Adapting the source data to the tLineChart schema

Procedure

  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.
  8. Click OK to save the mappings and close the Map Editor and propagate the output schemas to the output components.
