grapa.database.Database

class grapa.database.Database(data, colLabels: list | None = None, rowLabels: list | None = None, rowLabelNums: list | None = None)

Bases: object

Database is not quite a Graph. Used to store data as table with labels. Database can be instancied 2 ways:

• by providing a Graph object

• by provinding data: np.array, colLabels, rowLabels the labels of the columns, respetively the rows, and rowLabelNums a numeric index corresponding the row label.

__init__(data, colLabels: list | None = None, rowLabels: list | None = None, rowLabelNums: list | None = None)

Methods

__init__(data[, colLabels, rowLabels, ...])
clean()
colIdFromLabel(y)
colValuesFromId(x)
deleteRow(row_idx)
getAttr(key)
getColLabel([i])	Returns label of column i.
getRowLabel([i])	Return the row label.
getRowLabelNum([i])	Return the numeric equivalent for the row label.
mask_from_conditions(tests)
merge(other)
plot(x, y[, linespec, xlim, ylim, also])	deprecated plot function
plot2(x, y[, linespec, xlim, ylim, ...])	plot the data of the Database Possible use case: .
renameColumn(oldname, newname)	Change the label of a column.
rowIdFromLabel(label)
setRowLabel(newlabel[, i])	Change the row label.
setValue(col, row, value[, silent])
shape([idx])	Returns the shape of the np.ndarray data container.
update(attr)
value(col, row[, silent])

getColLabel(i=':')

Returns label of column i.

getRowLabel(i=':')

Return the row label.

getRowLabelNum(i=':')

Return the numeric equivalent for the row label.

plot(x, y, linespec='x', xlim: list | None = None, ylim: list | None = None, also: list | None = None)

deprecated plot function

plot2(x, y, linespec='x', xlim: list | None = None, ylim: list | None = None, complement: dict | None = None, also: list | None = None, filesavesuffix='')

plot the data of the Database Possible use case:

testEffId1 = [['Eff. [%]', '>=', 19], ['row', '<',  2700]]
testEffId2 = [['Eff. [%]', '>=', 19], ['row', '>=', 2700], ['row', '<', 2884]]
testEffId3 = [['Eff. [%]', '>=', 19], ['row', '>=', 2884]]

def alsoEff(x, y, color):
    return [[x, y, 's'+color, testEffId1],
            [x, y, 'v'+color, testEffId2],
            [x, y, 'sr', testEffId3]]

dbProcess.plot('row',
               'Eff. [%]',
               linespec='xk',
               xlim=[2350, np.ceil(max(dbProcess.rowLabelNums)/50)*50],
               ylim=[15, 21],
               also=alsoEff('row', 'Eff. [%]', 'k'))

renameColumn(oldname, newname)

Change the label of a column.

setRowLabel(newlabel, i=-1)

Change the row label. If i=-1 self.rowLabel is modified (default ‘Growth TL nb’)

shape(idx='')

Returns the shape of the np.ndarray data container.
