Example
// 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> [, <Subscript>] , <X value> , <Y value>)
<Chart name>: Character string (with or without quotes)
Name of chart to use. This name corresponds to:
  • the chart name defined by programming with grCreate.
  • the name of Chart control found in the window editor, page editor 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.
<Subscript>: Optional integer
Subscript 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:
  • For the stock charts, we recommend that you use grStockAddData.
  • Versions 21 and later
    For the Heatmap charts, we recommend that you use grHMAddData.
    New in version 21
    For the Heatmap charts, we recommend that you use grHMAddData.
    For the Heatmap charts, we recommend that you use grHMAddData.
  • Versions 20 and later
    For the Sunburst charts, we recommend that you use grSunburstAddData.
    New in version 20
    For the Sunburst charts, we recommend that you use grSunburstAddData.
    For the Sunburst charts, we recommend that you use grSunburstAddData.
  • Versions 18 and later
    For the Surface charts, we recommend that you use grSurfaceAddData.
    New in version 18
    For the Surface charts, we recommend that you use grSurfaceAddData.
    For the Surface charts, we recommend that you use grSurfaceAddData.
Reminder: To add a value to a chart data, use grIncreaseData.

Equivalence

We recommend that you use grScatterAddDataXY to add data into the "Scatter" charts. However, you also have the ability to 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)
