# Data Column Names

#### Data Column Names Tab

The Data Column Names tab shows the complete list of column names extracted from the raw timeseries files uploaded to BrightHub.

* The **Data Column Names** table lists the data column names extracted from the timeseries files, as well as the Statistic Type, Date From and Date To for each column name.\

* BrightHub groups the column names to be mapped to a logger measurement config:\
  for example, the average, standard deviation, maximum and minimum wind speed columns measured by an anemometer at 100m are grouped together and assigned to a logger measurement config with the measurement point name 'Spd\_100m'.
* The **Column Groups** section shows which data columns have been grouped together so each column group can be mapped to a logger measurement config.\

* To delete a column group, click the delete icon.\
  Note that doing so will also result in the deletion of any logger measurement config assigned to that group of measurements.
* You can also add column groupings to measurement columns which do not already belong to a grouping:

1. Under **Select data columns to group**, choose the *Ignored Columns* which you would like to group.
2. Click on Group Columns.
3. You can then assign the new column group to a logger measurement config and measurement point in the logger measurement config tab.

* The ignored columns are not considered in the data processing.\
  Only the grouped columns which belong to at least one column grouping are considered in the data processing.
