How to use colors in error bars?

Adding a col= argument to error.bar() doesn't change the color of the error bars.
  This is an enhancement request that has been reported so that the developers can resolve it in a future version.  In the meantime attached is a script for another function called my.error.bar().  Copy this code to a script file in Spotfire S+ and run it with F10.  Then you will then need to replace error.bar() with my.error.bar() in your code.  Once this change has been made you will be able to specify colors for the error bars.
