grScatterAddDataXY (Function) In french: grNuageAjouteDonnéeXY Adds a data into a "Scatter" chart. Reminder: By default, a chart contains no data.
// Adds a data into the "Scatter" chart named "MyChart".
// This value (10, 20) is added at the end of the first series.
grScatterAddDataXY("MyChart", 1, 10, 20)
// Adds a data into the CHART_MyChart control ("Scatter" chart).
// This value (20, 10) is added at the end of the first series.
grScatterAddDataXY(CHART_MyChart, 1, 20, 10)
Syntax
grScatterAddDataXY(<Chart name> , <Series number> [, <Index>] , <X value> , <Y value>)
<Chart name>: Control name or character string Name of the chart to be used. This name corresponds to:- the chart name defined through programming with grCreate.
- the name of the Chart control in the window, page or report editor.
<Series number>: Integer Number of the series in which a point must be initialized. 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. <Index>: Optional integer Index of the data to initialize in the series. If this parameter is not specified, the value is added at the end of the series. <X value>: Real Horizontal coordinate (X-coordinate) of the point to add. <Y value>: Real Vertical coordinate (Y-coordinate) of the point to add. Remarks Adding data into a Scatter chart The data defined by grScatterAddDataXY will be taken into account during the next call to grDraw. Adding data into a chart grAddData is used to add data into a chart (pie, column, ...) Depending on the type of chart, specific functions can also be used to add data: Reminder: To add a value to the data in a chart, use grIncreaseData. Equivalence We recommend that you use grScatterAddDataXY to add data into the "Scatter" charts. However, you can also use grAddData. The following syntax:
grScatterAddDataXY(CHART_MyChart, i, 1, 10, 20)
est is equivalent to the syntax:
grAddData(CHART_MyChart, i*2-1, 1, 10)
grAddData(CHART_MyChart, i*2, 1, 20)
