Dual Axis Stacked Column Chart - charts

I'm trying to create a dual axis stacked column Chart using Google's Classic Charts.
just like the Google's Material charts.
but there seems in classic one, the new stacks gets render over the previous one.
check the code below: Switch in between classic and material, you will find the difference.
Why classic? As it support tooltip modification unlike Material Chart.
Is it possible to have all stacks adjacent to the previous stack in classic chart?
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([
['Galaxy', 'Distance', 'Brightness', 'Contrast', {
type: 'string',
role: 'tooltip',
'p': {
'html': true
}
}],
['Canis Major Dwarf', 8000, 23.3, 2.8, 'Irregular galaxy'],
['Sagittarius Dwarf', 24000, 3.5, 6.6, '5,000 ly'],
['Ursa Major II Dwarf', 30000, 14.3, 10.67, 'Half-light radius'],
['Lg. Magellanic Cloud', 50000, 0.9, 3.6, null],
['Bootes I', 60000, 13.1, 10.23, null]
]);
var materialOptions = {
width: 900,
isStacked: true,
chart: {
title: 'Nearby galaxies',
subtitle: 'distance on the left, brightness on the right'
},
series: {
0: {
axis: 'distance'
}, // Bind series 0 to an axis named 'distance'.
1: {
axis: 'brightness'
}, // Bind series 1 to an axis named 'brightness'.
2: {
axis: 'brightness'
} // Bind series 1 to an axis named 'brightness'.
},
axes: {
y: {
distance: {
label: 'parsecs'
}, // Left y-axis.
brightness: {
side: 'right',
label: 'apparent magnitude'
} // Right y-axis.
}
}
};
var classicOptions = {

isStacked: true,
series: {
0: {
targetAxisIndex: 0
},
1: {
targetAxisIndex: 1

2: {

vAxes: {
// Adds titles to each axis.
0: {
title: 'parsecs'
},
1: {
title: 'apparent magnitude'
}
}
};
function drawMaterialChart() {
var materialChart = new google.charts.Bar(chartDiv);
materialChart.draw(data, google.charts.Bar.convertOptions(materialOptions));
button.innerText = 'Change to Classic';
button.onclick = drawClassicChart;
}
function drawClassicChart() {
var classicChart = new google.visualization.ColumnChart(chartDiv);
classicChart.draw(data, classicOptions);
button.innerText = 'Change to Material';
button.onclick = drawMaterialChart;
}
drawMaterialChart();

Google Charts Bar Chart avoid overlappin annotations [duplicate]

I'm creating a stacked bar graph and need to show the label inside the stack. But Few of the label's are getting overlapped. for reference image
Can you please help me how to avoid overlapping using google charts ?

