To be able to see the results and work with them, the results from a project needs to be stored. There are different ways of storing data in BellaDati ML Studio - permanently and temporarily. For storing the data permanently, they need to be stored in data set. Temporary storage is available only for current session. Tables and various charts can be used as temporary storage (temporary output). These tables and charts are deleted after end of each session.
To be able to store data in data set, the data set with correct structure (attribute and indicators) needs to be already created. See Creating Data Set for more information.
Function storeDataset is used for storing the data. The function is defined like this:
storeDataset(Integer datasetId, InputStream is, Map<Object, Object> params) |
All parameters are mandatory.
table('temptable', [ [ 1, 2 ], [ 2, 3], [ 3, 4] , [ 4, 5] ], 'Column 1','Column 2') storeDataset(16, streamTable('temptable'), ["mapping": "M_COLUMN_1,M_COLUMN_2","method" : "delete_all"]) |
This code will first create a temporary table 'temptable' and then store in data set with ID 16. First column of the table is mapped to indicator with code M_COLUMN_1, second column is mapped to indicator with code M_COLUMN_2. Method delete_all is used and therefore all existing data in the target data set will be deleted before storing data from the table.
table('temptable2', [ 1,2,3,4], 'Column 1'); storeDataset(17, streamTable('temptable'), ["mapping": "M_COLUMN_1","method" : "delete_all", fill : "M_COLUMN_2=10"]) |
This code will first create a temporary table 'temptable2' with one column and then store in data set with ID 17. The column of the table is mapped to indicator with code M_COLUMN_1. Second column with code M_COLUMN_2 will be filled with number 10 (all rows). Method delete_all is used and therefore all existing data in the target data set will be deleted before storing data from the table.
Data can temporarily stored (displayed) as:
Temporary table can be used for displaying results in a form of rows and columns. List of tables is displayed in control sidebar on left side of the screen in section Tables. The table itself is displayed in the right sidebar. It is also available to download it as a CSV file.
Function table is used for storing the data in table. The function is defined like this:
table(String id, Object data, String... columns) |
Parameter data is mandatory, parameters id and columns are optional.
table('first', [ [ 1, 2 ], [ 2, 3], [ 3, 4] , [ 4, 5] ], 'Column 1','Column 2') table([ [ 1, 2 ], [ 2, 3], [ 3, 4] , [ 4, 5] ], 'Column A',) |
This code will create two tables with the same content. The first table has defined its name and names of both columns. Second table does not have its name defined and therefore it will be named as table_2. It also has defined name only for the first column. The second will be named automatically as 1.
This feature allows you to save media files from script execution. String or InputStream as parameter.
Long saveMediaFile(String name, String filename, String contentType, InputStream is) Long saveMediaFile(String name, String filename, String contentType, String data) example saveMediaFile("file title", "test.txt", "text/plain", "some content") |
It is possible to display results in a form of a bar chart. List of charts is displayed in control sidebar on left side of the screen in section Charts. The chart itself is displayed in the right sidebar.
Function barChart is used for displaying the data as a bar chart. The function is defined like this:
barChart(String id, Object data, Map<Object, Object> params, String... columns) |
Parameter data is mandatory, parameters id, params and columns are optional.
barChart('bar chart',[1, 2, 3, 2, 1],["color":"#09DDCC"],'Results') |
This code will create a bar chart with the name "bar chart", with five columns, cyan color and label "Results" on X axis.
Another option is to display results in a form of a box plot chart. List of charts is displayed in control sidebar on left side of the screen in section Charts. The chart itself is displayed in the right sidebar.
Function boxPlotChart is used for displaying the data as a box plot chart. The function is defined like this:
boxPlotChart(String id, Object data, Map<Object, Object> params, String... columns) |
Parameter data is mandatory, parameters id, params and columns are optional.
min
max
avg
median
first quartile
third quartile.
boxPlotChart([[ 1,3, 10, 5, 6, 3.2, 7]] , ["start":1, "color": "lightblue"] ) |
data = [ [ 'First', 1, 10, 5, 6, 3.2, 7 ], [ 'Second', 4, 14, 9, 10, 6.2, 10 ], [ 'Third', 4, 14, 9, 10, 6.2, 10 ] ] boxPlotChart(data, [ "start": 1, "labels": 0, "color": "purple", "scale": "relative"] ) |
table('temptable', [ [ 1, 2 ], [ 2, 3], [ 3, 4] , [ 4, 5] ], 'Column 1','Column 2')storeDataset(16, streamTable('temptable'), ["mapping": "M_COLUMN_1,M_COLUMN_2","method" : "delete_all"])
