# What is the difference between spiral, flame, aggregation data

What is the difference between spiral, flame, aggregation data? What are the names of the columns, or what are the columns indicate? For example, spiral is like to:

31.95   7.95    3
31.15   7.3     3
30.45   6.65    3
29.7    6       3
28.9    5.55    3
28.05   5       3
27.2    4.55    3
26.35   4.15    3
25.4    3.85    3
24.6    3.6     3
23.6    3.3     3
22.75   3.15    3
21.85   3.05    3
20.9    3       3


Flame is like to:

1.85    27.8    1
1.35    26.65   1
1.4    23.25    2
0.85    23.05   2
0.5    22.35    2
0.65    21.35   2
1.1    22.05    2
1.35    22.65   2
1.95    22.8    2


Aggregation is like to:

15.55   28.65   2
14.9    27.55   2
14.45   28.35   2
14.15   28.8    2
13.75   28.05   2
13.35   28.45   2
13       2.15   2
13.45   27.5    2
13.6    26.5    2
12.8    27.35   2


I searched but couldn't find a source to illustrate the difference or which columns indicate?

Generally, without knowing the source of the data, we can't tell you much about the columns. But I assume the first two columns correspond to $$x$$ and $$y$$. The third is probably some meta-data? Maybe a cluster number?

For an illustration I found this figure coming from this publication. Maybe that helps you imagine the data's shape. https://www.researchgate.net/publication/338167806_A_Fast_Method_for_Estimating_the_Number_of_Clusters_Based_on_Score_and_the_Minimum_Distance_of_the_Center_Point

• thanks for replying .. so treating with each type of them will be different ? – mohe Feb 19 at 4:50
• These don't seem to be different kinds of "treatment" in any sense, but rather descriptions of the underlying data shape that results in these shapes. Having a biology background, b) could for example be clusters of cells that behave similarly along the two axis or c) somewhat of a volcano plot. – ttreis Feb 19 at 8:48
