Usage of background image for charts

With parameter "canvas_class" you set css styling options for the used canvas. With it you may set a background color or background image for your chart. You may define this via a style sheet or set it inline within your article:
.cvs-euro {
    background-image: url('/media/plg_content_rgraph/images/euro.jpg');
    background-size: 100% 100%;
    background-repeat: no-repeat;";
