示例
代码编辑器 (JavaScript)
print(ee.Array([-4]).cosh()); // [~27.31]
print(ee.Array([0]).cosh()); // [1]
print(ee.Array([4]).cosh()); // [~27.31]
var start = -4;
var end = 4;
var points = ee.Array(ee.List.sequence(start, end, null, 50));
var values = points.cosh();
// Plot cosh() defined above.
var chart = ui.Chart.array.values(values, 0, points)
.setOptions({
viewWindow: {min: start, max: end},
hAxis: {
title: 'x',
viewWindowMode: 'maximized',
ticks: [
{v: start},
{v: 0},
{v: end}]
},
lineWidth: 1,
pointSize: 0,
});
print(chart);
