I am unable to get a Surface 3D chart to display when I add X, Y, and Z values to the surface using 3 ArrayLists of Doubles.

The axes are visisble, the legend is visible, everything is visible except the actual data surface. If I simply change ss.add(xV, yV, zV), where xV, yV, and zV are populated ArrayLists, to ss.fillSampleValues(100) the surface is visible. I have called setIrregularGrid(true).

While the values in each ArrayList have a wide dynamic range, the axis labels are reasonable and thus I would expect the surface to appear. What am I missing?

Hi Jack,

Probably your data doesn't accomplish with surface series requirements. Such series work as I explained here. If you think your data fits in this structure please post a simple code snippet we can run "as-is" to reproduce the problem here.

Thanks in advance.
