Hi,
I am using highcharts with gxt.
I am setting an image as background to my chart's plot area like this:
chart.setOption("/chart/plotBackgroundImage",backGroundImageURL);
But my charts have different sizes and image is distorted on some of the charts.
So I want to set a size (height -width) to the background image.
Is it possible?
