I reproduced the problem in a sample app. It's not actually below 1 and not solid color (that was true for the data and settings in my actual application), but rather a "restarted" gradient below lowest y-value of an area. It happens when there are more multiple series. It looks like a rectangle is ...

When I used GradientRelative then area's color became solid below y-value of 1. But nevermind, we decided to simply disable area's antialiasing for the time being. Thanks for the assistance.

Is it possible to disable antialiasing for area series but enable it for line series on the same chart? I'd like to try to work around the problem by drawing antialiased line series over not antialiased area. Or maybe there is a better workaround? Not antialiased area doesn't look too well...

Unfortunately, this doesn't work for me if the data is irregular: Area area = new Area(); area.Color = Color.GreenYellow; area.AreaBrush.Gradient.StartColor = Color.GreenYellow; area.AreaBrush.Gradient.MiddleColor = Color.BlueViolet; area.AreaBrush.Gradient.EndColor = Color.Crimson; area.AreaBrush.G...

Thanks for reply, the first workaround works. However, I have another problem. When I use transparency and want to hide area lines, 1px-wide gaps appear. Can be reproduced with: Area area = new Area(); area.Color = Color.GreenYellow; area.AreaBrush.Gradient.StartColor = Color.GreenYellow; area.AreaB...

When I use area series, set up its gradient colors and then add it to chart, its gradient's StartColor is reset to some default value. MiddleColor and EndColor are correct. Please see the example below to reproduce: Area area = new Area(); area.AreaBrush.Gradient.StartColor = Color.GreenYellow; area...

I've got the same problem. Could you please send me an offline installer for the current version?
