1. Přidejte prvek <div> (s jedinečným ID) do kódu HTML, kam chcete graf zobrazit:
<div id="myChart" style="max-width:700px; height:400px"></div>2. Přidat odkaz na načítání grafů:
<script src="https://www.gstatic.com/charts/loader.js"></script>3. Načtěte rozhraní Graph API a přidejte funkci, která se spustí při načtení rozhraní API:
<script>
google.charts.load('current',{packages:['corechart']});
google.charts.setOnLoadCallback(drawChart);
// Your Function
function drawChart() {
...
}
</script>function drawChart() {
// Set Data
const data = google.visualization.arrayToDataTable([
['Contry', 'Mhl'],
['Italy', 55],
['France', 49],
['Spain', 44],
['USA', 24],
['Argentina', 15]
]);
// Set Options
const options = {
title: 'World Wide Wine Production'
};
// Draw
const chart = new google.visualization.BarChart(document.getElementById('myChart'));
chart.draw(data, options);
}Zkuste to sami →

<div id="myChart" style="width:100%; max-width:600px; height:500px;"></div>
<script>
google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
// Set Data
const data = google.visualization.arrayToDataTable([

const chart = new google.visualization.BarChart(document.getElementById('myChart'));
chart.draw(data, options);
}

Chcete-li převést pruhový graf na koláčový graf, stačí nahradit:
google.visualization.Sloupcový graf
s:
google.visualization.PieChart
const chart = new google.visualization.PieChart(document.getElementById('myChart'));Zkuste to sami →

Chcete-li koláč zobrazit ve 3D, přidejte do možností is3D: true:
const options = {
title: 'World Wide Wine Production',
is3D: true
