For a chart with dynamic data, you can set colors of chart series dynamically based upon expressions. To use the feature, do the following steps:

• Declare a chart with dynamic data in the usual way

• For chart series to be colored dynamically, define corresponding color expressions in names of these series using seriesColor tags having the following syntax:

  <<seriesColor [color_expression]>>
  

A color expression must return a value of one of the following types:

• A string containing the name of a known color, that is, the case-insensitive name of a member of the KnownColor enumeration such as “red”
• An integer value defining RGB (red, green, blue) components of the color such as 0xFFFF00 (yellow)
• A value of the Color type
