I am very thankful for ending my search of conditionally flex charts.
THANKS A LOT.

Grant,

I used (and slightly modified) you columnRenderer class. Thank you for the great work!

jwopitz,
Thanks for pointing that out. I created this functionality for a project that I was doing about a year ago, before Flex 3 came out. To my knowledge the fillFunction wasn’t in Flex 2.

I wish it were, it would have saved me a lot of time (and hair).

I haven’t used fillFunction yet, but it looks like it will do the same work.

Great find!

I am rather new to charts though have been developing Flash/Flex for a long time.

I am curious to know if you could achieve the same thing by implementing the fill logic via the fillFunction for the series. Would it enable gradients or just solid colors?

Thanks,
Justin

Chuck,

Maybe you should be writing the articles and I should be the one learning. hehee.

Thanks for your additions, I’m sure that someone will be very happy with them.

Added more to that else {} block.

var alpha:Number = 1;
if( d.hasOwnProperty( “alpha” ) )
alpha = d.alpha;

if( d.hasOwnProperty( “color” ) )
g.beginFill( d.color, alpha );
else
g.beginFill( _defaultColor, alpha );

by the way, thanks for the great tool, it works great with hard values in the ranges, but I’m trying to use data binding and am not having any success.

For example, instead of using your lowerLimit=”240″ you use lowerLimit=”{GetLimit( 240 )}”

GetLimit is defined to return numeric value. I’m having issues with the compiler, it says GetLimit is an undefined method. If I put GetLimit() in the ItemRender class it works fine, but that isn’t ideal.

My above comment, I figured out the code to be:

else
{
if( d.hasOwnProperty( “color” ) )
g.beginFill( d.color );
else
g.beginFill( _defaultColor );
}

The code at the bottom of fillgraphics() needs a bit of tweaking.

You have else { use default color } but no check if d.color is defined.

//g.beginFill( _defaultColor );
g.beginFill( d.color );

works, but it should be something like sudocode

if( d.color defined )
g.beginFill( d.color )
else
g.beginFill( defaultColor );

Hi Graham,

Can you post a little bit of code for me? I’d like to see if I can figure out what you are doing differently.

Thanks,
Grant
