Often, it is useful to rename a frequently-used field directly in the dataset, instead of using an alias in each visual.
The following steps demonstrate how to rename a field. We are using the column
iso_cc
(the ISO-compliant country code) in the dataset World Life
Expectancy [data source: samples.world_life_expectancy
].
On the main navigation bar, click Data.
The Data view appears, open on the Datasets tab.
In the Datasets area, select
World Life Expectancy
(samples.world_life_expectancy)
.
In the Dataset Detail menu, select Fields.
In the Fields interface, select Edit Fields.
Under Dimensions, find the field iso_cc
, and
click the (down arrow) icon on the
right.
From the menu, select Edit Fields.
The Edit Field Parameters window modal appears.
Notice that the Base Column name cannot be edited, but you can change the Display Name of the column.
Change it from iso_cc
to ISO Country Code
.
Click Apply.
Under Dataset: World Life Expectancy, click Save.
As a result of this change, all new visuals created from this dataset use the new name automatically.
