I would like to show several histogram data in a 3d plot, to see which histogram maximum is not "in line", but boxes are not allowed in splot. Increasing the linewidth does not produce readable plots. Also the fence type plot isn't available for data input.
The alternative to show transparent plots produces one single plot because the data is not divided in separate plots.
My data is in the form
1 y1 z1
1 y2 z1

1 yn zn

2 y1 z1
2 y2 z2

2 ym zm

3 etc, each block separated with 2 newlines

How can I divide this data like it is divided in plot file1, file2, file3… ?
Any suggestions for the waterfall?

Chris
