Our customers have really liked the ability to use their own graphic backgrounds in their bubble charts that we introduced in Version 4.0, but sometimes the image is too strong as a background to permit adequate contrast of the chart objects. Version 4.1 adds a slider to the preferences that allows you to precisely fade or darken the background image to improve the graphic contrast, and help your bubbles pop-out from the image. In the example shown here, you can see how fading the background slightly helps the bubbles stand-out more from the image.
