I would like to make a plot of several data sets that are stored in a text file (tab-separated). Is there a way of defining the x-range for which some (not all) of the data sets should be plotted? I want some data sets to plot fully, and others only in specified ranges.
Consider the following example:
x B C D
1 3 4 5
2 4 6 3
3 4 7 4
4 5 7 2
should be plotted so that all four values of columns B and C are plotted against the x values, but only the values for which x is in the range [2,3] should be plotted for column D.
In other words, I want to use \addplot three times in the same axis environment, and define the x-range separately for each data set.
The condition cannot be the index. I need to use this for large data files, for which I do not know the indices of the data points I need. Hence, the input to define the points to plot must be an x interval.
