Stored procedures
Adds a data into a chart.
Caution: A specific WLanguage function must be used for the "advanced" charts (see "Notes").
// Add a data into the "CHART_MyChart" control.
// This data (whose value is 10) is added at the end of the first series.
CHART_MyChart.AddData(1, 10)
<Chart control>.AddData(<Series number> [, <Subscript>] , <Value>)
<Chart control>: Control name
Name of the Chart control to use (found in the window editor, page editor or report editor).
<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.

Adding data

  • The data added by <Chart>.AddData will be taken into account during the next call to <Chart>.Draw.
  • 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.
