I have a matrix of tripples {x,y,z}. The x is the same for all
tripples in a row the y is the same for each tripples in column.
Some tripples a substitude bei Null as the represent unvalid results.

The may be deleted by
Delete[lumpi, Position[lumpi, Null]]

Now I want a nice 3D-picture.

Flatten[%, 1];
ScatterPlot3D[%, BoxRatios -> {1, 1, 0.8}];

is not very good as there arre only points.

Flatten[%, 1];
Show[Map[ScatterPlot3D[#, DisplayFunction -> Identity, 
          PlotJoined -> True] &, %%%], DisplayFunction -> $DisplayFunction, 
    BoxRatios -> {1, 1, .8}];

does ScatterPlot3D to each row which looks better but not perfekt.

Any ideas to build a "nice" picture?

Many thanks, also for answers to my other questions.
