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.
For example, if the Chart control displays 2 lines, this is used to identify the line for which the data must be added. If the specified number does not exist, the series between the last existing series and the specified number are automatically created and initialized to 0. <Subscript>: Optional integer Subscript of the data in the series into which a value must be added.
For example, for a Line chart, this parameter corresponds to the X-axis of the value to add. 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. For example, for a Line chart, this parameter corresponds to the Y-axis of the 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 - For the Scatter charts, we recommend that you use grScatterAddDataXY.
- For the stock charts, we recommend that you use grStockAddData.
