The term array is used for a numerical data file.
ArtSGraph allows to load numerical data and to represent it graphically.
Data file must be a tab delimited text file having arbitrary number of columns. However, ArtSGraph will use only 2 columns – one for abscissas and one for ordinates.
In the simplest case a file has 2 numbers per line (for abscissa and ordinate), each represents a single point. Total number of lines in the file should not exceed 1000.
Alternatively, you can load array in auto-abscises mode. In this mode ArtSGraph uses only one column (for ordinates) and automatically constructs abscissas by given first-point value and even step.
The simplest way to prepare a tab-delimited file is to use MS Excel, fill a sheet with desirable data and to save it as type Text(tab delimited) (*.txt).
