Example
// Add a data into the "CHART_MyChart" control.
// This data (whose value is 10) is added at the end of the first series.
grAddData(CHART_MyChart, 1, 10)
Syntax
grAddData(<Chart name> , <Series number> [, <Subscript>] , <Value>)
<Chart name>: Control name or character string (with quotes)
Name of chart to use. This name corresponds to:
  • the chart name defined by programming with grCreate. This name must be in quotation marks.
  • the name of Chart control (found in the window editor, page editor or report editor). This name must not be in quotation marks.
<Series number>: Integer
Number of the series into which a value will be added. If the specified series does not exist, the chart designer creates as many series as necessary in order to get a consistent matrix. All the created series are initialized to 0.
<Subscript>: Optional integer
Subscript of the data in the series into which a value must be added. If this parameter:
  • is not specified, the value is added at the end of the series.
  • is specified, the former value is replaced.
<Value>: Integer or real
Value to add.
Remarks

Adding data

  • The data added by grAddData will be taken into account during the next call to grDraw.
  • For a pie chart (grPie constant), only the data found in the first series is used. A Pie chart cannot be drawn if the data found in the first series is null.
  • For the "Stacked bar" charts, if the value of the first series is negative, the corresponding bar is oriented toward the bottom.

Adding data into the different types of charts
