Types ¶
type Tabulator ¶
type Tabulator struct {
Timestamps indexer[time.Time]
Columns indexer[string]
Data [][]float64
// contains filtered or unexported fields
}
Tabulator tabulates a set of entries in rows by timestamp and columns by label. For performance reasons, Data must be added sequentially.
func (*Tabulator) Accumulate ¶
func (t *Tabulator) Accumulate()
Accumulate increments the values in each column.
func (*Tabulator) Add ¶
Add adds a value for a specified timestamp and column to the table. If there is already a value for that timestamp and column, the specified value is added to the existing value.
Returns false if the column does not exist. Use RegisterColumn to add it first.
func (*Tabulator) Filter ¶
Filter removes all rows that do not fall inside the specified time range. If the specified time is zero, it will be ignored.
func (*Tabulator) GetColumns ¶
GetColumns returns the (sorted) list of column names.
func (*Tabulator) GetTimestamps ¶
GetTimestamps returns the (sorted) list of timestamps in the table.
func (*Tabulator) GetValues ¶
GetValues returns the value for the specified column for each timestamp in the table. The values are sorted by timestamp.
func (*Tabulator) MarshalJSON ¶ added in v0.3.0
func (*Tabulator) RegisterColumn ¶
RegisterColumn adds the specified columns to the table.
func (*Tabulator) SaveBinary ¶ added in v0.3.0
func (*Tabulator) Set ¶
Set sets the value for a specified timestamp and column to the table.
Returns false if the column does not exist. Use RegisterColumn to add it first.
