Creates a specific type of chart.
Remarks:
  • It is recommended to create a Chart control directly rather than using grCreate. Indeed, the Chart control offers many more features.
  • This function can only be used to create a chart through programming. This function cannot be used in the window editor, page editor or report editor.
Example
// Create a column chart
// (and save the parameters modified by the user)
grCreate("MyChart", grColumn)

Remarks

Creating and drawing a chart through programming

To create and draw a chart:

Drawing several charts at the same time

Several charts with the same name cannot exist at the same time.
To draw several charts at the same time (in one or more windows for example), different chart names must be specified.

Charts and threads

A single chart can be handled in a thread.
Consequences:
  • Two threads cannot handle the same chart.
  • A chart created in a thread is automatically destroyed at the end of this thread. The chart exists in the thread that contains the call to grCreate.

Default values of a chart created through programming

The default values of a chart are as follows:
