The FlexChart allows you to specify gradients for series style properties. The gradients are specified as strings with the following syntax:



  1. {type} is either 'l' or 'r', for linear or radial gradients,
  2. {coords} is a set of three or four numbers that specify the gradient direction (x1/y1/x2/y2 for linear, for radial), and
  3. {color:offset:opacity} is an HTML color string optionally followed by offset and opacity values. You may add add additional colors using a hyphen as a separator.
