Adapting the source data to the tLineChart 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
    TV_A, TV_B, and TV_C on the
    output panel.
  2. Use the Schema editor to add three
    columns to each output table: series (string),
    x (integer), and y
    (integer).
  3. In the relevant Expression field of the
    output tables, enter the text to be presented in the legend area of the line
    chart, TV A, TV B, and TV C
    respectively in this example.
  4. Drop the Week column of the input table onto the
    x column of each output table.
  5. Drop the Mins_TVA column of the input table onto the
    y column of the TV_A table.
  6. Drop the Mins_TVB column of the input table onto the
    y column of the TV_B table.
  7. Drop the Mins_TVC column of the input table onto the
    y column of the TV_C table.
