### Import curves from a file

The PlotCurveFile node allows you to initialize curves by reading data in a given file.

The format of the file is :
# CurveName1 CurveName2....CurveNameN
x1_AllCurves y1_Curve1 y1_Curve2....y1_CurveN
x2_AllCurves y2_Curve1 y2_Curve2....y2_CurveN
. .
xn_AllCurves yn_Curve1 yn_Curve2....yn_CurveN
This is an example of a file :
# VelocityX VelocityY
0 1.75 2.5
20 5.12 1.2
25 1.52 2.2

Note that the first is optional and all curves have the same X-axis values.
