Add Background Image To Charts
SET THE BACKGROUND OF CHARTS TO AN IMAGE
Open the script editor for a widget, and copy in the following code:
widget.on('render', function(sender,event){
// URL to the background Image
var imageLink = 'http://siliconangle.com/files/2014/12/BlackWhite-Logo.jpg'
// Set the chart background as the image
sender.queryResult.chart.plotBackgroundImage = imageLink;
})
Change the imageLink variable to the path of your image, and hit save. Reload the web page and you should see an image as the background of your widget.

This functionality works only with the following chart types: scatter, pie, column, bar, line, area, & polar
