Google chart vAxis title being cut off and needs to move closer to axis - google-visualization

Question

I'm trying to use Google charts to display the results of a survey. All seems fine, apart from the title of the vAxis is being cut off slightly and I can't work out how to move it closer to the axis.
This is the code:
google.load("visualization", "1.0", {packages:["bar"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Question title goes here', 'Percentage Score'],
['Always', 40],
['Usually', 30],
['Rarely', 10],
['Never', 20]
]);
var options = {
chart: {
title: 'Section Title',
subtitle: 'Section subtitle',
},
legend: { position: "none" },
vAxis: {
title: 'Percentage',
viewWindowMode:'explicit',
viewWindow: {
max:100,
min:0
}
},
bars: 'vertical', // Required for Material Bar Charts.
width: 600,
height: 500
};
var chart = new google.charts.Bar(document.getElementById('barchart_material'));
chart.draw(data, google.charts.Bar.convertOptions(options));
};
I have a fiddle here:

Answer 1

With a Core Chart, you can adjust the size of the chartArea to allow room for the title.
However, this doesn't appear to work for a Material Chart.
Also, I would recommend loading with loader.js vs. the older library jsapi.
See following example...
google.charts.load('current', {
callback: drawChart,
packages: ['bar', 'corechart']
});
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Question title goes here', 'Percentage Score'],
['Always', 40],
['Usually', 30],
['Rarely', 10],
['Never', 20]
]);
var options = {
chart: {
title: 'Section Title',
subtitle: 'Section subtitle',
},
chartArea: {
backgroundColor: 'cyan',
height: 400,
left: 60,
top: 20,
width: 500
},
legend: {
position: "none"
},
vAxis: {
title: 'Percentage',
viewWindowMode:'explicit',
viewWindow: {
max:100,
min:0
}
},
bars: 'vertical',
width: 600,
height: 500
};
var chart = new google.charts.Bar(document.getElementById('barchart_material'));
chart.draw(data, google.charts.Bar.convertOptions(options));
var chart2 = new google.visualization.ColumnChart(document.getElementById('barchart_core'));
chart2.draw(data, options);
};
<script src="https://www.gstatic.com/charts/loader.js"></script>
<div>========MATERIAL========</div>
<div id="barchart_material"></div>
<div>==========CORE==========</div>
<div id="barchart_core"></div>

I managed to find a real fiddle to the problem. I have updated the chart script so that the vAxis fontSize is 18:
google.load("visualization", "1.0", {packages:["bar"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['', 'Percentage'],
['Always', 40],
['Usually', 30],
['Rarely', 10],
['Never', 20]
]);
var options = {
chart: {
title: 'Company Performance'
},
legend: { position: "none" },
vAxis: {
title: 'Percentage',
titleTextStyle: {
fontSize: '18',
},
viewWindowMode:'explicit',
viewWindow: {
max:100,
min:0
}
},
bars: 'vertical', // Required for Material Bar Charts.
width: 400,
height: 400
};
var chart = new google.charts.Bar(document.getElementById('barchart_material'));
chart.draw(data, google.charts.Bar.convertOptions(options));
};
I have then added a CSS setting to force the font size back to normal:
#barchart_material g text {
font-size: 12px !important;
}