Regards,
Srikanth

first, it appears you have an extra annotation column in your data,
that doesn't appear to belong to a specific column
copied from question above...
var data = new google.visualization.arrayToDataTable([
[
'Time Period',
'XYZ',
{role: 'annotation'},
'ABC',
{role: 'annotation'},
{role: 'annotation'}, // <-- extra annotation?
'Average'
],
[
'Aug',
3754,
'3754',
2089,
'2089',
'5,843', // <-- extra annotation?
4000
],
...
]);
this could be part of the reason it's so cluttered
regardless, use the annotations configuration option for adjustments
the config option can be used for the entire chart, or just for a specific series
var options = {
// entire chart
annotations: {
textStyle: {
fontSize: 10
}
},
series: {
0: {
// series 0
annotations: {
stem: {
length: 0
},
},
},
1: {
// series 1
annotations: {
stem: {
length: 16
}
},
},
}
...
};
specifically, you can use a combination of annotations.textStyle.fontSize and annotations.stem.length to prevent overlapping
see following working snippet...
annotations.textStyle.fontSize is reduced for the entire chart
this allows the first annotation on the second column to fit within the bar
annotations.stem.length is set to zero (0) on the first series,
and 16 on the second...
(the extra annotation from the question has been removed)
google.charts.load('current', {
callback: drawStacked,
packages: ['corechart']
});
function drawStacked() {
var data = new google.visualization.arrayToDataTable([
['Time Period', 'XYZ', {role: 'annotation'}, 'ABC', {role: 'annotation'}, 'Average'],
['Aug', 3754, '3754', 2089, '2089', 4000],
['Sept', 900, '900', 200, '200', 4000],
['Oct', 2000, '2000', 4900, '4900', 4000],
['Nov', 1700, '1700', 2200, '2200', 4000],
['Dec', 2400, '2400', 2089, '2200', 4000]
]);
var options = {
annotations: {
textStyle: {
fontSize: 10
}
},
series: {
0: {
annotations: {
stem: {
length: 0
},
},
},
1: {
annotations: {
stem: {
length: 16
}
},
},
2: {
type: 'line'
}
},
hAxis: {
title: 'Time Period'
},
isStacked: true,
seriesType: 'bars',
title: 'Overview of the Tickets',
vAxis: {
title: 'Number of Tickets'
}
};
var chart = new google.visualization.ComboChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
<script src="https://www.gstatic.com/charts/loader.js"></script>
<div id="chart_div"></div>
EDIT
since the third annotation is needed as the total of the other two stacks,
recommend adding the series value for the total, in addition to the annotation column
and setting the total series type to 'line'
this will place the total annotation above the rest, for sure
so long as there is enough room on the chart to display the annotation above the bars
to ensure enough room above bars, find the max vAxis value, and add a value that will create enough room for the annotation
then set that value as vAxis.viewWindow.max
you can turn off the line and point, and hide the total series from the legend if needed
in my experience, it takes quite a bit of manipulation to get a complex google chart to display nicely
see the following working snippet, which incorporates the third, 'total', annotation...
google.charts.load('current', {
callback: drawStacked,
packages: ['corechart']
});
function drawStacked() {
var data = new google.visualization.arrayToDataTable([
['Time Period', 'XYZ', {role: 'annotation'}, 'ABC', {role: 'annotation'}, 'TOTAL', {role: 'annotation'}, 'Average'],

['Oct', 2000, '2,000', 4900, '4,900', 6900, '6,900', 4000],
['Nov', 1700, '1,700', 2200, '2,200', 3900, '3,900', 4000],
['Dec', 2400, '2,400', 2089, '2,089', 4489, '4,489', 4000]
]);
// find max for all columns to set top vAxis number
var maxVaxis = 0;
for (var i = 1; i < data.getNumberOfColumns(); i++) {
if (data.getColumnType(i) === 'number') {
maxVaxis = Math.max(maxVaxis, data.getColumnRange(i).max);
}
}
var options = {

I think it happens because there's not enough vertical space for the labels.
Try this:
Save the highest value of the graph (let's call it maxNumber)
In the "options" set vAxis maxValue to be maxNumber plus a little more.
I have 4 horizontal lines in my graph so I wrote:
var options = {
title: chartTitle,
....... //Your options
vAxis: {
//Add more space in order to make sure the annotations are not overlapping
maxValue: maxNumber + maxNumber/4,
},

Google Chart - Bar Series Title Different Color

I have a chart which has 4 series (Fiddle link below). Currently, it has Title1, Title2, Title3, and Title4. I want to change the different color for each title text name (Not the bar); for example, Title1 is red, Title2 is blue, Title3 is green, and Title4 is black. Is there a way to change all these titles with different colors?

