var start = 0.1;
var end = 6;
var points = ee.Array(ee.List.sequence(start, end, null, 50));
var values = points.log();

// Plot log() defined above.
var chart = ui.Chart.array.values(values, 0, points)
    .setOptions({

        viewWindowMode: 'maximized',
        ticks: [
          {v: 0},
          {v: 3},
          {v: end}]
      },
