A Recent update to the online service has changed the way fields are displayed when using the drilling down all functionality. For my scenario I have distributors, reps and customers. When I use the drill down all function the chart now shows distributor rep customer all in one line. This is way too much text for a chart and we don't need this functionality for this chart. This issue doesn't happen in desktop but only when I publish to the web. Please help i'm getting multiple complaints on this topic. For more info and other users having similar issues you can see the ideas forum link below. The user zapppsr has a good recommendation I believe would be the best. http://community.powerbi.com/t5/Service/How-to-disable-the-automatic-inline-hierarchy/m-p/62180#M12153
