Is there a sample code similar to that for pie charts in this thread, that
would show how to build JSON data for a vertical bar chart?
I'm currently using a version with hard coded data that works fine, but
would like to read the data from a mysql database using a JSON formatted
data table. Any example of how to generate that JSON table for a bar chart
would be much appreciated.
<script type="text/javascript">
google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Strategy', 'Cumulative Percentage Returns'],
['Core', 229 ],
['S&P 500', 77 ]
]);
var options = {
'backgroundColor':'#f2f9f6',
'width':300,
'height':300,
'legend': {position: 'none'},
'colors': ['blue'],
'vAxis': {baselineColor:'blue', baseline:0, gridlines: {count:-1},
textStyle: {color:'red', bold:'true'} },
'hAxis': {textStyle: {fontName:'Trebuchet MS', fontSize:10,
color:'black', bold:'true'} },
'fontName':'Trebuchet MS'
};
var chart = new
google.visualization.ColumnChart(document.getElementById('core_chart_cumulReturns'));
chart.draw(data, options);
}
</script>
