Detailed Description

An annotated NSData type.

CPTNumericData combines a data buffer with information about the data (shape, data type, size, etc.). The data is assumed to be an array of one or more dimensions of a single type of numeric data. Each numeric value in the array, which can be more than one byte in size, is referred to as a “sample”. The structure of this object is similar to the NumPy ndarray object.

The supported data types are:

1, 2, 4, and 8-byte signed integers
1, 2, 4, and 8-byte unsigned integers
float and double floating point numbers
float complex and double complex floating point complex numbers
NSDecimal base-10 numbers

All integer and floating point types can be represented using big endian or little endian byte order. Complex and decimal types support only the the host system’s native byte order.
