• a data file item or a query.
• a column of a Table control found in the current window or page.
  
• a List Box control found in the current window or page.
  
• a WLanguage array.
  
• data specified in the description window of the control or programmatically.
• a control of the current report (only for a report).

• Chart control in a window or page:
  The "CHART_MySalary" Chart control is used to view the evolution of a salary over the last four years in a Line chart.
  The "EDT_Salary1", "EDT_Salary2", "EDT_Salary3" and "EDT_Salary4" edit controls are used to type the salary for the corresponding year.
  In this example, write the following code in the "Initialization" event of the Chart control:
  
  // Add data into the chart
  grAddData(CHART_MySalary, 1, EDT_Salary1)
  grAddData(CHART_MySalary, 1, EDT_Salary2)
  grAddData(CHART_MySalary, 1, EDT_Salary3)
  grAddData(CHART_MySalary, 1, EDT_Salary4)
  
• Chart control in a state:
  The "RPT_MyReport" report prints the details (last name, first name, turnover) of the 10 best customers.
  The "CHART_MyChart" chart displays the turnover of each customer in a pie chart.
  In this example, write the following code in the "Before printing" event of the Body block:
  
  // Add data into the chart
  grAddData(CHART_MyChart, 1, MySource.Turnover)
  

Remarks

• If the fill mode is automatic, we advise you not to program the chart filling (with grAddData, grScatterAddDataXY, grStockAddData and grIncreaseData).
• The chart is automatically created by the window editor, page editor or report editor. There is no need to use grCreate to create it.
• The aspect of the chart and/or the display of text in the chart can be modified:
  • in the chart description ("Description" in the context menu of the control). For more details, see Chart control: Features in the editor.
  • via the functions for chart management.
