RE: [flexcoders] Re: Linear Gradient with AreaChart bug?

You could write a custom area renderer to do it. If you look at the code for the default area renderer, you'll see that it's computing the bounding box of the values of the series, and using that as the rectangle for the IFill.begin() call.  I believe area renderers are actually sized to fill the entire data area of the chart, so if instead you passed Rectangle(0,0,unscaledWidth,unscaledHeight) as the rectangle for the IFill.begin() call, you should get the effect you want.   Ely.   From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of twgonzalez01 Sent: Wednesday, November 01, 2006 1:53 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Re: Linear Gradient with AreaChart bug? I Went to create a test case (as the source code is part of a much larger app) and realized what is happening. In an area chart the linearGradient is only creating a Matrix transformation between the Min and Max values within that Series, not the min/max for the overal Y Axis. So if there is a small delta between the min/max within the series, but the overall values are high up on the Y axis you only have a very small area that the gradient gets applied to. Is there any way around this? --- In [EMAIL PROTECTED]ups.com, "Ely Greenfield" <[EMAIL PROTECTED].> wrote: > > > > > Tom, can you post a full sample with a description of what you're > seeing, and what you expect to see? > > Gradients should fill the bounding box defined by the area series. > > E. > > > ________________________________ > > From: [EMAIL PROTECTED]ups.com [mailto:[EMAIL PROTECTED]ups.com] On > Behalf Of twgonzalez01 > Sent: Wednesday, November 01, 2006 11:29 AM > To: [EMAIL PROTECTED]ups.com > Subject: [flexcoders] Linear Gradient with AreaChart bug? > > > > I am trying to create an area chart and use a LinearGradient at 90 > degrees (top-bottom) fill for the areaFill. > > The problem is that the matrix transformation appears to not be taking > into account the full range of Y values, and all transitions are > occuring in the very top of the chart.
