// 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)
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.
Only the interactive Chart controls are available.
<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.
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
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
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)
