Removing some x axis labels on Google Charts

Question

I'm currently making this graph with a ton of labels on the x access which make it look crowded, can someone please point me to the right direction where I can change it where the x-axis only shows 1990, 1995, 2000, 2005, 2010, and 2015. Thank you very much

      function drawChart() {
    var data = google.visualization.arrayToDataTable([

Answer 1

if you use numbers --> 2010 -- instead of strings --? '2010'
then you can control which labels appear by using the ticks option...

    hAxis: {
      ticks: [1990, 1995, 2000, 2005, 2010, 2015]
    }

see following working snippet...

google.charts.load('current', {packages: ['corechart']});
google.charts.setOnLoadCallback(drawChart);

function drawChart() {
  var data = google.visualization.arrayToDataTable([
    ['Year', 'Moore',   'Edmond', 'Norman'],
    [1990,  40332,      52380,   80435],
    [1991,  40904,      53884,   81718],
    [1992,  41554,      55477,   83300],
    [1993,  42427,      57334,   85004],
    [1994,  43151,      59470,   86932],
    [1995,  43679,      61281,   88387],
    [1996,  44241,      62892,   89562],
    [1997,  44859,      64115,   91921],
    [1998,  45233,      65145,   93073],
    [1999,  45431,      66757,   94193],
    [2000,  41477,      68607,   96882],
    [2001,  42439,      69357,   98530],
    [2002,  43909,      70644,   99222],
    [2003,  45071,      71707,   100437],
    [2004,  46595,      73254,   100983],
    [2005,  48179,      75456,   102297],

    [2007,  51279,      78066,   106168],
    [2008,  52852,      79890,   107636],
    [2009,  54026,      81653,   109447],
    [2010,  55396,      81466,   111380],
    [2011,  56706,      82943,   113872],
    [2012,  57840,      84936,   115629],

    [2018,  62103,      93127,   123471],
  ]);

  var options = {
    title: 'Population of Moore Oklahoma',
    curveType: 'function',
    legend: { position: 'bottom' },
    hAxis: {
      format: '0',
      ticks: [1990, 1995, 2000, 2005, 2010, 2015]
    }
  };

  var chart = new google.visualization.LineChart(document.getElementById('curve_chart'));

  chart.draw(data, options);
}
