number', 'Score');
data.addColumn({ type: 'string', role: 'style' });
data.addRows([
['Mac model 12', 200, 'color: #8bba30; opacity: 0.75;'],
['Another Mac Model', 110, 'color: #ffcc33; opacity: 0.75;'],
]);
var options = {
title: '',
width: 500,
height: data.getNumberOfRows() * 40 + 100,
hAxis: {
minValue: 0,
maxValue: 255,
ticks: [0, 75, 150, 255],
textPosition: 'out',
side: 'top'
},
series: {
0: { axis: 'Mac' },
1: { axis: 'Score' }
},
chartArea: {
top: 0,
bottom: 50,
right: 50,
left: 150
},
legend: { position: 'none' },
fontSize: 12,
bar: {groupWidth: '75%'},
};
var chart = new google.visualization.BarChart(document.getElementById('apple_div'));
chart.draw(data, options);
}
This is the output:
See, there are different colors for different bars. But I want different color and/or background-color for different legends on left side.
Can someone help me with this please?
I found following answer, Is it possible to show each legend in different color in google pie chart.
But it suggests on breaking down the chart(i.e. to draw separate charts for each rows), which is not desirable as there are large numbers of rows.
Not sure what you mean by breaking the chart, but...
You can modify the chart svg, once the 'ready' event fires.
This example changes the color of the legend text to match the bar color.
google.charts.load('current', {
callback: drawChart,
packages: ['corechart']
});
function drawChart() {
var colors = ['#8bba30', '#ffcc33'];
var data = new google.visualization.DataTable();
data.addColumn('string', 'Mac');
data.addColumn('number', 'Score');
data.addColumn({ type: 'string', role: 'style' });
data.addRows([
['Mac model 12', 200, 'color: ' + colors[0] + '; opacity: 0.75;'],
['Another Mac Model', 110, 'color: ' + colors[1] + '; opacity: 0.75;'],
]);
var options = {
title: '',
width: 500,
height: data.getNumberOfRows() * 40 + 100,
hAxis: {
minValue: 0,
maxValue: 255,
ticks: [0, 75, 150, 255],
textPosition: 'out',
side: 'top'
},
series: {
0: { axis: 'Mac' },
1: { axis: 'Score' }
},
chartArea: {
top: 0,
bottom: 50,
right: 50,
left: 150
},
legend: { position: 'none' },
fontSize: 12,
bar: {groupWidth: '75%'},
};
var chartContainer = document.getElementById('apple_div');
var chart = new google.visualization.BarChart(chartContainer);
google.visualization.events.addListener(chart, 'ready', function () {
var labels = chartContainer.getElementsByTagName('text');
var colorIndex = 0;
for (var i = 0; i < labels.length; i++) {
if (labels[i].getAttribute('text-anchor') === 'end') {
labels[i].setAttribute('fill', colors[colorIndex]);
colorIndex++;
}
}
});
chart.draw(data, options);
}
<script src="https://www.gstatic.com/charts/loader.js"></script>
