Good morning in PDT, and thanks for being here.
Me: new to AS Flex, building a Linux-based dashboard, using
Flexbuilder alpha for Linux in Eclipse
( this does not have all features compared to Windows and OSX I believe,
and may be buggy)
*Problem:* I've been given an XML schema for incoming data
Hey I see what you are doing, including a call I didn't know about...

stuff I didn't get that tripped me up-
1) You don't have to use the mx:ColumnChart at all - you can do
everything in AS instead.
well it may be easier... but I liked the obvious page layout of the mx
tags, separated from the AS code. No doubt I can still have what I want.
My comment on the documentation is that as long as you are using very
simple data, everything goes together smoothly, but as soon as I

I see String.replace using a regex, but is there a more straightforward
way to do this (very) common adjustment?

and of course you're right if they irritate my sense of code style, I
can just wrap them up.

I must be doing something simple wrong here.
What I am doing:
creating a column chart entirely in AS, and controlling the colors, and
series, and legend in AS. The legend will be in a grid, instead of
automatic in the chart.
once the XML data is acquired, the makeserviceschart assembles the

This code ( in the adobe example) works:

Just in case anybody cares, it is also possible to use Flex Builder on

The key here is that the OS reads the hosts file first and then asks
DNS, so whatever you put in will override what
is using http://localhost:8080
and localhost works without manually adding it in the hosts file (usually ?)
