Default 3D chart transparency with ASP.NET Chart Control?

Question

Hello,

like two guys before me there and second one there I have difficulty with 3D chart.

How to force them to be transparent like this picture:

taken from 3D Area chart example shipped with ASP.NET Chart controls. This chart has ChartColorPalette.BrightPastel pallete, but is transparent.

I have also 3D chart with ChartColorPalette.BrightPastel palette, but is not transparent and I still cannot found way how to make it transparent like example chart. (After examining example markup and codebehind):

The only way I've found is to set the color of series with alpha channel for transparency, or use color palette with transparent colors (for example ChartColorPalette.SemiTransparent) but there must be some other default way which I'm missing.

Reason I really need this to know is that I'm creating graphs without any code behind just using markup, so I'm finding it a little bit redundant to create code snippets only because of this.

Thank you very much for any answers.

Edit: I'm using .NET 3.5 version of ASP.NET charts.

I see you're on this thread too. Unfortunately, you do need to use colors with an alpha channel in order to set transparency AFAIK

Here's a good overview of the palettes available and some basics on manipulating them

My guess is that you could create a new palette by iterating over the colors in the bright pastel palette and adding an alpha channel - if you do this in a global static, perhaps as part of your webapp init logic, you should be able to reference it pretty easily - if you don't want to have any codebehind, you ?may? be able to databind your custom palette to the CustomPalette property, but I can't say with certainty.
