Data structure
Data structure incorporated in LeoStatistic could be described as a array of
tables. A term "data" is used here in a sense of a collection of numerical
measurements (in most broad sense like an output of physical experiment,
customers data, price - time series etc.) that could be organized in a form of a
tables. One column of data also refers here as (field or variable) has several
attributes:
name
status to be an Argument, a Value or Inactive;
marker's color, shape and size for values.
Data structure is organized as a collection of tables
with the same number of columns (parameters) these (tables) could have different
number of records. All of these tables must to have exact the same ordered
assignment of parameters by their status.
There is a principal example of data structure organization in LeoStatistic
as it could be seen outside:
Series 1
Name: x y z
Status: A V I
Shape: N/A square N/A
Color: N/A blue N/A
Size: N/A 3 N/A
1 0 4 11
2 0.25 4.0 11.5
3 0.5 4.25 13.0
4 0.75 4.5 15.8
5 1 5 20
6 1.25 5.5 25.9
7 1.5 6.2 34.0
8 1.75 7.0 44.8
9 2 8 59
10 2.25 9.0 77.1
11 2.5 10.2 100.0
12 2.75 11.5 128.6
13 3 13 164
14 3.25 14.5 207.0

Series 2
Name: x v z1
Status: A V I
Shape: N/A circle N/A
Color: N/A green N/A
Size: N/A 9 N/A
1 0.01 -5 22.5
2 0.33 -4.9 19.6
3 0.66 -4.7 17.2
4 0.99 -4.0 11.2
5 1.32 -2.7 2.2
6 1.65 -0.5 -4.7
7 1.98 2.7 2.6
8 2.31 7.3 48.6
9 2.64 13.3 174.5
The screenshot of LeoStatistic corresponding to the above set of data is
presented here:

The largest number of records in one series that
LeoStatistic can handle programmable is 232= 1010 cells
(number rows*number columns for all data series). But, of course, realistically
speaking much smaller data sets can be calculated without lost of patience with
the help of modern computers. But as soon it's subjective - try for yourself.
An internal presentation of the data structure in LeoStatistic is of course
differ - all data a in one array. LeoStatistic is using a
NetCDF format for storage or
data as properly one. Our LeoNetCDF application could be used for observing and
in some extend modification of data and data setting although we don't recommend
it.
