Curves are read from an ASCII file with the Read Curves panel. The format of the input file is assumed is as follows:  

 

XYDATA,TITLE

X1, Y1

X2, Y2

.

.

.

ENDDATA

XYDATA,TITLE

X1, Y1

X2, Y2

.

.

.

ENDDATA

 

Each curve in the file is defined in a block format. The block begins with the statement, XYDATA.  After XYDATA, the title assigned to the curve, which is displayed in the legend, follows on the same line.  Point data follows with a set of (x, y) data pairs on each line.  The block ends with an ENDDATA statement. In the above example, there are two blocks of data, which define two curves.
