+Note: As of v1.0.1, the attribute is now exposed to the directive allowing you to bind the zingchart directive to an actual DOM element along with the `<zingchart>` element. This will allow you to utilize percentage values in the height/width render options by maintaining a DIV's inherit properties. The following are equivalent :
+
+`<div zingchart zc-values="myValues"></div>`
+
+`<zingchart zc-values="myValues"></zingchart>`
