DXImportNetCDF

Function

Imports data from a netCDF file.

Syntax

#include <dx/dx.h>

Object DXImportNetCDF(char *filename, char **variable, int *start,
int *end, int *delta)

Functional Details

The routine creates a new Field or Group Object to hold the data that are to be imported. The filename parameter is the name of a data file in netCDF format. The variable parameter specifies a NULL-terminated list of strings that identify the variables to be imported. If more than one is specified, the Objects are collected together and a Group is returned.

For Series data, *start, *end, and *delta are used to control which indexed Series members are read in. If start is NULL, it defaults to the beginning of the series; if end is NULL, it defaults to the end of the series; if delta is NULL, it defaults to 1 (one).

For additional information on the Data Explorer requirements and conventions for the netCDF file, see Appendix B. "Importing Data: File Formats" in IBM Visualization Data Explorer User's Guide.

Return Value

Returns a pointer to the Object or returns NULL and sets an error code.
