Adapting the source data to the tBarChart schema

  1. Double-click the tMap to open the
    Map Editor.

    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.
  2. Use the Schema editor to add three
    columns to each output table: series (string),
    category (string), and value
    (integer).
  3. 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.
  4. Drop the City column of the input table onto the
    category column of each output table.
  5. Drop the Population column of the input table onto
    the value column of the Population
    table.
  6. Drop the Area column of the input table onto the
    value column of the Area
    table.
  7. Drop the Density column of the input table onto the
    value column of the Density
    table.
