Hide Chart Elements

First of all, a visual chart, generated via Flex-Charting framework, is constructed with many layers of elements. They are series(data) layer, axis layer, background elements and annotation elements. Besides, you are able to create your own chart elements by implementing IChartElement2 interface.

Here are some quick tips:

• To kill the grid lines behind charts:
  backgroundElements=[]
• To make the grid lines drawn with larger interval:
   GridLines#horizontalChangeCount = larger_number;
• hide elements of axises
  AxisRenderer#showLabels = false;
  AxisRenderer#showLine = false;
  AxisRenderer#tickPlacements = "none";
