Google Charts (JS) - is there a way of using a transparent background on a chart?
In the Configuration Options of the chart, specify
backgroundColor: { fill:'transparent' }
This worked for me in Chrome and Firefox. It took me some time to find out. The doc page says you can only put in HTML color strings and I assumed 'transparent' was not one of them.
Setting a transparent background for Google Charts:
// Set chart options
var options = {'title':'Chart Title',
'width':600,
'height':300,
'backgroundColor': 'transparent',
'is3D':true
};
