Data Format:

RtPlot expects the data in the file to be ordered in one or more columns. The columns may be delimited either by whitespaces or a comma (CSV). A column which is not being displayed may contain non numeric data as well. Lines starting with # are considered as comments. If "NaN" or "nan" are the first 3 characters of a line, the points preceding and following that line are not connected. The following examples are valid for display in RtPlot:

#Columns separated by spaces
0.0 1.0
1.0 2.0
2.0 3.0


#Columns separated by comma 
0.0,1.0,2.0
1.0,2.0,3.0
2.0,3.0,4.0


#Columns separated by comma with missing data 
0.0,1.0,,3.0
1.0,,3.0,4.0
2.0,3.0,,5.0


#Some columns containing non-numeric data 
0.0,HELLO,,3.0
1.0,,WORLD,4.0
2.0,3.0,,5.0


#Second and third data points are not connected
0.0 0.0
1.0 1.0
NaN
0.0 1.0
1.0 0.0

Numeric data can be represented as integers and fixed or floating point numbers.
