Where are the EmbeddedChart setOptions options?
<p>I am using the <a href="https://developers.google.com/apps-script/reference/spreadsheet/embedded-chart-builder" rel="nofollow noreferrer">EmbeddedChartBuilder</a> to create charts dynamically, which is working fine. Basic example:</p>

<pre><code> var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
 var sheet = spreadsheet.getSheetByName('Charts');
 var chart = sheet.newChart()
    .setPosition(1, 1, 0, 0)
    .setChartType(Charts.ChartType.AREA)
    .addRange(spreadsheet.getSheetByName('Data').getRange("A1:A10"))
    .build();
 sheet.insertChart(chart); 
</code></pre>

<p>However I need to customize the charts using the <code>setOption</code> method. <a href="https://developers.google.com/apps-script/reference/spreadsheet/embedded-chart-builder#setoptionoption-value" rel="nofollow noreferrer">The documentation says</a>:</p>

<blockquote>
  <p>Sets advanced options for this chart. See
  <a href="https://developers.google.com/chart/interactive/docs/reference" rel="nofollow noreferrer">https://developers.google.com/chart/interactive/docs/reference</a> for
  what options are available.</p>
</blockquote>

<p>But following the link they give (/chart/interactive/docs/reference), the only thing I see is this:</p>

<p>Trying to find <code>vAxis</code> doesn't lead anywhere. <a href="https://developers.google.com/chart/interactive/docs/customizing_charts" rel="nofollow noreferrer">Looking at another page on advanced chart customization</a>, once again I see examples but not the reference:</p>

<pre><code>var options = {
  width: 400,
  height: 240,
  title: 'Toppings I Like On My Pizza',
  colors: ['#e0440e', '#e6693e', '#ec8f6e', '#f3b49f', '#f6c7b6']
};
</code></pre>

<p><strong>Where is the list of all available options for the <code>setOption</code> method?</strong></p>
