How To Customize Google Chart With Hyperlink In The Label?
Solution 1:
first, recommend not usingjsapi
to load the library
according to the release notes...
The version of Google Charts that remains available via the jsapi loader is no longer being updated consistently. Please use the new gstatic loader from now on.
<scriptsrc="https://www.gstatic.com/charts/loader.js"></script>
this will only change the load
statement, to...
google.charts.load('current', {
callback: drawVisualization,
packages:['geochart']
});
(the callback
can be added to the load
statement as well)
next, according to the data format for regions mode,
the second column should be a number (not a string / link)
but since the link is needed for the click handler, use a DataView
to hide the column from the chart
^ this will fix the tooltip -- adding the name of the country instead of the link
the number column drives the shading of the country, according to the colorAxis
if no number is provided, as in the question, then colorAxis
will have no effect
last, there are no standard options to control the country border
see following working snippet...
google.charts.load('current', {
callback: drawVisualization,
packages:['geochart']
});
functiondrawVisualization() {
var data = google.visualization.arrayToDataTable([
['Country','Link',],
['Canada','http://www.google.ca'],
['Russia','http://www.bbc.com'],
['Australia','http://www.nytimes.com'],
]);
var view = new google.visualization.DataView(data);
view.hideColumns([1]);
var options = {
backgroundColor: '#81d4fa',
datalessRegionColor: '#f8bbd0',
defaultColor: 'black',
displayMode: 'regions',
tooltip: {textStyle: {color: '#FF0000'}, trigger:'focus',isHtml: true},
legend: 'none',
height:300,
width:400
};
var chart = new google.visualization.GeoChart(document.getElementById('visualization'));
google.visualization.events.addListener(chart, 'select', myClickHandler);
chart.draw(view, options);
functionmyClickHandler(){
var selection = chart.getSelection();
if (selection.length > 0) {
var link = data.getValue(selection[0].row, 1);
window.open(link, '_blank');
}
}
}
