我正在使用googlechart创建一个饼图。但问题是,切片应该清晰可见。我尝试使用sliceVisibilityThreshold: 0
,但是具有较小值的切片不可见。
代码:
google.charts.load("current", { packages: ["corechart"] });
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Pizza');
data.addColumn('number', 'Populartiy');
data.addRows([
['Pepperoni', 1062],
['Hawaiian', 5229],
['Mushroom', 0],
['Sausage', 0],
['Anchovies', 14] // Below limit.
]);
var options = {
title: 'Popularity of Types of Pizza',
sliceVisibilityThreshold: 0,
pieStartAngle: 0,
is3D:true
};
var chart = new google.visualization.PieChart(document.getElementById('piechart'));
chart.draw(data, options);
}

<div id="piechart"></div>
