class spinetoolbox.mvcmodels.time_series_model_fixed_resolution.TimeSeriesModelFixedResolution(series)

Bases: spinetoolbox.mvcmodels.indexed_value_table_model.IndexedValueTableModel

A model for fixed resolution time series type parameter values.

series

a time series

Type:TimeSeriesFixedResolution

indexes

Returns the time stamps as an array.

values

Returns the values of the time series as an array.

data(self, index, role=Qt.DisplayRole)

Returns the time stamp or the corresponding value at given model index.

Column index 0 refers to time stamps while index 1 to values.

Parameters:

• index (QModelIndex) – an index to the model
• role (int) – a role

flags(self, index)

Returns flags at index.

insertRows(self, row, count, parent=QModelIndex())

Inserts new values to the series.

The new values are set to zero. Start time or resolution are left unchanged.

Parameters:

• row (int) – a numeric index to the first stamp/value to insert
• count (int) – number of stamps/values to insert
• parent (QModelIndex) – index to a parent model

Returns:

True if the operation was successful

removeRows(self, row, count, parent=QModelIndex())

Removes values from the series.

Parameters:

• row (int) – a numeric index to the series where to begin removing
• count (int) – how many stamps/values to remove
• parent (QModelIndex) – an index to the parent model

Returns:

True if the operation was successful.

reset(self, value)

Resets the model with new time series data.

setData(self, index, value, role=Qt.EditRole)

Sets a given value in the series.

Column index 1 refers to values. Note it does not make sense to set the time stamps in fixed resolution series.

Parameters:

• index (QModelIndex) – an index to the model
• value (numpy.datetime64, float) – a new stamp or value
• role (int) – a role

Returns:

True if the operation was successful

batch_set_data(self, indexes, values)

Sets data for several indexes at once.

Only the values of the series are modified as the time stamps are immutable.

Parameters:

• indexes (Sequence) – a sequence of model indexes
• values (Sequence) – a sequence of floats corresponding to the indexes

set_ignore_year(self, ignore_year)

Sets the ignore_year option of the time series.

set_repeat(self, repeat)

Sets the repeat option of the time series.

set_resolution(self, resolution)

Sets the resolution.

set_start(self, start)

Sets the start datetime.
