The next version will probably add support for 3D charting primitives (bars, stacked bars, lines, splines?). What kind of options would you like to see here? This will help me to figure out the dev priorities. Thanks you all! JD.

3D bar chart looks promising!  Did you think about other shapes of bars than square (eg. round bars)? Setting POV would also be great, but these are just visual enchancements that aren't so important  Will there be image maps in 3d graphs? And transparency of 3d bars? I thought of onmousehover over a color on a legend will set transparency of other bars, so they will not hide the bar that is behind them (but that would be hard to do on static image, or even impossible)

Transparency is already coded but the visual result isn't that good  Image maps will be a piece of cake now that the core functions exist since the 2.1.2. I'm focusing on 45° perspective view for now. I can try to add support for pyramids & cylinders as they're the most common 3D shapes on charts. The onMouseOver events are possible if handled via JS -even if not really thinked yet- the script can create one full image and small parts that may be loaded via JS depending of the mouse position. This can be indeed really great stuff to have ;o)

How about frames only? And how would absissa look like? and horizontal lines, when the bars are placed perspectively? I will think about solution to the transparency Edit: new idea: Cylinder gauge Not like bar chart, but single cylinder. Cyllinders filled to some point (image is just to help you imagine  ) Also, may be stacked

3D charts open up fantastic capabilities.. molecules immediately come to my mind..

also 3D vector algebra would be possible as catchwords: scalar product, Euclidean space

@chartbreaker nice, but what does it have to do with charts?

don't constrain your imagination  it's not so far to come to a third axis from 3Dcharts a line is already a vector (without an arrow) and when you draw a 3D bubble chart, put some lines between the bubbles... voilá you have a molecule |

I'm not sure yet of the way I'll use to do the 3D effect, basically it would be easier for me to stay "isometric" with a fixed 45° angle but indeed..free angle & point of view would be ideal. I'm not sure that my mathematical skills are enought for this. Sticking to the visual I've added a funcky function to draw a mirror effect ;o)

mirror effect looks neat! I was thinking about transparency in 3d charts. How does it look with lower alpha? and can you make, that only front two and the top side is visible? I just would like to know how would it look like. And how about absissa on 3d graphs?
