This page contains a glossary of terms used in Open Curves.

Term	Meaning
curve	A plottable data series object. Also referred to as a 'plot'.
column	Consecutive curves from a single source may be referred to as columns. This is derived from the way a text file source can be considered as a table, with each line a new row and each row containing multiple columns of data.
expression	A set of operations used to generate new data from existing data.
generator	An object which creates curves. Also 'loader'.
plot	An alias for 'curve'.
loader	An alias for 'generator'.
source	Identifies where a set of curves came from; e.g., file, serial connection, expressions. A single source will normally generate multiple curves.
time column	The column in a data source which is used to derive a time value for other curves from the same source. Uses one-based indexing, allowing a zero value to indicate a lack of a time column.
