Detailed Description

A namespace to set the standard for indexing into 2 dimension data point tuple.

This namespace sets the standard to indexing into columns of an DataSource representing 2 dimensional data points. Each row of the DataSource is data point with it attribute represented in columns. The enumeration specified in the namespace gives the column indices.

Note:

In the case that the tuple is being filled from the contents of a histogram, the Y coordinate should be the contents of the bin divided by the bin width and the YERR should be half the bin width.
