Contoh
Code Editor (JavaScript)
print(ee.Array([0.1, 1, 10, 100]).log10()); // [-1,0,1,2]
var start = 0.1;
var end = 100;
var points = ee.Array(ee.List.sequence(start, end, null, 50));
var values = points.log10();
// Plot log10() defined above.
var chart = ui.Chart.array.values(values, 0, points)
.setOptions({
viewWindow: {min: start, max: end},
hAxis: {
title: 'x',
viewWindowMode: 'maximized',
},
vAxis: {
title: 'log10(x)',
},
lineWidth: 1,
pointSize: 0,
});
print(chart);
