<button type="button" onClick = "document.getElementById('chartdiv').style.height = 200px">Click Me!</button>
<div id="chartdiv" style="width: 100%; height: 50px; background-color:#E8EDF2"></div>

Just a silly mistake use quote('') in '200px'

<button type="button" onClick = "document.getElementById('chartdiv').style.height = '200px';">Click Me!</button>
<div id="chartdiv" style="width: 100%; height: 50px; background-color:#E8EDF2"></div>
</body>
Do this:
function changeHeight() {
document.getElementById('chartdiv').style.height = "200px"
}
<button type="button" onClick="changeHeight();"> Click Me!</button>
