Why Google charts' width not working when change display from none to block?

I create a Google charts' with width=100%:

<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<script type="text/javascript">
google.charts.load("current", {packages:['corechart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
  var data = google.visualization.arrayToDataTable([
    ["test", "val", { role: "style" } ],
    ["test", 21.45, "color: red"]
  ]);
  var options = {
          height: '300px',
          width: '100%'
          };
  var view = new google.visualization.DataView(data);
  var chart = new google.visualization.ColumnChart(document.getElementById("columnchart_values"));
  chart.draw(view,options);
  }
</script>
<div id="columnchart_values"></div>

Then, I create the same charts with display=none beginning. and shows chart after click:

<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<script type="text/javascript">
  google.charts.load("current", {packages:['corechart']});
  google.charts.setOnLoadCallback(drawChart);
  function drawChart() {
    var data = google.visualization.arrayToDataTable([
  ["test", "val", { role: "style" } ],
  ["test", 21.45, "color: red"]
    ]);
    var options = {
          width: '100%'
          };
    var view = new google.visualization.DataView(data);
    var chart = new google.visualization.ColumnChart(document.getElementById("columnchart"));
    chart.draw(view,options);
    }
  function test() {
  document.getElementById("columnchart").style.display = "block";
  }
</script>
<div onclick="javascript:test()"> click me </div>
<div id="columnchart" style="width: 100%; height: 300px; display:none;"></div>

But it seems in the second method, Google charts' width style not working and only show the default width. Can anyone helps me? Thank you very much!
