You can see an input table on the input panel, row1 in this example, and three empty output tables, named
Population, Area, and Density on the
output panel.
Use the Schema editor to add three
columns to each output table: series (string),
category (string), and value
(integer).
In the relevant Expression field of the
output tables, enter the text to be presented in the legend area of the bar
chart, "Population (x1000 people)", "Land area
(km2)", and "Population density (people/km2)"
respectively in this example.
Drop the City column of the input table onto the
category column of each output table.
Drop the Population column of the input table onto
the value column of the Population
table.
Drop the Area column of the input table onto the
value column of the Area
table.
Drop the Density column of the input table onto the
value column of the Density
table.
Click OK to save the mappings and close
the Map Editor and propagate the output
schemas to the output components.
