"Bug in Plot View - Surface 3D?"

Hallo,
I am inclined to think that there is a bug in the plot view - surface 3D. I think that the axis are swapped. But even if you interchange X and Y, the plot looks odd. For comparision, the Sticks 3D plot is o.k. Maybe someone can confirm this (or correct me)?
My example data (Excel):
X Y ratio
100 5 0,05
110 10 0,09
120 15 0,13
130 20 0,15
140 25 0,18
150 30 0,20
160 35 0,22
170 40 0,24
180 45 0,25
190 50 0,26
200 55 0,28
210 60 0,29
100 3,00 0,0300
110 3,25 0,0295
120 3,50 0,0292
130 3,75 0,0288
140 4,00 0,0286
150 4,25 0,0283
160 4,50 0,0281
170 4,75 0,0279
180 5,00 0,0278
190 5,25 0,0276
200 5,50 0,0275
210 5,75 0,0274
Thank you,
kind regards, Horst

I think we have resolved this problem already in our new version by removing this plotter
Greetings,
Sebastian
not exactly the kind of answer I was hoping for. Any chance to get this plotter back amended?
Kind regards, Horst
sorry, I think I missinformed you. When I tried to search for the plotter, I used a dataset with 150 rows, so the plotter was simply not shown in the selection. I should have taken a look into the message window.
It is included with less than 50 rows, so I will take a look, why the axis are exchanged.
Sorry for that,
Sebastian
no, the surface plotter was indeed not removed. However, it needs a very specific form for the data, i.e. it has to be rectangular in both base dimensions and both dimensions have to provide the same amount of values.
Cheers,
Ingo
thank you for your answers. Are my example-data not in line with these requirements? If not, could you give me an example, please? It would be nice if Sebastian was successful.
Thank you and kind regards, Horst
you could have a look into the sample process "..../sample/Meta/01_ParameterOptimization" and build the surface plot from the results of the parameter optimization.
Cheers,
Ingo
thank you for the hint.
I have run ...\rapidminer\sample\07_Meta\01_ParameterOptimization.xml and set a breakpoint after "ParameterOptimization - Grid..."; the result:
Table View:
C from 50 to 250
degree from 1 to 5
absolute ...
Plot View:
X = C from 1 to 5
Y = degree from 50 to 250
Z = absolute ...
So this plot confirms my observation that the axis are exchanged.
Kind regards, Horst

Ingo
