[jCharts-users] 3D charts in their infinite variety

[Chris M. <ch...@de...>]

Hi,

A couple of questions for users of Jcharts, looks pretty slick BTW.

Has anyone done any work on rendering the bar charts in a 3D look? I'm
guessing this could be implemented using a custom renderer? Am I on the
right track?

Now for something tricker: What about 3-d, for example y-axis plots a
value, x-axis plots the days, and z-axis plots the hours within the day
?

Any info would be greatly apprciated,

Regards, Chris

Not yet.  I just brought back the 3d pie from jcharts 0.2 (still have a little work to do).  A 3d 
looking bar would not be too difficult to implement.  A cheap way to do it would be to simply draw
a bar several times(depth), off setting one by a pixel down and to the side.  Sort of sliding the
bar without clearing the image.  Simply trap the first and last to draw a border, then draw the
other edges. (see attached 3d pie chart)

Same approach, but subdivide the depth by the number of bars in each cluster for a clustered 3d
look.