Google Bar chart bars & axis do not correlate to data

https://i.imgur.com/qKcSRjS.png
The values of the bars, from top to bottom, are 66, 77, 91, 0
As you can see, the labels on the X axis are not to scale and seem to simply indicate the value of each bar, and the bars are also not scaled to their value they seem to simply stack in a staircase fashion. The bottom bar should be 'empty' as it is 0.
The data is dynamically generated but here is the resulting code:
function drawRightY() {
var data = google.visualization.arrayToDataTable([ ['Date', 'Received'], ['1/15/2018', '66'],['1/22/2018', '77'],['1/29/2018', '91'],['2/5/2018', '0'] ]);
var materialOptions = {
chart: {
hAxis: {
title: 'Date',
minValue: 0,
scaleType: 'log'
},
vAxis: {
title: 'Received'
},
bars: 'horizontal',
legend: {
position: 'none'
},
axes: {
y: {
0: { side: 'left' }
}
}
};

the values in the data should be numbers, not strings (remove single quotes)
['1/15/2018', '66'] // <-- string
['1/15/2018', 66] // <-- number
see following working snippet...
google.charts.load('current', {
packages:['corechart']
}).then(function () {
var data = google.visualization.arrayToDataTable([ ['Date', 'Received'], ['1/15/2018', 66],['1/22/2018', 77],['1/29/2018', 91],['2/5/2018', 0] ]);

ChartJS - ignore labels

I am using ChartJS and need a chart like this: https://tppr.me/OE08p
Meaning it should ignore 4 of the labels (flexibility, external, stability, internal) and connect the dots from the other 4 labels (like the red lines show on the screenshot).
Can I ignore these 4 labels data-wise somehow, but keep them?
Other chart packages/solutions are welcome, if it is not possible in chartjs.

You can use highchart.js library, see:
docs: https://www.highcharts.com/docs/chart-and-series-types/polar-chart
example: https://www.highcharts.com/demo/polar-spider
with these options:
plotOptions: {
series: {
connectNulls: true
}
}
and filtering data with map function like below (just for example):
data.map(filter)
<omissis>
function filter(item, index) {
if (index==2)
return null;
else
return item;
}
here is a jsfiddle showing this approach: http://jsfiddle.net/beaver71/w6ozog1c/

// original data
var data1 = [43000, 19000, 60000, 35000, 17000, 10000],

Google Visualization API -- Putting Y Axis on Right Side?

Using: http://code.google.com/apis/chart/interactive/docs/gallery/linechart.html#Loading
There isn't any options to put the y axis on the right side of the chart? For reals?! :P
Anyone know how to do such a 'radical' thing? The charting API lets you do this, but not the visualization?
Thanks SO.

You can get around this via the series option, and specifying a dummy data series for series[0]. Like so:
<script type="text/javascript" src="http://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load('visualization', '1', {packages: ['corechart']});

var data = new google.visualization.DataTable();
data.addColumn('string', 'xAxis');
data.addColumn('number', 'dummySeries');
data.addColumn('number', 'realSeries');
data.addRow(['x label', null, 2]); // dummy series value needs to be null, otherwise if interactivity is on, the user can discover the dummy values even if the line is hidden per below
data.addRow(...iterate & add the rest of your data);
new google.visualization.LineChart(document.getElementById('graphdiv')).
draw(data, {curveType: 'function',
series:[{lineWidth:0},{targetAxisIndex:1}]} // specify right y-axis for 2nd series, and 'hide' the line for the 1st series as a precaution with lineWidth
);
}
google.setOnLoadCallback(drawVisualization);
</script>

function singleUserChart() {
google.charts.load('current', { packages: ['corechart', 'bar'] });
google.charts.setOnLoadCallback(drawAnnotations);
function drawAnnotations() {
var dataPercentage = new google.visualization.DataTable();
dataPercentage.addColumn('string', 'Productivity');
dataPercentage.addColumn('number', 'Ravi');
dataPercentage.addColumn({ type: 'string', role: 'annotation' });
dataPercentage.addColumn('number', 'Avg Data');
dataPercentage.addColumn({ type: 'string', role: 'annotation' });
dataPercentage.addRows([
['%Score1', 12, '12%', 15, '15%'],
['%Score2', 25, '25%', 21, '21%']
]);
singleUserChartOptions(dataPercentage, 'individualUserPercentageChart', true, 450);
}
